1
00:00:00.000 --> 00:00:00.450
i'm.

2
00:00:02.879 --> 00:00:04.170
Albert De Roeck: holding office great.

3
00:00:05.279 --> 00:00:15.570
Albert De Roeck: So this is a special session, where we are going to look at what happens may still happen in the snow mask process.

4
00:00:16.710 --> 00:00:23.460
Albert De Roeck: driven process for the future in the next few years of the energy physics program over there.

5
00:00:24.300 --> 00:00:26.850
Albert De Roeck: And there were several groups.

6
00:00:27.150 --> 00:00:27.540
Albert De Roeck: We have.

7
00:00:27.570 --> 00:00:40.650
Albert De Roeck: The high energy frontier the process from tf between the frontier and even more, but we have like three excellent speakers today we're going to tell us what.

8
00:00:41.940 --> 00:00:57.810
Albert De Roeck: First need throw me off to these groups, what the news is on there for bsm is like central take it for the long list articles, so that everybody before and we started with Simon and we will talk about the energy from here for.

9
00:00:59.760 --> 00:01:00.120
Albert De Roeck: All y'all.

10
00:01:02.460 --> 00:01:06.720
Simon Knapen: Thank you good afternoon everyone Good morning, whatever it tends to be in.

11
00:01:07.770 --> 00:01:09.930
Simon Knapen: See so i'm going to tell you a little bit about.

12
00:01:11.040 --> 00:01:19.470
Simon Knapen: what's, what does the snow must LP section is going to look like for energy report, at least for now.

13
00:01:20.160 --> 00:01:25.920
Simon Knapen: So the convenience for this falls under what's called the four nine so that's energy frontier working with nine.

14
00:01:26.580 --> 00:01:41.010
Simon Knapen: Which is general exploration sort of it's like a grab bag for anything that's not dark matter or susie effectively, and so the convenience of this working group are two likud's and simoni, and so they subcontract that.

15
00:01:42.720 --> 00:01:45.750
Simon Knapen: Julian myself to to help a little bit with writing.

16
00:01:46.830 --> 00:01:52.620
Simon Knapen: The LP section particular which what is what i'll focus on here, so the objective.

17
00:01:53.730 --> 00:02:02.880
Simon Knapen: Of this thing is not to be an exhaustive summary of of the progress and lps for the benefit of the llp community we just don't have the space for that.

18
00:02:03.660 --> 00:02:14.100
Simon Knapen: But it's meant it's aimed at the sort of broader energy frontier community and emphasizing that lps or orange and so they're very motivated and places to look for new physics.

19
00:02:14.970 --> 00:02:23.400
Simon Knapen: which you know, one of the things we're using is of course usual the usual plot by by Brian to illustrate that this is a generic thing that you can expect.

20
00:02:24.930 --> 00:02:32.700
Simon Knapen: As well as that they cannot be taken for granted, so, in the sense that we need to highlight the upgrades to the storm physics case for someone's ability detectors.

21
00:02:33.090 --> 00:02:43.170
Simon Knapen: And when you're building or considering a future accelerator detector facility, you have to think in advance about the needs of lps and particular tracker construction triggering and so forth.

22
00:02:44.220 --> 00:02:49.470
Simon Knapen: So will also provide a few very limited set of benchmarks, or we can compare.

23
00:02:50.760 --> 00:03:08.160
Simon Knapen: Different different facilities and experiments with each other, based on what was submitted and finally we summarize the LP related contributions snowmass, and so this will all be input to the big energy frontier summary report that will come out later.

24
00:03:09.750 --> 00:03:21.030
Simon Knapen: So specifically energy from tier nine is called more general exploration so lps is one part of it as two other major sub sections one is.

25
00:03:21.570 --> 00:03:30.960
Simon Knapen: Just new new bows and some heavy residences So these are your as the PRIMES and whatnot and then heavy firmly on So these are vector like for me on 72 leptons and so forth.

26
00:03:31.740 --> 00:03:40.530
Simon Knapen: fall and the new firmly on the category, and then we have one with particles which have some overlap, of course, we didn't have it, too, and so this report was.

27
00:03:41.580 --> 00:03:57.510
Simon Knapen: Something along with particles are also in year 4248 and here for 10 years or two is exotic exotic case eight is model specific searches will be on a certain model physics are mostly supersymmetry composite eggs and equals 10 is a dark matter.

28
00:03:59.070 --> 00:04:10.380
Simon Knapen: And so, this report is being merged, it should be almost complete now with that you have or eight and nine into one large summary report for bsm at.

29
00:04:11.610 --> 00:04:21.360
Simon Knapen: The energy frontier and so section nine is at least what is now section nine is as long as particles in here see an outline of this section so.

30
00:04:21.990 --> 00:04:28.020
Simon Knapen: looking a little bit more closely, we have three sub sections one is about strategies and detectors.

31
00:04:28.980 --> 00:04:38.460
Simon Knapen: As far as the main detectors go, and so this is necessarily focused on high Leumi upgrades as well as some general considerations of what you would need.

32
00:04:38.910 --> 00:04:56.490
Simon Knapen: At a future collider whether it's the left on our hadron collider necessarily a little bit more vague than the things that we already know, for the elite see there's a short subsection outline what are the various dedicated detectors for lps and why we think that they are.

33
00:04:58.320 --> 00:05:09.630
Simon Knapen: and very important compliment to the main detectors of the elysee and what the various reaches are and so forth, and then a few handful of benchmarks to wrap up.

34
00:05:10.740 --> 00:05:17.430
Simon Knapen: At the end, so the whole thing is about 11 pages right now and it shouldn't grow much beyond that anymore.

35
00:05:19.500 --> 00:05:27.960
Simon Knapen: So, as far as strategy and detector R amp D is concerned, I think the vast majority of what's in here is not going to be new to the LGBT community it's relatively.

36
00:05:28.500 --> 00:05:33.990
Simon Knapen: Obvious stuff but it's stuff that needs to be emphasized, and think to to the rest of the Community, in the sense that.

37
00:05:34.710 --> 00:05:39.060
Simon Knapen: They might not necessarily think about that, when they're not working them know a little piece.

38
00:05:39.840 --> 00:05:45.540
Simon Knapen: Frequently so so, for example, particle identification is extremely valuable for us like things like the dx time of flight, etc.

39
00:05:46.110 --> 00:05:55.110
Simon Knapen: which we have the lsc, but we should not take for granted that these capabilities will will be maintained at the future facility and it's important to emphasize that.

40
00:05:55.710 --> 00:06:05.820
Simon Knapen: Vertical solution for example of yellow is a fantastic LP detector and support is also going to be important, and there are things like triggers and so forth.

41
00:06:07.170 --> 00:06:18.240
Simon Knapen: As far as strong versus aside from strong versus electric production, we also mentioned that not all colliders are born equal when it comes to to LP LP because.

42
00:06:18.630 --> 00:06:35.100
Simon Knapen: it's quality will be harder to look at long of protocols at the hadron or your machine and so, if one such machines are being considered and challenges are background challenges are more severe and we need to make sure that they get mitigated in the detective design.

43
00:06:36.420 --> 00:06:43.980
Simon Knapen: But hopefully most of the things that are in this section are going to be fairly well known to to the people that are dialed into this talk over here.

44
00:06:45.330 --> 00:06:50.580
Simon Knapen: For the dedicated detectors so we emphasize why.

45
00:06:51.750 --> 00:07:08.910
Simon Knapen: They are complementing the reach of auto cms in La CB and what the differences between having central and forward detectors in terms of the Center of mass at which the M and N, which to llp is being produced and they emphasize is that.

46
00:07:10.080 --> 00:07:21.030
Simon Knapen: These external external factors are more aimed at in most cases, more aimed at somewhat later lps as compared to what doesn't seem so doing, with the exception of materials line some.

47
00:07:21.840 --> 00:07:31.350
Simon Knapen: scenarios and then we also include we include these two this is this plot that we include to illustrate that point and here is the plot of I think made by Matthew at some point.

48
00:07:32.610 --> 00:07:37.110
Simon Knapen: Just over outlying that the whole spectrum of proposals in a month.

49
00:07:38.670 --> 00:07:45.240
Simon Knapen: So we group these things as follows, for forward central charged and future colliders, and so this is the every.

50
00:07:46.230 --> 00:07:55.080
Simon Knapen: detector here is getting roughly a paragraph we don't have a lot of space for plots and things like that so apologies for that space is very limited.

51
00:07:55.950 --> 00:08:09.480
Simon Knapen: I put out reacts in brackets we just it just mentioned, but it's not really discussed in the sense that the moment it doesn't look like there's a strong path forward for this experiment, given the upgrade plans of the ELISE experiment.

52
00:08:11.220 --> 00:08:28.320
Simon Knapen: But so that's sort of what this section looks like so of course the sensitivity, plus of all of these things are very important and, to a large extent they're included in either in the next section or in the in the article six report that that defined, you will talk about in a bit.

53
00:08:29.640 --> 00:08:40.140
Simon Knapen: So for signatures yeah we had to be very selective again we only have room for handful plots and so specifically that means up for lifelong with particles features a lot of stuff.

54
00:08:40.740 --> 00:08:47.340
Simon Knapen: We restrict ourselves to things that are made an exotic kings the case, and so we were talking mostly that the support is mostly for granted that the energy frontier.

55
00:08:47.940 --> 00:08:51.720
Simon Knapen: And so, that means that things like dark photons and having nickel atoms and so forth.

56
00:08:52.290 --> 00:09:05.340
Simon Knapen: They are mentioned are being discussed, but the actual sensitivity plots I believe are featured in order for six months to find you might tell us a little bit more about this later, and of course we will cross reference to make sure that people can easily find.

57
00:09:06.510 --> 00:09:08.130
Simon Knapen: deals the sensitivity curves.

58
00:09:09.960 --> 00:09:19.860
Simon Knapen: For charged a little piece, we felt that the disappearing track searches a very generic and very tragically motivated search and so we included that, so this is a summary plot.

59
00:09:20.520 --> 00:09:29.220
Simon Knapen: That we compiled as a function of the lifetime of the Church, you know versus the muscle church universes The lifetime specifically picking a he's you know here.

60
00:09:31.500 --> 00:09:37.230
Simon Knapen: For these various collider options that were submitted into dashed line here is the.

61
00:09:39.480 --> 00:09:43.380
Simon Knapen: Is the purity xena lifetime, so if you just have a natural splitting of the you know.

62
00:09:45.360 --> 00:10:01.860
Simon Knapen: Putting this together, this was put together assuming assuming that you live on this this dashed line over here, this was put together for all these collider options by policy and company in this paper, and so this plot is also produced here.

63
00:10:03.180 --> 00:10:08.490
Simon Knapen: Where you see that dashed line is sort of the dark matter, but the preferred document of benchmark.

64
00:10:09.300 --> 00:10:16.770
Simon Knapen: The indirect detection line over here look they scary and that's just because this is not a very natural way of plotting.

65
00:10:17.310 --> 00:10:32.160
Simon Knapen: The indirect detection limits, because they come in from a different angle, in some way so there's lots of caveats corresponding to these green bar and those caveats that being explained in the text, but we felt that be be good to include them anyways just for completeness sake.

66
00:10:33.180 --> 00:10:37.500
Simon Knapen: But the fact that is green bars here doesn't mean that the rest of these things are useless.

67
00:10:38.640 --> 00:10:40.290
Simon Knapen: And we try to explain that carefully.

68
00:10:42.180 --> 00:10:55.050
Simon Knapen: For like lps we have one benchmark of expert they came to to skip to like scale or as light particles s one where we set the branch, and we should do murals to be 100%.

69
00:10:56.160 --> 00:11:04.350
Simon Knapen: With a half a gv mouse, and the other one where we became mostly to how to answer these are sort of to quote unquote more extreme cases in some sense.

70
00:11:04.860 --> 00:11:13.380
Simon Knapen: In terms of what the branch ratios can be, and so in blue you see the existing searches and then the the other colors are.

71
00:11:14.280 --> 00:11:29.970
Simon Knapen: Various proposal, so, in some cases, we only had to lifetime point so that's what you see here, for instance, for the cms counting analysis on the left, and so you that doesn't mean that there's no sensitivity in between you sort of have to mentally interpolate and play the lines over here.

72
00:11:32.160 --> 00:11:39.750
Simon Knapen: so few comments here, so we included this so not all such as were like at a specific are the same mass point, so we have to do some.

73
00:11:40.680 --> 00:11:47.580
Simon Knapen: sort of you know, sensible extrapolations in some points will be included all those such as though we were comfortable extrapolating.

74
00:11:47.940 --> 00:11:58.620
Simon Knapen: and have those weekly most of the strongest ones, specifically for how long this there's a few more but they either at much higher mosses already isn't to be weakened and the two that we show over again.

75
00:12:00.660 --> 00:12:09.450
Simon Knapen: There are studies on their way, in particular for Methuselah also for this left hand panel which is not yet completed, but if that gets completed will add that as well.

76
00:12:11.280 --> 00:12:25.860
Simon Knapen: They should here is because it's a relatively light particle the opening angles, can be small and it's not obvious how that can be reconstructed, given the tracking resolution of various detector so that's why it's a bit more challenging than the lower right hand side.

77
00:12:27.030 --> 00:12:31.440
Simon Knapen: The word high Leumi results in particular for this one over here.

78
00:12:32.820 --> 00:12:41.850
Simon Knapen: protections router However, the actual analysis was before was made after the projections, and it has already outperformed the projection so the projection is unfortunately not included.

79
00:12:42.390 --> 00:12:49.740
Simon Knapen: Because it would be weaker than the current limit at the moment, and so we don't have high Leumi extrapolations for these various.

80
00:12:51.660 --> 00:12:54.630
Simon Knapen: searches at the moment, which is a bit unfortunate, but it is what it is.

81
00:12:56.040 --> 00:12:56.820
Simon Knapen: yeah.

82
00:12:58.140 --> 00:12:59.760
Simon Knapen: And then, finally, we have some.

83
00:13:01.020 --> 00:13:04.620
Simon Knapen: plots about having a heavy along with protocol so for a color.

84
00:13:06.270 --> 00:13:20.940
Simon Knapen: We chose we susie is here a pretty pretty good benchmark in general, so we looked like look to get Guido here, so you can have in mind splits was the scenario where have a goal, you know the King displaced two jet's angeleno, and so this is the.

85
00:13:22.380 --> 00:13:27.960
Simon Knapen: projection that we got from one of the office White Papers, unfortunately, there is no we didn't find any.

86
00:13:28.650 --> 00:13:37.560
Simon Knapen: convert corresponding result for future, how do I machine, so if we have missed something, and you know about something, please let us know and then we'll add that and make a summary plot.

87
00:13:38.070 --> 00:13:58.020
Simon Knapen: Including as well, and for that, for example, along with xena which could be either a gauge mediation or an rp scenario, this is the summary, so we have like a click the currency in my search for displaced jet displays for tourism in a tracker as well as some protection.

88
00:13:59.670 --> 00:14:11.820
Simon Knapen: And then finally for Doc showers there's a long White Paper exhaustively being compiled and so we just very briefly explain what the showers are why they're important to look for.

89
00:14:12.300 --> 00:14:24.450
Simon Knapen: And of course reference, the White Paper and then other roles and preferences there but it's all very condensed so that's essentially it.

90
00:14:24.990 --> 00:14:32.970
Simon Knapen: You will find, hopefully, either in the next few days, it might be already there on this link, you will find the phobia some reports so you want to look for Section nine.

91
00:14:33.810 --> 00:14:40.260
Simon Knapen: For the little piece section, and so the idea is that people can provide comments and feedback and support.

92
00:14:40.770 --> 00:14:57.360
Simon Knapen: And you can submit that there will be like a Google form or a Google Doc link to this page where you can leave your comments would be great if you can let us know who you are so that, if we have you know when you make a comment, so that if we.

93
00:14:58.530 --> 00:15:02.970
Simon Knapen: have difficulty interpreting what you're saying that we can always get in touch and ask for clarification.

94
00:15:04.020 --> 00:15:09.570
Simon Knapen: Feedback would be appreciated me sooner is always better but ideally before to Seattle meeting, which will be meant to live.

95
00:15:11.310 --> 00:15:13.170
Simon Knapen: yeah anyway so that's all I have.

96
00:15:18.180 --> 00:15:19.560
Albert De Roeck: summarizing this nicely.

97
00:15:21.540 --> 00:15:21.750
Albert De Roeck: we're.

98
00:15:21.930 --> 00:15:23.820
Albert De Roeck: gonna have some questions on this.

99
00:15:25.920 --> 00:15:37.500
Albert De Roeck: First, one in this effort, I mean I you know there were so many things to follow his mouth as possible basically all everything and then the.

100
00:15:39.210 --> 00:15:47.310
Albert De Roeck: Memories that, in your view, was there anything during this yesterday is basically done.

101
00:15:47.880 --> 00:15:49.020
Simon Knapen: For snow must be for.

102
00:15:49.020 --> 00:15:53.280
Albert De Roeck: Something new, I know, for example, the SPS and.

103
00:15:53.610 --> 00:15:54.150
Albert De Roeck: Say save.

104
00:15:55.170 --> 00:15:59.580
Albert De Roeck: US detectors in the context of snow mouth, because that was the right.

105
00:15:59.610 --> 00:16:00.660
Albert De Roeck: moments before with these.

106
00:16:00.900 --> 00:16:03.960
Albert De Roeck: Are there other things, maybe smaller than your special.

107
00:16:05.280 --> 00:16:08.610
Albert De Roeck: Sector techniques or something along with articles that.

108
00:16:09.690 --> 00:16:14.310
Albert De Roeck: were discussed for helping and making the program leaders role.

109
00:16:16.140 --> 00:16:24.930
Simon Knapen: yeah so I should have made a backup slide about that probably I there were a few White Papers specifically about tracking especially track the track triggers.

110
00:16:26.520 --> 00:16:27.060
Simon Knapen: Using.

111
00:16:28.230 --> 00:16:30.540
Simon Knapen: It came as well, especially the cms.

112
00:16:31.770 --> 00:16:32.790
Simon Knapen: double layer scheme.

113
00:16:34.980 --> 00:16:35.970
Albert De Roeck: word is meeting.

114
00:16:38.400 --> 00:16:48.900
Albert De Roeck: Something obscure so that did not get so much attention on the local local, but the multimedia again.

115
00:16:57.840 --> 00:17:01.740
José Zurita: Yes, so I wanted to quickly as Simon about this 20.

116
00:17:01.770 --> 00:17:06.630
José Zurita: pages because probably you said, there are many copy it's really just the caveats.

117
00:17:07.290 --> 00:17:19.560
José Zurita: require more than two pages that if someone wants to give you feedback do these 12 pages include references because normally the points that we want my try to make will include like pointed out to a paper or some publication or or document.

118
00:17:19.590 --> 00:17:24.270
Simon Knapen: No, no, the 12 pages don't include references and to the best of my knowledge.

119
00:17:25.530 --> 00:17:32.910
Simon Knapen: There is no upper bound on references now you know I, you should all feel free to let us know.

120
00:17:32.910 --> 00:17:35.370
Simon Knapen: If you feel that you should be cited, however.

121
00:17:36.570 --> 00:17:38.910
Simon Knapen: You know, we have the thing remains readable as.

122
00:17:38.910 --> 00:17:49.020
José Zurita: Well, right and I get your point, but you know, sometimes it's much easier than coming out in a paragraph to work basis it distorts everything, but just a little bit was discussing the affection.

123
00:17:49.050 --> 00:17:52.560
Simon Knapen: love the salad paper, yes, yes, yes, exactly yeah so the ideas.

124
00:17:54.480 --> 00:17:57.600
Simon Knapen: Right now, so again like we're looking at.

125
00:17:58.920 --> 00:18:01.920
Simon Knapen: The hope is that it's somewhat for looking text right.

126
00:18:03.600 --> 00:18:07.380
Simon Knapen: And maybe maybe we're due for another review of of.

127
00:18:07.680 --> 00:18:11.760
Simon Knapen: What the state of the art is and lps in our field but that's not what this is going to be.

128
00:18:13.140 --> 00:18:17.790
Simon Knapen: But yeah so of course if there are things that are important going for for the future of the Program.

129
00:18:19.020 --> 00:18:29.760
Simon Knapen: That were missed, I mean that's the that's why the report is made public before it's it's made final so that we can, and especially if you know some of the things that are.

130
00:18:29.760 --> 00:18:44.100
Simon Knapen: included they're not represented properly we'd like to know, and because this was put together as you, as you know, in a relatively short amount of time, so it's very plausible that things were missed or not represented in the most optimal optimal fashion.

131
00:18:45.300 --> 00:18:45.810
Simon Knapen: Thank you.

132
00:18:47.100 --> 00:19:00.720
Juliette Alimena: Just to maybe quickly add i'm Simon and I really tried to do at least site everything that would be Bella mean that is relevant and if we miss something we really want to include it, so please let us know as sunset.

133
00:19:05.550 --> 00:19:07.860
Albert De Roeck: So, as we were talking earlier.

134
00:19:09.930 --> 00:19:13.260
Albert De Roeck: On the life, for example, like this that's not yet.

135
00:19:15.840 --> 00:19:16.110
Albert De Roeck: My.

136
00:19:18.480 --> 00:19:19.530
Albert De Roeck: question to both of you.

137
00:19:24.750 --> 00:19:26.670
Simon Knapen: have a hard time hearing you can you.

138
00:19:29.520 --> 00:19:31.470
Albert De Roeck: I don't know, maybe specify.

139
00:19:34.500 --> 00:19:36.000
Albert De Roeck: We heard before so.

140
00:19:37.470 --> 00:19:41.910
Albert De Roeck: You better idea for for for a big factor.

141
00:19:50.070 --> 00:19:55.140
Simon Knapen: you're asking something about a new sector ideas as well and i'm not sure that I got the good Albert.

142
00:19:55.200 --> 00:19:57.900
James Beacham (he/him): or the other you're very you're very far from Michael can.

143
00:20:01.170 --> 00:20:02.100
Albert De Roeck: you hear me now or.

144
00:20:02.400 --> 00:20:04.080
Simon Knapen: lots of good yeah yeah.

145
00:20:04.260 --> 00:20:06.810
Albert De Roeck: Okay, I put the way that that's.

146
00:20:08.400 --> 00:20:12.690
Albert De Roeck: The question was on the Juliet you, you are also there before them the delights.

147
00:20:13.710 --> 00:20:21.060
Albert De Roeck: detectors that already something that that manages to get sentence in there, or have not yet is it.

148
00:20:22.590 --> 00:20:32.580
Albert De Roeck: across that that's a concept of having like in my Tuzla close by central detector but you need an extended whole for that forces things.

149
00:20:33.600 --> 00:20:35.550
Albert De Roeck: For the FCC ah ah.

150
00:20:35.640 --> 00:20:36.240
Albert De Roeck: So that's.

151
00:20:36.510 --> 00:20:40.950
Simon Knapen: way down, yes, yes yeah that's right, so there is a seaman managed to.

152
00:20:42.660 --> 00:20:43.500
Simon Knapen: manage to go back.

153
00:20:46.740 --> 00:20:54.390
Simon Knapen: yeah so there's a sub section here about future colliders which there is a number of papers that were written about this last year and a half.

154
00:20:55.680 --> 00:20:58.770
Simon Knapen: Vote for SEC E and F G H h.

155
00:21:00.060 --> 00:21:04.680
Simon Knapen: Which discuss these, and so they were not in the context of snowmass but are included anyways.

156
00:21:06.720 --> 00:21:17.130
Simon Knapen: And we have some general consideration of things you might want to think about, especially at, for instance, the hadron machine and it's quite you know it's probably very well motivated to do this.

157
00:21:17.550 --> 00:21:25.680
Simon Knapen: Given that at the moment we don't know if we can, to the best of my knowledge, we don't know if we can look for longer particles at 100 TV Hello machine right it's not you know.

158
00:21:25.800 --> 00:21:31.260
Simon Knapen: it's not knowing that you can do that with a simple detectors at the moment, given possible backgrounds well for our left on machine.

159
00:21:32.700 --> 00:21:40.560
Simon Knapen: I think the case probably requires a little bit more study in the sense that the triggers will it will be essentially what i'm being told the trigger let's read out.

160
00:21:41.010 --> 00:21:44.940
Simon Knapen: And you'd have very good reconstruction probably very low backgrounds.

161
00:21:45.810 --> 00:21:59.220
Simon Knapen: So, for your external detector to beat your main detector it might have to be very large like or innovative for regime like a central detector in particular might not be as useful and left on machine have done it would be machine.

162
00:22:00.480 --> 00:22:02.340
Simon Knapen: So those are some general thoughts that are included.

163
00:22:02.790 --> 00:22:03.780
Albert De Roeck: Okay, but.

164
00:22:03.960 --> 00:22:05.430
Albert De Roeck: yeah any final.

165
00:22:06.300 --> 00:22:17.130
Juliette Alimena: yeah Oh, I was just going to add that the talk and the the paper that you're talking about that includes the delight detector proposal, it is included in our summary I.

166
00:22:17.130 --> 00:22:17.730
Albert De Roeck: Just checked.

167
00:22:20.160 --> 00:22:23.220
Simon Knapen: Okay sorry that the light okay I didn't I didn't put that I didn't.

168
00:22:24.630 --> 00:22:27.600
Simon Knapen: Catch that you were talking about the name of that detector rather than just like.

169
00:22:27.990 --> 00:22:28.770
Light particles.

170
00:22:31.260 --> 00:22:31.770
Simon Knapen: yeah.

171
00:22:31.950 --> 00:22:36.360
Albert De Roeck: Any any final question for this contribution.

172
00:22:40.260 --> 00:22:42.690
Albert De Roeck: I see none so thanks Simon and.

173
00:22:43.230 --> 00:22:44.010
Albert De Roeck: We go to.

174
00:22:44.250 --> 00:22:51.660
Albert De Roeck: Define your on the report for the rare processes related to our topic here.

175
00:22:53.520 --> 00:22:55.320
stefania gori: So let me share this screen.

176
00:23:03.150 --> 00:23:04.440
stefania gori: Can you see my my screen.

177
00:23:04.950 --> 00:23:07.530
Albert De Roeck: looks all good to be here you you're ready to go.

178
00:23:08.160 --> 00:23:08.820
stefania gori: Okay, great.

179
00:23:09.390 --> 00:23:21.330
stefania gori: yeah so sore thanks for inviting me this is going to be a summary of the opportunities that are in the context of lonely particle so today our processes from PS no master from here.

180
00:23:22.530 --> 00:23:40.710
stefania gori: So just a little bit of presentation of it from here on, so here, you can see the frontier convenience and in this frontier we have several topical groups that are listed here, and then you can find also the corresponding topical convenience.

181
00:23:41.730 --> 00:23:50.730
stefania gori: As you can see, there are many different type of topics that are covered by these frontier, in particular, you can see, on similar topics normal workflow physics lab.

182
00:23:51.270 --> 00:24:02.790
stefania gori: flower physics, as well as testing fundamental physics, in a small experiments as well as the acceptor set high intensities and for the stork and for the purpose of this work so.

183
00:24:03.780 --> 00:24:15.180
stefania gori: i'm going to to focus on Lisa rfc so that i'm combining with Mike Williams and so just a little bit of detail on this topic or group.

184
00:24:18.210 --> 00:24:25.290
stefania gori: So here, you can find the Samsung contacts, so we have our web web pages like Channel and the mini Lisa.

185
00:24:26.160 --> 00:24:35.970
stefania gori: What is the goal, the goal is to achieve a broader theoretical and experimental exploration of the physics of acceptance, and these are the sectors that are at or below the gv scale.

186
00:24:36.480 --> 00:24:52.740
stefania gori: Okay, so this is sort of complimentary towards the sign on discussed for the energy frontier, so we want to study back sectors, both from the theory want to be an experiment, are going to be also we studied the set of benchmarks and with a with a do.

187
00:24:53.760 --> 00:25:04.350
stefania gori: Covering as comprehensively as possible interesting signatures that we can we want to search for at high intensity experiments and then there is the.

188
00:25:04.740 --> 00:25:20.670
stefania gori: The experiment paddler study, so they study of the experiments that can come from today physics offer duck sectors and as we've seen day in becoming slides I have six involves experiments from small to large and from dedicated to multiple okay.

189
00:25:21.810 --> 00:25:23.220
stefania gori: And i'm.

190
00:25:24.630 --> 00:25:32.160
stefania gori: In terms of of white papers that we have prepared so last March, it was the deadline for.

191
00:25:33.600 --> 00:25:47.790
stefania gori: For White Paper so so we receive it and we we received several contributed the White Papers and now we are working and finalizing our final report and this report these organized around the science course and then questions.

192
00:25:49.350 --> 00:26:03.510
stefania gori: Trying to really give an overview of all these contributions that we have received the last March, and to organize our work around the science questions we have.

193
00:26:06.150 --> 00:26:07.230
stefania gori: We have divided.

194
00:26:08.910 --> 00:26:13.680
stefania gori: The physics in these three big ideas questions.

195
00:26:14.730 --> 00:26:22.890
stefania gori: So the first big idea is really focus on the back matter, so the idea is to detector that market particle production, with a focus on.

196
00:26:23.400 --> 00:26:31.320
stefania gori: sandwich targets and here you can see it towards the second question is how to explore the structure that acceptor.

197
00:26:32.160 --> 00:26:44.970
stefania gori: By producing and detecting unstable that party person with a focus on mini on person interactions and then, finally, the third The big question is what happens if we go beyond the meaning marla modern, since we have.

198
00:26:45.990 --> 00:26:50.280
stefania gori: Each flower structured or Internet age structure of the Doc Center.

199
00:26:51.300 --> 00:27:06.780
stefania gori: And then, finally, we have a fourth sorry to be solicited White Paper that is focused on summarizing or the several experiments in facilities, they contribute to our understanding of the physics or duck sectors and now in each of these big idea.

200
00:27:08.400 --> 00:27:14.160
stefania gori: We have discussion of the physics, along with particles that's why I also use these.

201
00:27:15.240 --> 00:27:27.480
stefania gori: All these are three by three big ideas and so in the following slide what we do is to give you an overview of the summer activities with this special focus on long article.

202
00:27:29.040 --> 00:27:40.650
stefania gori: um so first of all our our in our f6 report will highlight the motivations for that sector at today Jimmy scale and below.

203
00:27:41.490 --> 00:27:48.060
stefania gori: And, especially in the context or lonely particles, as always, we all know, we have a strong motivation coming from that matter.

204
00:27:48.840 --> 00:28:00.900
stefania gori: The reason being that, if we want to have a dark matter candidate below the computer at scale and we need to have that sector so so that monster need to leave in its own accepted that.

205
00:28:02.130 --> 00:28:12.180
stefania gori: can be populated by many additional particles that are not charged under the summary modification cemeteries and there is on these that if we want to have a family that matter.

206
00:28:12.930 --> 00:28:31.170
stefania gori: we've actually come on abandons, we need to have a new light the mediator that efficiently depleted the that matter abundance in such a way to attain that I already abundance and these mediator, sometimes can be long leave that we have is late, about the longer you are mediators.

207
00:28:32.310 --> 00:28:46.950
stefania gori: This is, of course, not the only motivation, we have several other motivation some coming from extended that matter models will have an example of these, it will be reported in our head of six reporter so excited that Marty Melissa.

208
00:28:48.360 --> 00:28:57.810
stefania gori: can naturally put a video to the presence of long lived excited that the States and then we have a set of additional motivations beyond the dark matter.

209
00:28:59.070 --> 00:29:05.250
stefania gori: Long we've accepted particles can address said, are the anomalies in data, including humans to.

210
00:29:05.850 --> 00:29:22.890
stefania gori: and many other motivations are some coming from nuclear physics so neutrino mouse model building the pineal antibody and seemingly the song CP problem so many of these models are of the models that address these problems, look at the light normally articles, so this is.

211
00:29:24.720 --> 00:29:33.600
stefania gori: The part of the motivational that is contained in our direct six report and then we have apart the dedicated to experiments.

212
00:29:35.970 --> 00:29:42.120
stefania gori: And we'll get the flower of the experiments that we discuss about the just is like to summarize it all up.

213
00:29:42.540 --> 00:29:48.060
stefania gori: So, in spite of the fact that we have a we're discussing many experiments the experimental techniques and only three.

214
00:29:48.720 --> 00:30:01.110
stefania gori: And this has been inspired by some work that we have done already, few years ago, four years ago, in the context of the basic research needs for that matters more projects new initiative for that also supported by the way.

215
00:30:02.220 --> 00:30:09.480
stefania gori: So here, you can see, the first two techniques that are focused particularly on the production of that market.

216
00:30:10.680 --> 00:30:21.990
stefania gori: So the first technique is a social meeting energy momentum so that is to produce, for example, at the pizza gate experiments it doesn't matter state or in Germany visible state.

217
00:30:22.620 --> 00:30:31.350
stefania gori: That will affect the the the initial beam, so we are, we will look for a meeting and he momentum, and then we can conclude.

218
00:30:31.980 --> 00:30:43.590
stefania gori: Maybe that we have produced some that matter of data Center state another to be another technique is to look for a risk happening, so we are producing that matter to them the risk Catherine in our.

219
00:30:44.700 --> 00:30:53.940
stefania gori: The title that is placed on after the target, and this is the particularly the case of nutrient experiments as will hear later during the next book.

220
00:30:54.930 --> 00:31:02.490
stefania gori: And then we have the third the technique, so the third technique is focused on a certain point and stable that separate article.

221
00:31:03.120 --> 00:31:18.240
stefania gori: And, in particular, we want to look for these Ebola on the key products and then for there, so they stopped we focus on these third technique, because this is a technique that we are going to use to search in dimensionally discover lobby particles okay.

222
00:31:19.770 --> 00:31:29.460
stefania gori: um now in terms of little bit more about the experiments, so the experiments that we discuss our older high intensity experiments.

223
00:31:30.330 --> 00:31:42.540
stefania gori: In the company so long, the particles will have on one side being dumped experiments, you can see here, and the idea is to have a high intensity beam so these can be electron beams.

224
00:31:43.260 --> 00:31:55.710
stefania gori: positron beams causes a problem beings or young beams and then we have a target, followed by a Dom and they do, they don't is that they don't be shielded.

225
00:31:56.760 --> 00:32:06.840
stefania gori: from some DEMO that ideation so most of the summer model particles will be blocked here the dump in fact that the same type of experiments are supposed to be quite the no background.

226
00:32:07.590 --> 00:32:16.800
stefania gori: And then, if we have the production of that matter or accept the status the stock market we propagate through through the dark into through the dump.

227
00:32:17.310 --> 00:32:27.060
stefania gori: And then, if we have it accept or State that is unstable long leaves eventually can be after the dump and then we can look for a decay products, here in this the data.

228
00:32:29.610 --> 00:32:36.630
stefania gori: We have several experiments without or ld Skype with already running and some other proposals that are for the future.

229
00:32:38.400 --> 00:32:45.240
stefania gori: complimentary to be number experiments, we have our factories i'm flower factories and have.

230
00:32:46.200 --> 00:33:04.500
stefania gori: exploited differently detection strategies strategy for a long the particles, in particular, the idea is to detect unstable dexedrine particles that are produced from Muslim the case and we are selling clever factories at the different.

231
00:33:05.580 --> 00:33:25.140
stefania gori: facilities, so we are studying the factories can Patrice as well as by and populism Okay, so these very briefly, are all experiments that we are studying in the context of longleat particles and then we have several additional experiments in the context of detection of backmarker.

232
00:33:27.330 --> 00:33:35.430
stefania gori: We are working on a table like this, so this is the preliminary, but this is supposed to summarize all the experimental effort.

233
00:33:36.960 --> 00:33:38.850
stefania gori: In our group.

234
00:33:40.380 --> 00:33:46.440
stefania gori: As you can see the experiments are divided in the US experiments, so that you can find here above this line.

235
00:33:47.640 --> 00:33:57.060
stefania gori: And then experiments that are international some of them with a significant US contribution, then here in this line here, so you can see the the timeline.

236
00:33:57.570 --> 00:34:17.820
stefania gori: So here is now the President, and you can see that there's some experiments already running now, this is the case as we'll discuss later or for the Beltway experiment, the ECB, the sexy at the factors that already signed on that described as well as any 64 some neutrino experiments.

237
00:34:18.870 --> 00:34:33.990
stefania gori: Some experience with London sona, this is the case of spin quest and that West and some are more for the for the future also what I want to highlight in this quite a visa cash tony's that we have several signatures that we look for and we should focus on this.

238
00:34:35.970 --> 00:34:48.090
stefania gori: portal daughter So these are the signatures involving along the particles and we see that the seminar law, these experiments can indeed the search for knowledge articles right.

239
00:34:50.160 --> 00:34:59.220
stefania gori: Okay, very good, so this is just an overview of of all the experiments and then, what are the signatures So these are the three main group of signatures.

240
00:34:59.700 --> 00:35:06.570
stefania gori: i'm sort of hiding ELISE will be the first one, because this is very much a dedicated to the documentary That was a little bit beyond the scope of this talk.

241
00:35:07.140 --> 00:35:15.240
stefania gori: And the hammer highlighting the second and third them type of signatures, because these are the signatures that can be used to look for long belief particles.

242
00:35:15.720 --> 00:35:23.040
stefania gori: So either we have the direct production or or, for example, immediately and that can be lonely and became back to this summer mala.

243
00:35:24.720 --> 00:35:44.370
stefania gori: order, we have a production or some dark cycle, particularly in the REACH that certain models and then we can add baby came back to summon mala but not only back to Somalia visible particles sequencers can involve also missing energy as well right.

244
00:35:47.160 --> 00:35:55.950
stefania gori: Now, in this second part of this awkward I will do is to report on the benchmark motors, that we have.

245
00:35:57.300 --> 00:36:04.410
stefania gori: chosen as a representative before our era rfc report because, of course, in this big idea.

246
00:36:04.830 --> 00:36:13.440
stefania gori: solicited White Papers, we have many blossom any benchmarks about that we had to make a decision, because indeed So what are the salmon was was mentioning.

247
00:36:14.310 --> 00:36:22.770
stefania gori: The rfc report, you need to be relatively short, because then that needs to be summarized by the address on file, so we had to make a choice.

248
00:36:23.310 --> 00:36:33.090
stefania gori: About benchmarks, so what i'm really part of the benchmarks that we have chosen and those that do contain all of these articles, so the first one is.

249
00:36:34.920 --> 00:36:45.570
stefania gori: a benchmark for a long lead mediator, we see the the doctor mediator, and this is coming from the big idea to solicited White Paper, then we have a benchmark.

250
00:36:46.680 --> 00:36:56.100
stefania gori: Coming from mothers that are motivated by anomalies any particular to Manchester, and this is coming from bigger the number three and then, finally, we have benchmarks coming.

251
00:36:56.610 --> 00:37:07.440
stefania gori: From reach docs actors in particular model so with exactly the back modesty right so let's start with the first one.

252
00:37:08.490 --> 00:37:20.880
stefania gori: Long leave the mediators, and so we have a minimal that water model so that problem is, we all know, communicates with us through the circuit city mixing operator.

253
00:37:22.080 --> 00:37:40.710
stefania gori: And then, if this is the full model on new physics, so we know that the Dakota communicate back to the standard model thanks to these media into this portal interaction and this is the somebody for me there's somebody plotter that is going to appear in our f6 report.

254
00:37:41.730 --> 00:37:56.310
stefania gori: So this is the preliminary so indeed if you have any comments, please let us know um and so angry, in general, you can see the parameter space that is already broke the bypass experiments.

255
00:37:57.030 --> 00:38:04.920
stefania gori: And then the several lines correspond to disagree, an experiment that we have studied the in the context of their seats snowmass group.

256
00:38:05.910 --> 00:38:24.240
stefania gori: and putting an arrow here, probably discuss the support will be actually cut the 10 GB or some to highlight really the the role of high intensity experiments and then at higher masses, we have all the energy frontier experiments.

257
00:38:25.380 --> 00:38:35.580
stefania gori: And below 10 GB Doc you can see, is what can be reached by collateral experiments, so you can see the bell to experiment here and delete CB.

258
00:38:37.350 --> 00:38:46.590
stefania gori: And, and then that here at blue and masses and smaller values of excellent now, you can see what we can reach using for the titles, as well as.

259
00:38:47.250 --> 00:39:01.290
stefania gori: Being dumper experiments either electron initiated the or proton initiated and then to guide the I am putting here by hand the liner for the lifetime of the Doc photo not have one centimeter.

260
00:39:02.370 --> 00:39:07.290
stefania gori: And we can see that, indeed, the if we look for longer than that photons we have.

261
00:39:07.950 --> 00:39:19.530
stefania gori: A quite important, and data be number experiments we play we play a very important role, covering a larger amount of parameters space that is not yet covered.

262
00:39:19.980 --> 00:39:30.630
stefania gori: And then there is a nice complementarity with other experiments like belt, will he be that can focus more on promptly leaking that programs right.

263
00:39:32.400 --> 00:39:33.360
stefania gori: So this is the first.

264
00:39:33.750 --> 00:39:35.700
Juliette Alimena: Three minutes left think the second.

265
00:39:36.000 --> 00:39:38.340
stefania gori: Okay, so this is the percentage of America.

266
00:39:38.430 --> 00:39:40.980
stefania gori: than the second benchmark, as I said, these focused on.

267
00:39:42.000 --> 00:39:43.560
stefania gori: He managed to motivated model.

268
00:39:44.640 --> 00:40:02.310
stefania gori: We have a flower specific that scale or that only couples to me on this is actually interesting enough, one of the few benchmarks that is still quite an explorer the for for a that particle we with a master at or below the GB scale.

269
00:40:03.330 --> 00:40:15.660
stefania gori: And so, this this scale we dictate to me on CDs have enough or two photons if it is below if it has a mask below the new threshold and and if so.

270
00:40:16.500 --> 00:40:30.570
stefania gori: The lifetime can be longer because the sticky is a loop suppressor again we have so many Plata for for the scenario that you can see here in grey again are the regions already broke the bypass experiments.

271
00:40:32.130 --> 00:40:45.330
stefania gori: In Green, you can see here the Germans two or three Donna, and then again, you can see the complaint, I have two different experiments, we have a high energy colliders as well, I said the law and mass we have been to.

272
00:40:45.930 --> 00:40:54.120
stefania gori: And the full for the scope of this of this talk, we should actually focus on masses below their damion threshold.

273
00:40:54.690 --> 00:41:08.520
stefania gori: Because indecision here the docs killer will become longer leader, and then we have been done experiments that you can pro, but these regional parameter space, as well as them you're missing momentum experiments tonight.

274
00:41:09.540 --> 00:41:18.930
stefania gori: And then, finally, the last the benchmark model that we are presenting our models, with the documentary excited state.

275
00:41:19.440 --> 00:41:31.020
stefania gori: So, since i'm running out of time, I will present only one out of the two models, so the model that i'm going to present a modest with the strongly interacting a massive particles or seems.

276
00:41:31.800 --> 00:41:38.880
stefania gori: So these can be realized in your city like theories, in which we have the baking or a large global symmetry.

277
00:41:39.900 --> 00:41:51.900
stefania gori: And the opinions of lighter clients, some of which can be dogmatic candidate and what is interesting when the smallest, so what I want to highlight is that there seems to be documented Eric abundances.

278
00:41:52.920 --> 00:42:02.640
stefania gori: seta by a three to one correlation, then the documentary mass that is heated by these models if we hold want to have a family rarely.

279
00:42:03.180 --> 00:42:13.200
stefania gori: Is it around the hundred and maybe, so this is back, but if you want for a high intensity experiments and in terms of signatures What is interesting is that.

280
00:42:13.800 --> 00:42:32.100
stefania gori: Since we have a darker you CD like theory, we have our society states like you know all the Muslims in KC D and some of these factors can be long naturally long lived and they can be produced by a that photo Mickey and they can.

281
00:42:33.150 --> 00:42:44.160
stefania gori: lead to displace the signatures that can be looked at the many experiments, including them being dumped experiments and then in here i'm presenting.

282
00:42:45.390 --> 00:43:04.500
stefania gori: The so many Plata for this type of mothers and you can see again the company mentality of where what we can do at the collider experiments in particular that are using is a model for signature and what we can do a brain dump experiments looking specifically for the.

283
00:43:06.240 --> 00:43:18.360
stefania gori: displace the decay of these that vector right and here are, in particular, high energy proton beam damper will cover an important role in.

284
00:43:19.230 --> 00:43:26.130
stefania gori: In each of these parameters space right, so this leads to my conclusions.

285
00:43:27.120 --> 00:43:36.630
stefania gori: So in this token wanted to give you first an overview of our our f6 activities that are in the context of social products that are particles that high intensities.

286
00:43:37.620 --> 00:43:44.130
stefania gori: Focusing on the surgery experimental techniques and then in the second part of the talk I focus on lonely.

287
00:43:44.850 --> 00:43:53.400
stefania gori: Particular benchmarks and, in particular, I wanted to show you that mean dump experiments on one side and clever spotter is, on the other side that can cover.

288
00:43:53.730 --> 00:44:04.710
stefania gori: A very important role in testing the parameter space of of of these types of models, and this is a crucial complementarity with the high energy colliders, as we have already heard.

289
00:44:05.100 --> 00:44:14.940
stefania gori: From Simon and auxiliary detectors and colliders as well as a new Tina experiment, and this will be the topic offer next next talk, thank you.

290
00:44:17.820 --> 00:44:27.480
Albert De Roeck: Thank you very much, defined for this very nice report very instructive and we opened that now for questions of course is already there.

291
00:44:28.050 --> 00:44:31.710
José Zurita: yeah, so I think if they find yeah I wanted to quickly ask to the dark.

292
00:44:31.710 --> 00:44:34.140
José Zurita: For the modern so you chose the minimum modern.

293
00:44:34.230 --> 00:44:41.610
José Zurita: But I think in that you know normally people also consider things like a towel by yourself, you or we might know sell that.

294
00:44:42.630 --> 00:44:48.060
José Zurita: booth booth have East flavor flavored stuff and you know processes, they could have an impact, so you know if.

295
00:44:48.060 --> 00:44:54.630
José Zurita: People somehow left out of your report or the past that email sent to powells group or how India being.

296
00:44:54.960 --> 00:45:03.330
stefania gori: yeah yeah so the mothers, since you mentioned do actually actually describe the me show you i'm.

297
00:45:04.770 --> 00:45:09.180
stefania gori: Merely in this big idea three So you see the White Paper.

298
00:45:11.640 --> 00:45:23.430
stefania gori: In our added six reporters so they plotted I showed, you are the plots data in our executive summary of the added six reporter, and then they are f6 report will have a section.

299
00:45:24.450 --> 00:45:37.020
stefania gori: So three sections one which dedicated to these are big ideas, so in this section for big idea number three will actually discuss also the models that you have that you have mentioned.

300
00:45:37.560 --> 00:45:44.100
stefania gori: So what I was reporting is the executive summary or rfc and then, of course, there we had to make it a choice.

301
00:45:45.660 --> 00:45:48.540
Albert De Roeck: Okay, thank you, thank you, Simon.

302
00:45:50.070 --> 00:45:55.440
Simon Knapen: All right, very nice I was just wondering, maybe I missed it on the big table, but are you also discussing.

303
00:45:56.790 --> 00:46:04.320
Simon Knapen: The heightened stimulus facilities like PSI and it immediately MAC and looks kind of experiments.

304
00:46:04.800 --> 00:46:09.240
stefania gori: And yeah so um let's see, so there is.

305
00:46:12.330 --> 00:46:18.210
stefania gori: There is so this meal facilities at the formula that have been proposed.

306
00:46:19.830 --> 00:46:24.000
stefania gori: So, in terms of the experiments that you mentioned, we don't have a shame.

307
00:46:25.740 --> 00:46:26.130
stefania gori: yeah.

308
00:46:27.300 --> 00:46:36.750
stefania gori: Within the receiving very much contributions, and we are going to mention them a little bitter, but we, we are not highlighting them too much in this context.

309
00:46:38.220 --> 00:46:38.580
stefania gori: yeah.

310
00:46:40.560 --> 00:46:41.370
Albert De Roeck: yeah Michael.

311
00:46:41.790 --> 00:46:52.050
stefania gori: I think sorry just to comment, a little bit more so, they will be mainly discussed here, let me show you so here, where I was given the overview of the rf.

312
00:46:53.100 --> 00:47:05.010
stefania gori: So there is a group that is dedicated to charge the lack of violation and the Ruby discussion or so dark sectors coming from mute we experiments and so on yeah.

313
00:47:07.560 --> 00:47:09.630
Albert De Roeck: Okay, like my boy.

314
00:47:10.830 --> 00:47:16.230
Michael Albrow: that's my 10 can you show it's like 10 again it's where, if you could please.

315
00:47:16.350 --> 00:47:16.710
stefania gori: grab.

316
00:47:16.830 --> 00:47:19.170
Michael Albrow: The facet proposal to this clock.

317
00:47:19.230 --> 00:47:22.890
stefania gori: Very good, thank you, yes, thanks, a lot definitely.

318
00:47:23.970 --> 00:47:31.110
stefania gori: In fact uh yeah, as I mentioned, when I when I was presenting these type of plots please let us know if.

319
00:47:32.220 --> 00:47:50.730
stefania gori: If we're missing something so this lady mean I plots that that I have been showing in my slides are all positive in our slack channel and their policy, they are because we, we want to have a feedback and if we are missing any queries please let us know as soon as possible.

320
00:47:51.480 --> 00:47:52.170
Michael Albrow: Right, thank you.

321
00:47:56.340 --> 00:47:57.540
Albert De Roeck: For the questions.

322
00:47:59.100 --> 00:48:11.730
Albert De Roeck: In fact, I see here on your plots you have ship, but you did not mention it on slide number seven or so is that it was not just all inclusive slide or it was.

323
00:48:12.870 --> 00:48:15.720
Albert De Roeck: For some reason that that was not there.

324
00:48:16.800 --> 00:48:29.280
Albert De Roeck: The reason i'm asking is that particularly you, of course, ship was not like selected for the last round in the European strategy, but it does have that, in the sense that.

325
00:48:30.300 --> 00:48:42.630
Albert De Roeck: In fact it, it will come back with with an alternative way of doing the beam dumb facility, which is much cheaper and they're gonna go for a second shot, but the the physics.

326
00:48:43.800 --> 00:48:47.220
Albert De Roeck: coverage is going to stay very much similar.

327
00:48:48.420 --> 00:48:55.050
Albert De Roeck: So what should not abandon it saying you know it's it's it's it's not it's not gonna happen, but you do have the curve so that's already good.

328
00:48:55.110 --> 00:48:55.980
stefania gori: Night right.

329
00:48:56.250 --> 00:49:06.810
Albert De Roeck: There was no no other reason why it's not there, so yeah that's right yeah you have all day she curves not only on the stock photo on plot about also in the other plots where we have.

330
00:49:07.230 --> 00:49:08.400
stefania gori: The corresponding shaped curve.

331
00:49:08.550 --> 00:49:14.640
Albert De Roeck: that's right do you still consider it a live ish in the document that that's good.

332
00:49:15.240 --> 00:49:33.180
Albert De Roeck: And also Simon said something that you did he taught he mentioned that he smells are also having intellectuals are also discussed in in your area probably didn't have time for this report, if you have the better, are they in your report.

333
00:49:33.510 --> 00:49:36.510
stefania gori: yeah absolutely so um so agent.

334
00:49:38.730 --> 00:49:52.980
stefania gori: Here in this big idea number two so, can you go to number two, we are discussing all minimal interaction so so we have a data problem portal, the dark skillet porter neutrino portal is, whereas the auction portal.

335
00:49:54.960 --> 00:50:09.780
stefania gori: So, all of them are here and they will be mentioned in our our at six report now the Plaza again the closer that that i've been showing you my plot the evening, my in my talk are coming from the audit six.

336
00:50:10.230 --> 00:50:14.100
stefania gori: executive summary data, then, will be reported in the rf.

337
00:50:15.210 --> 00:50:15.900
stefania gori: reporter.

338
00:50:16.410 --> 00:50:27.090
Albert De Roeck: Okay i'm asking, because we have a few new results which are in a report with it in the neutrino sector which we'll talk about in a second, or at least an hour mentioned tomorrow.

339
00:50:27.810 --> 00:50:35.340
Albert De Roeck: To make sure that the latest of these curves match with what we show should I contact Brian patella so best for that already.

340
00:50:35.400 --> 00:50:48.030
stefania gori: yeah absolutely absolutely and then Lisa so the best way since, as we got it from this discussion we have many flaws that are contained in this big idea So you see the White Papers, the best.

341
00:50:49.380 --> 00:50:55.170
stefania gori: The best way to contact us is through their slack channel that you can see here.

342
00:50:55.560 --> 00:51:09.180
stefania gori: And in this slack channel, you can see, on the presence of the solar city, the White Papers and if you have any comment on the on those White Papers, please contact the corresponding editor.

343
00:51:10.560 --> 00:51:29.100
stefania gori: So that's the best and quickest way to send us your comments on this, so you see the White Paper, and then they are at 630 reporter we let me summarize this White Paper so it's very, very important to send the comments on this on the search for the White Papers.

344
00:51:30.150 --> 00:51:38.460
Albert De Roeck: Right thanks Jay I see you have a question but, mind you you're The next speaker so if your question is too long we subtracted from your speaking time.

345
00:51:40.620 --> 00:51:41.070
Jaehoon Yu: Thank you.

346
00:51:42.450 --> 00:51:56.460
Jaehoon Yu: I just want to make you know similar comment about you know inclusion of tune in there, and since probably won't but hell is actually in leading one of the white top sub topic of white papers and enable three.

347
00:51:57.600 --> 00:52:05.760
Jaehoon Yu: I am presuming that all those plots and do limits are already reflected in these invited by papers, yes.

348
00:52:06.270 --> 00:52:15.330
stefania gori: Absolutely, yes, yes, definitely yeah and in fact I mean you, as you can see here I mean we are also reporting newness one of.

349
00:52:16.380 --> 00:52:22.860
stefania gori: Our experiment and there is a lot of complementarity and the new person will appear in our our clocks definitely.

350
00:52:23.550 --> 00:52:24.600
Jaehoon Yu: Right thanks.

351
00:52:25.770 --> 00:52:29.730
Albert De Roeck: Great great thanks to find here for this reports and.

352
00:52:31.500 --> 00:52:33.450
Albert De Roeck: Then we switch to Jane.

353
00:52:34.890 --> 00:52:38.580
Albert De Roeck: 4k report on the industrial sector of them during the frontier I should say.

354
00:52:39.330 --> 00:52:48.000
Jaehoon Yu: Right well well, thank you very much for inviting me but it's this report and thank you stephanie for leading me to write it my talk.

355
00:52:48.450 --> 00:52:58.920
Jaehoon Yu: So i'm going to talk about the neutrino frontier land piece that you Tina frontier i'm not going to go through, just like the other two speakers have done in the in the summary report itself.

356
00:52:59.580 --> 00:53:20.880
Jaehoon Yu: Instead i'm going to talk about you know the justification and why we can contemplate and, in doing psn fedex a neutrino experiment first and then i'll cover a few you know interesting topics that actually utilizes The case of these it's toxic particles or lps.

357
00:53:22.140 --> 00:53:27.480
Jaehoon Yu: In the dune detector and and to turn your tuner experiment.

358
00:53:29.280 --> 00:53:37.800
Jaehoon Yu: So um the the, as you all know, the new to new experiment political motivation is the flavor oscillation himself firmly established.

359
00:53:38.520 --> 00:53:53.190
Jaehoon Yu: By now, through you know late 90 through through now and happens because flavor in mass I guess these different so you know that probability of these oscillation is proportional to the mixing angle between the different.

360
00:53:53.850 --> 00:54:00.030
Jaehoon Yu: States and delta X squared minus the square of the methods and Oliver he knew.

361
00:54:01.170 --> 00:54:04.890
Jaehoon Yu: The baseline over the neutrino energy.

362
00:54:05.700 --> 00:54:17.070
Jaehoon Yu: And, and the neutrino sector, instead of moodle who you know which assumes that the new tuners have mad no mass and easy modification, because the speakers, by definition, the automation visa.

363
00:54:17.490 --> 00:54:24.750
Jaehoon Yu: is done to the masses so that requires concision measurement that the automation parameters that just mixing angle and mass hierarchy.

364
00:54:25.170 --> 00:54:36.750
Jaehoon Yu: And it's studying of the CP by an agent in neutrino sectors, which is already happening and the Cork sector and precise measurement of the CP CP page themselves.

365
00:54:37.470 --> 00:54:50.430
Jaehoon Yu: And, of course, then the next question is that these good lead to a new new symmetry and the question of the grand unification, the energy scale of the Grad unification and you know, including the discovery of the nuclear decay.

366
00:54:51.270 --> 00:55:05.490
Jaehoon Yu: You know and and and understanding the particles of astrophysical origin, such as the supernova neutrinos and black information is based on how the neutrinos are coming in and and running neutrinos and documentary.

367
00:55:06.750 --> 00:55:19.290
Jaehoon Yu: And these require high statistic samples and how do we get the highest that examples one large mass large volume detector with a highly capable detectors that can measure energy, as well as the tracks and momentum.

368
00:55:19.800 --> 00:55:33.270
Jaehoon Yu: and high intensity nutrient have been facility, which will generate large number of neutrinos with a lower baseline which is baseline just perfectly matching the neutrino oscillation prod prod probability.

369
00:55:34.350 --> 00:55:46.020
Jaehoon Yu: So, in the case of doing is doing stands for deep underground to experiment, as many of you already know it to you it's the US flagship no baseline you can experiment.

370
00:55:46.350 --> 00:55:54.060
Jaehoon Yu: baseline of 1300 kilometers which is located 1500 meter underground in an abandoned gold mine in South Dakota.

371
00:55:54.720 --> 00:56:05.130
Jaehoon Yu: And it uses very high is the proton beam starting starting out what with multiple two megawatt beam and capable of going up upgrading all the way to 2.4 megabytes.

372
00:56:05.700 --> 00:56:16.800
Jaehoon Yu: And these results in large numbers neutrinos is one of the conditions that I described before and it's great trade for the bs and fedex and you know percent search for the lps.

373
00:56:17.250 --> 00:56:26.220
Jaehoon Yu: The large mass detector at kiloton total for the killer connective mass it uses procedure may not look at our time production chamber.

374
00:56:26.910 --> 00:56:45.780
Jaehoon Yu: Which is the 3D imaging capability with loyalty threshold, you know, and this is one of the one of the real events of the nuclear destruction in the nuclear interactions and in our one of our prototype prototype detectors at CERN.

375
00:56:47.190 --> 00:57:02.160
Jaehoon Yu: And and we'd also is equipped with powerful procedure new detector complex to control systematics, but we also need to measurement, but these are actually providing the capability to do the meet the the bsm measurement.

376
00:57:02.610 --> 00:57:10.110
Jaehoon Yu: And this experiment was born in March 15 2015 as an international collaboration, this is only do four seven year old.

377
00:57:10.170 --> 00:57:18.030
Jaehoon Yu: Elementary schooler a TV station to large purple's also airbnb which exists in us and i've been over.

378
00:57:18.510 --> 00:57:32.070
Jaehoon Yu: In Europe, as a result of the 2013 us nomads Community strategy studies and now the collaboration is about 1400 people and over 200 students out of 33 countries.

379
00:57:32.640 --> 00:57:45.060
Jaehoon Yu: The anatomy of you do an experiment, as the typical neutrino experiment, you have been and beam is coming in here with the broadband between a beam from the 60 to 120 gv protons.

380
00:57:45.480 --> 00:58:01.290
Jaehoon Yu: and be power is going 1.2 megawatt 2.4, as you can see here a proton beam contain hits the target and 570 meters downstream, we have a new detector and we have about 200 meters of decay pipe which are now the pirates the decay.

381
00:58:01.710 --> 00:58:14.580
Jaehoon Yu: And this covers the area of the probability This shows the probability of oscillation probability of different kind of between species as a function of mutual energy for 1300 kilometers so we want to hit these two.

382
00:58:15.240 --> 00:58:25.140
Jaehoon Yu: You know oscillation maximum and that's what this is, you know beam line is capable of and and the beam then goes get shoot neutrinos flies down.

383
00:58:25.830 --> 00:58:36.450
Jaehoon Yu: On the ground for 300 kilometers to the South Dakota mind and the fire detector site here and is located 1500 a mirror on the ground, right here, where.

384
00:58:36.750 --> 00:58:52.440
Jaehoon Yu: You see, green is the new area that's up newly reactivated at this point, and at that point, we expect the film, you know we charge current interior interaction energy spectrum looks like this, which hits you know contains the two.

385
00:58:53.130 --> 00:59:01.170
Jaehoon Yu: automation maximum that indicated by these two arrows and these this cabin then contains four different cabins of.

386
00:59:01.500 --> 00:59:17.250
Jaehoon Yu: You know, for the for Christ that's that covers the 10 kiloton Nicaraguan each so do for adding up to 40 kilotons each one of these is 66 meters 15 meters by 15 meters so it's a large warehouse size detector.

387
00:59:17.880 --> 00:59:24.570
Jaehoon Yu: You know both cms and athletes and all these detectors are large, but these are probably even larger.

388
00:59:25.710 --> 00:59:35.280
Jaehoon Yu: The junior detect the complex is is the key for the bsm physics, you know, despite the fact that the fire detector also can do that, given the fact that the.

389
00:59:36.000 --> 00:59:54.750
Jaehoon Yu: The the flux, will reduce as we go down the detector location new tech is critical in terms of the PSA projects, the you know being clumsy in here from from the right to add the first detector that comes up is a bucket argon time project to Chamber which has the same target the new.

390
00:59:55.950 --> 01:00:02.760
Jaehoon Yu: Nuclear target as the fire detectors so that we can use it for minimizing the systematic uncertainties.

391
01:00:03.450 --> 01:00:17.670
Jaehoon Yu: We measured in eugene Oregon interactions and before accurate volume of 150 tons and we expect about 10 to the eighth immune neutrino charge current interaction is when the detector is on assets, which is about a hertz.

392
01:00:18.900 --> 01:00:27.810
Jaehoon Yu: Day it's followed by a large volume gas detector it's magnetized magnetized so that we can actually measure the momentum of the murals that's coming up.

393
01:00:28.110 --> 01:00:42.270
Jaehoon Yu: Out of the interactions happening in the liquid Oregon key PC, but it also provides a capability for us to do and search for the long new particle decays that are coming in and decaying and described it as I will show you later.

394
01:00:42.540 --> 01:00:50.100
Jaehoon Yu: This guest detector plays a crucial role in terms of searching for a moment particles, we expect about.

395
01:00:50.820 --> 01:01:02.100
Jaehoon Yu: 10 to the 6 million neutrino transparent interactions a year on access and do for this also provides a law background being detected technology for the.

396
01:01:02.790 --> 01:01:14.640
Jaehoon Yu: You understand that searches and these two upstream attackers are you know movable along the horizontal axis, so that we can measure the off axis angle and the neutrino.

397
01:01:15.360 --> 01:01:26.850
Jaehoon Yu: neutrino spectrum so, then we can see, we can make to the system we can reduce the systematics by measuring these different the neutrino spectrum.

398
01:01:28.380 --> 01:01:39.540
Jaehoon Yu: And, and the Finally, the the final detector is the sand, which is the system on about for on access neutrino detection which monitors on X neutrino beam flux, to the.

399
01:01:39.900 --> 01:01:50.700
Jaehoon Yu: detector which consists of a straw to tracker and the email it kept with 0.6 tesla magnet, and this also can also contribute to the searches for.

400
01:01:51.540 --> 01:02:00.420
Jaehoon Yu: The long the particles, such as behaving on laptops we actually have some studies using that now bsm you at neutrinos as I.

401
01:02:00.870 --> 01:02:15.930
Jaehoon Yu: said before we haven't even thought about doing any you know detailed psm studies in neutrino experiments, because having neutrinos themselves interact is is you know, even if that was a big issue.

402
01:02:16.920 --> 01:02:26.460
Jaehoon Yu: So the geneticists that the bsm end up you know pick up steam after 2013 us snowmass exercise, which you know which, after which the.

403
01:02:27.540 --> 01:02:33.360
Jaehoon Yu: P five science driver clearly list the strategic opportunities and at the same time, it says that.

404
01:02:33.990 --> 01:02:39.180
Jaehoon Yu: We must leverage the neutrino facility capabilities for precision precision automation measurement.

405
01:02:39.600 --> 01:02:59.820
Jaehoon Yu: To the next step, so this actually gave us an idea is that we can actually be able to use these these High Flux neutrino beam and proton beam zachary to to explore bsm fedex that wasn't there wasn't there before and also complimentary to those at the end for QA team.

406
01:03:01.020 --> 01:03:09.900
Jaehoon Yu: And and theory and experimental groups have been working together very closely and playing as he bought and we've been actually developing large amount of.

407
01:03:10.620 --> 01:03:18.000
Jaehoon Yu: The same topics that we can explore in this low energy kinetic energy and a paper on you know.

408
01:03:18.930 --> 01:03:24.300
Jaehoon Yu: report on progress in projects covered some of those opportunities here is the link.

409
01:03:24.960 --> 01:03:35.280
Jaehoon Yu: Which is an outcome of the first workshop at the University of Texas arlington April 2019 second on what happened because the pandemic and this year February 2022.

410
01:03:36.210 --> 01:03:49.860
Jaehoon Yu: You know, but the this actually resulted in you know summarizing six White Papers that Commission, which I will describe shortly third one will be at slack and next March and the announcements will follow shortly.

411
01:03:51.030 --> 01:04:02.370
Jaehoon Yu: So just to flash this, if you look at the science driver for the new frontier after 2013 snowmass exercise then neutrino frontier is you know.

412
01:04:03.150 --> 01:04:16.440
Jaehoon Yu: Port forwarding the six questions that are all based on which you know aspirations, what is missing the missing is the exploration of bs and physics at this particular time utilizing them up, you know consulting.

413
01:04:17.610 --> 01:04:26.370
Jaehoon Yu: Now, if you look into this bs and mutual signature Catholic priest, and there are one direct observation signatures which requires high influx.

414
01:04:26.760 --> 01:04:38.430
Jaehoon Yu: High influx and sufficiently large mass for scattering signatures and large volume for the case signatures and and then inferred all of the observational signatures from.

415
01:04:39.030 --> 01:04:49.560
Jaehoon Yu: Both beam and customer journey choices so leverage awesome bakery behaviors, such as the history neutrino searches and large target mess architected for the interactions.

416
01:04:50.850 --> 01:04:58.560
Jaehoon Yu: What do we need to know for these, we need to know this particular flux and the realistic behaviors and the detector that was that we need to have tools to do this.

417
01:04:58.830 --> 01:05:14.040
Jaehoon Yu: And we also need to know the neutrino flops and their interactions factor, because they become background to to the DSM signatures so some of the bsm physics topics and utility experiments, you know, or you know, taking.

418
01:05:15.630 --> 01:05:22.440
Jaehoon Yu: The new tech for new detector searches, so we take advantage of high be power it see that low mass dark matter.

419
01:05:23.010 --> 01:05:28.170
Jaehoon Yu: You know, having you to left on factor in like particles and large number of toxic particles.

420
01:05:28.500 --> 01:05:45.540
Jaehoon Yu: And also, you know fire detector searches, which take advantage of new new detector and large volume fire detector as well, and you can see that there are often a three behaviors and at the same time utilizing and detecting the customer journey, you know origin dark matters, for instance.

421
01:05:46.710 --> 01:05:54.330
Jaehoon Yu: So um you know these promote strong collaboration between theorist and incrementalist as as I think you know with the case and the.

422
01:05:55.140 --> 01:06:09.840
Jaehoon Yu: collide experiment as well once I started out, and this was all included in the technical design report of the June, and these topics are covered, and as a separate paper published paper and PTC.

423
01:06:10.860 --> 01:06:23.100
Jaehoon Yu: 2021 so these you know what I so called here are the ones that actually includes directs the K K signatures and of those I will just cover these three in in my talk.

424
01:06:23.910 --> 01:06:46.020
Jaehoon Yu: So now, before I go into cover that so the sub topic a group there are six top of the books within the bsm Katrina Katrina frontier topics copter frontier, which is an equal three and the we have there were some hundred and 40 some Li submitted have 10 split them into six different.

425
01:06:47.310 --> 01:06:54.060
Jaehoon Yu: categories, and these are in some sense the embodied White Papers and these invited white papers are coordinated by.

426
01:06:54.300 --> 01:07:07.470
Jaehoon Yu: You know combination of theories to an instrumentalist for all these different topics and the ones that that is so cool I know mark them are ones that has a direct note on the particle to 10.

427
01:07:08.850 --> 01:07:20.880
Jaehoon Yu: and a half or three summary report, you know, have been already gone through one round of comments and and they will then you know go through again, for you know before the final set of comments of.

428
01:07:21.420 --> 01:07:31.440
Jaehoon Yu: solace the final several comment comment this table is a table of the currently available topics that is covered in the nfl three and with.

429
01:07:31.860 --> 01:07:42.450
Jaehoon Yu: With you know sources and example experiments it's because there are so many different experiments that can explore this kind of topics we just provide a few you know handful of these experiments.

430
01:07:42.870 --> 01:07:54.030
Jaehoon Yu: For each of these topics, and please go through and look at it and see if we have missed anything if that was the case, then, then please pointed out to us this is included in our summary report.

431
01:07:54.810 --> 01:08:06.630
Jaehoon Yu: And the details are in the indie invited White Papers, just to remember that we decided not to include this all the experiments, because this is just just too difficult to do so.

432
01:08:08.040 --> 01:08:18.420
Jaehoon Yu: So now, let me just cover a few topics so first we start with the heavy you to Latin searches, you know June md or you know any new detector.

433
01:08:19.110 --> 01:08:30.060
Jaehoon Yu: You know even hyper can you could technically do this, although you know doing ND will provide a lot stronger signatures for these so these high intensity proton beams for these having you two letters.

434
01:08:30.480 --> 01:08:37.140
Jaehoon Yu: You know from the case of heavy metals such as piece of so he metals and the neutrino production target.

435
01:08:37.500 --> 01:08:48.450
Jaehoon Yu: And, and these are complimentary to colliders and the search area is is you know, in the normal range and html then decay to charge leptons and.

436
01:08:48.960 --> 01:09:01.170
Jaehoon Yu: You can see here and lighter measurements in de de de de niro to take a complex and and so, resulting in a charge leptons plus Amazon or two charges Latin plus neutrino final states.

437
01:09:01.620 --> 01:09:08.550
Jaehoon Yu: And you know vertex requirements would be very helpful in terms of identifying these and, of course, and minimize the background as well.

438
01:09:09.030 --> 01:09:16.260
Jaehoon Yu: and multiple production and decay channels are available i'm discovering a few you know tab for here, but there are four lot more.

439
01:09:16.980 --> 01:09:31.740
Jaehoon Yu: That you can actually find in this paper and albert's talk tomorrow to to find out more detail but complementarity, you can see here in this bread box area is the area that's covered by the Energy for interior experiments and collage.

440
01:09:32.670 --> 01:09:50.880
Jaehoon Yu: Whereas here, you can see that the new the defects our experiment for the electric coupling dominant case and the moon coupling dominant the case in both cases, these YouTube experiments cover the low mid range, that is a little difficult cover with the collaborative service.

441
01:09:52.110 --> 01:09:53.130
Men and yes.

442
01:09:54.660 --> 01:09:56.310
Jaehoon Yu: Thanks so okay.

443
01:09:56.670 --> 01:10:04.290
Jaehoon Yu: don't know if I can do three minutes i'll go fast okay so um hi teacher will be introduced large number of photons from brand and thread.

444
01:10:04.710 --> 01:10:17.340
Jaehoon Yu: And and neutral method, the case which makes it possible to contemplate a coupling of new you want gauge to standard model gamma is, and if you can see here, and I think this was already covered instantaneous talk.

445
01:10:18.000 --> 01:10:27.360
Jaehoon Yu: But in any case of give it result in the dark kind of potential document or particles in the final state or, for instance it's pretty pretty mcauliffe state.

446
01:10:28.680 --> 01:10:42.120
Jaehoon Yu: process would give us an accent like particles as well and detection is done through an electron or do korea's nuclear recoil wanted to gamma final stage, depending on what the toxic report we're looking for.

447
01:10:42.630 --> 01:10:54.390
Jaehoon Yu: So I cover this in this talk the aarp so you said you experiments in the production and the target is going through the you know photon and buyer the printer called process.

448
01:10:55.020 --> 01:11:02.490
Jaehoon Yu: And detection is like this, and this is the scattering case and we can also look forward to decay of the two fourth and final state.

449
01:11:02.820 --> 01:11:11.580
Jaehoon Yu: Of course, the background would be you know all dominant background would be from the neutrino interactions and nutrient interactions in the region that is very difficult.

450
01:11:12.090 --> 01:11:21.390
Jaehoon Yu: For us to you know nail down the uncertainties So what do you see here is the you know coupling of G gamma to to the math of the.

451
01:11:22.680 --> 01:11:29.760
Jaehoon Yu: The accident like particle and you can see that that you know, based on a study that you do like you know.

452
01:11:30.480 --> 01:11:46.980
Jaehoon Yu: Gas detector and and can cover the decay and the liquid org and they can cover the scattering and which can have the potential to cover the closed closed and cosmic trying there, and this is covered in this particular prl.

453
01:11:48.210 --> 01:11:55.740
Jaehoon Yu: And of course Doc 14 surgeries that was already discussed in previous talks and look at the various final stage we plus C minus.

454
01:11:56.790 --> 01:12:01.080
Jaehoon Yu: Plus minus five states which have a different kind of background contributions to it.

455
01:12:01.410 --> 01:12:12.600
Jaehoon Yu: And you can see we're covering in a very smaller energy range, then what was shown in the in the previous talk and, and this is a complementarity that that that you know.

456
01:12:12.990 --> 01:12:20.190
Jaehoon Yu: When you're trying to expand provide, but these are you know the the Loyalists racial then precision understanding of the neutrino.

457
01:12:20.910 --> 01:12:29.220
Jaehoon Yu: cause elastic and resonances to be essential for these things so here is a table of you know, the processes.

458
01:12:29.580 --> 01:12:46.440
Jaehoon Yu: That SDK that includes the case and signatures and potential backgrounds and, as you can see potential background is already closed and primary dominated by to neutrino interaction is YouTube nucleus interactions as the primary background.

459
01:12:47.310 --> 01:12:54.960
Jaehoon Yu: Now, therefore, these you know if you see this plot, and this is showing that these two arrows are the two areas that i've.

460
01:12:55.320 --> 01:13:06.870
Jaehoon Yu: i've mentioned before the the automation maxima and the energy range of the of the do an experiment or these oscillations experiments are in the range that is completely covered by.

461
01:13:07.200 --> 01:13:18.390
Jaehoon Yu: His low energy processes course I understand the resonance processes and and there are large uncertainties for neutrino nucleus cross section calculation so it's important for us to.

462
01:13:18.810 --> 01:13:30.690
Jaehoon Yu: For us to you know net nail down decent certain pci because you know any fluctuations in the standard model background is going to be the ones that that will you know mimic these.

463
01:13:31.830 --> 01:13:44.580
Jaehoon Yu: These is the psm signatures so collaboration between you know nuclear physics and highly fedex communities are essential in order for us to do a nail down these things well and I know that there are many.

464
01:13:45.150 --> 01:13:54.240
Jaehoon Yu: efforts of that and, of course, you know, the question is all in details right llp production it's extremely rare and are in the talents, that the.

465
01:13:54.540 --> 01:14:03.690
Jaehoon Yu: Standard more prophecy can easily be mass mass bystanders more applications, and this is the case for even for the collider experiments as well.

466
01:14:04.320 --> 01:14:09.510
Jaehoon Yu: And many theoretical different theoretical prediction generators for the new to nuclear.

467
01:14:09.840 --> 01:14:20.400
Jaehoon Yu: Nuclear interactions i've been in existence and continue improving, but they still have sizable intensities within one model and one generator and you know between.

468
01:14:20.880 --> 01:14:33.300
Jaehoon Yu: themselves well it's very important for us to significantly reducing uncertainties for critical it's critical for the bread and butter automation projects which is again beyond the standard model, but it is.

469
01:14:33.810 --> 01:14:39.360
Jaehoon Yu: You know, absolutely essential for estimating the background to llp searches are being censored.

470
01:14:40.230 --> 01:14:46.620
Jaehoon Yu: and generates the generous begin to incorporate llp process, but you know we could take a long time.

471
01:14:47.160 --> 01:14:54.180
Jaehoon Yu: To implement because of the insufficient resources or those people were working on seem to be you know a few people operation.

472
01:14:54.630 --> 01:15:04.050
Jaehoon Yu: And we need to further strengthen this effort and and for strong collaboration between generated teams and the experiments is a way of doing it.

473
01:15:04.590 --> 01:15:14.820
Jaehoon Yu: mitigating the limited resources and neutrino again nuclear physics and highly Defense communities must work together to understand you know the process.

474
01:15:15.180 --> 01:15:22.530
Jaehoon Yu: And, and we need more concerted effort and get them done in a timely fashion, these are all included in our report as well.

475
01:15:23.280 --> 01:15:30.660
Jaehoon Yu: So to conclude heightens the accelerator provides great opportunity, so for the lps as a signature for.

476
01:15:31.020 --> 01:15:41.880
Jaehoon Yu: them and that's at the particles high power proton beams for next generation and return experiments enable expanding fedex reach beyond that of the neutrinos and the standard model.

477
01:15:42.600 --> 01:15:56.190
Jaehoon Yu: The large scale large procedure in detecting such as dune capable of searching for you know Ellen peace and cover broad scope of a PSA projects and there has been logged interest and it's been growing.

478
01:15:57.030 --> 01:16:07.740
Jaehoon Yu: Throughout the past, you know, several years when we started out 2013 there weren't too many, and now there are a large number of papers, you can find an archive every day.

479
01:16:08.310 --> 01:16:15.600
Jaehoon Yu: And neutrino nuclear interactions are critical backwards Philippines and other PSA projects at the law kinematic face face.

480
01:16:15.930 --> 01:16:28.770
Jaehoon Yu: And it's rather than which is relevant to the neutral experiment and for improving this nuclear model is essential and that requires a close collaboration between the critics and height the physics community.

481
01:16:29.490 --> 01:16:38.730
Jaehoon Yu: And lps and the digital frontier a compliment that of the energy frontier, and we have ample up or two opportunities to further develop psm topics.

482
01:16:39.480 --> 01:16:46.410
Jaehoon Yu: That that can be explored in both frontiers and leverage search strategies and techniques collaboratively.

483
01:16:46.860 --> 01:17:02.310
Jaehoon Yu: Finally, so this is the you know what you saw and previously, and we have, at least in new tuna for you as far as I know, we have agreed to add one more question here, what are the psn signatures accessible to experiments, thank you.

484
01:17:04.110 --> 01:17:19.020
Albert De Roeck: Thank you very much a for very nice and quick tour into the retreat or world and how it connects up with with the things particularly interested by the people in this workshop Mike so you have a question.

485
01:17:19.110 --> 01:17:24.510
Michael Albrow: yeah so the target of course is made to make pies errors and pie pie chart pies in case.

486
01:17:25.140 --> 01:17:34.950
Michael Albrow: Has any of the White Papers proposing to increase the thickness of the target to kill those like neutrinos but without without actually enhancing town neutrino flux.

487
01:17:35.430 --> 01:17:50.700
Michael Albrow: and enhancing the particle production so even a month, even a few months to three months of that would make a very sensitive nop search, I mean the universe is much higher than he so.

488
01:17:50.760 --> 01:18:03.900
Jaehoon Yu: No, no, no mikey mikey right, so they are you are, you know I didn't cover it here but, but this these White Papers also cover high energy options, so that you know we can explore the town neutrino.

489
01:18:04.620 --> 01:18:15.780
Jaehoon Yu: regime as well, and that includes you know the variations of target and probably some level of freedom of the optimization of the Horn as well.

490
01:18:16.470 --> 01:18:30.300
Jaehoon Yu: and on top of that, we also have a new idea that came up, which is you know running running target list me for a few months and and and the study will be you know put on archive soon.

491
01:18:30.870 --> 01:18:52.320
Jaehoon Yu: And that seemed to be you know if you even if you reduce the intensity of the beam to say, for example, 0.6 megawatt instead of 1.2 megawatt by running it for three three to six months, you could actually explore large areas of you know, for instance lps or.

492
01:18:53.730 --> 01:18:55.140
Jaehoon Yu: Lomas dark matter I.

493
01:18:55.290 --> 01:18:56.370
Jaehoon Yu: guess mid paced.

494
01:18:56.370 --> 01:18:59.460
Albert De Roeck: basis, your last chance today.

495
01:19:01.860 --> 01:19:02.250
Jaehoon Yu: Yes.

496
01:19:04.110 --> 01:19:04.410
Okay.

497
01:19:06.090 --> 01:19:08.190
Albert De Roeck: yeah you, you still hear me right.

498
01:19:08.670 --> 01:19:08.910
yeah.

499
01:19:09.990 --> 01:19:17.250
Albert De Roeck: I was just checking it on more questions I think not, we also cross seven o'clock, so I think.

500
01:19:18.360 --> 01:19:27.180
Albert De Roeck: In Europe it's getting late thanks again Jay and also for all your efforts, because you're really one of the drivers for that sounds driver.

501
01:19:28.050 --> 01:19:36.060
Albert De Roeck: With all your initiative and also things you've done before, and besides, some of these things, most people perhaps focused on doing what you mentioned but.

502
01:19:36.360 --> 01:19:44.550
Albert De Roeck: Some of these studies will actually get dress rehearsals with the, for example, the short baseline at.

503
01:19:45.450 --> 01:19:56.460
Albert De Roeck: fermilab now, which is somewhat lower energy, but some of these things like for like dark matter, so we will already do these studies there and use these detectors which are like in the detector.

504
01:19:57.780 --> 01:19:59.430
Albert De Roeck: For actually exploring that.

505
01:20:00.060 --> 01:20:08.670
Jaehoon Yu: Right, I mean, so you know if I just add a little bit, first of all, thank you very much good words but but, but you know now.

506
01:20:09.360 --> 01:20:18.180
Jaehoon Yu: The existing experiments are also you know, using their their data existing data for each this microbe using existing data to.

507
01:20:18.510 --> 01:20:30.420
Jaehoon Yu: to explore these different DSM topics which we didn't you know even look into before now or these different ideas available, they are already starting to eat into some of the sensitivity space.

508
01:20:32.160 --> 01:20:34.590
Albert De Roeck: Okay, nothing but the good news.

509
01:20:35.700 --> 01:20:37.440
Albert De Roeck: All right, if there are no.

510
01:20:39.540 --> 01:20:40.830
Albert De Roeck: Questions or comments.

511
01:20:40.860 --> 01:20:49.290
Albert De Roeck: Then I would say, thanks everybody for staying with us and we'll be back tomorrow too, and thanks to all speakers for the session.

512
01:20:50.460 --> 01:20:52.020
Jaehoon Yu: Thanks My guess by.

513
01:20:52.350 --> 01:20:58.020
Juliette Alimena: Tomorrow we can continue with some of the themes developed here, namely have usual leptons.

514
01:20:58.020 --> 01:20:59.940
Juliette Alimena: And feature colliders thanks.

515
01:21:01.140 --> 01:21:02.430
Jaehoon Yu: Joe okay bye bye.
