Albert De Roeck: Western surfing, and now we're even recording it, and so we have a number of talks that context here.
Albert De Roeck: So the first dog is by revenue, as we saw and or, as we already discussed within he's going to talk about some predictions for the FCC ah ah, so you can share your screen, please.
Wei Liu-Nanjing University of Science and Technology: Okay.
Wei Liu-Nanjing University of Science and Technology: Can you see my screen, now we.
Wei Liu-Nanjing University of Science and Technology: Do okay.
Wei Liu-Nanjing University of Science and Technology: So shy starts.
Albert De Roeck: at full screen, it took a really well so been you're you're all set.
Wei Liu-Nanjing University of Science and Technology: So then, it says limitation and ready to ask you to talk and.
Wei Liu-Nanjing University of Science and Technology: has washed out our Community so i'm awaiting from the University of Science and knowledge and today i'm going to talk about handling treating us as as associations, no one can our model.
Wei Liu-Nanjing University of Science and Technology: So this talk is million based on payroll is just published FDR did an hour to send my father is such as our car can the end friend devilish okay so let's start with neutrino mass, we all know that to the finals and neutrino mass.
Wei Liu-Nanjing University of Science and Technology: Is a neutrino observations pyramid is a great breakthrough in particle physics, because it went are set.
Wei Liu-Nanjing University of Science and Technology: As a standard oil is not complete, because send them or does not pretty nutritional Mises.
Wei Liu-Nanjing University of Science and Technology: And, but not only that we find is that tryna wise it's really tiny you only have ED or neutrino but as a firm you Alice Hello naveed so 06 management gap user.
Wei Liu-Nanjing University of Science and Technology: and also the neutrinos as only neutral for meals, so we might help question Okay, maybe the neutrinos have different region or masses.
Wei Liu-Nanjing University of Science and Technology: So now we can review that's Okay, what are the mass mechanism in the standard model means.
Wei Liu-Nanjing University of Science and Technology: So I think in general engage a series, we have two kinds of mass mass mechanism so first one is Iraq, I must turn this is very general, so you have a Left and Right, for me, always.
Wei Liu-Nanjing University of Science and Technology: A hicks and always also someone from your head is kinds of mass term but also it is one right hand for me is is on any particular so it must be on neutral from you say can.
Wei Liu-Nanjing University of Science and Technology: cuz This is my one mass is mastering.
Wei Liu-Nanjing University of Science and Technology: So we so since you're on the line so how's this problem if a certain material have as this as a sample pipe has is derived mass terms, so we find one race trends in a sentence or.
Wei Liu-Nanjing University of Science and Technology: As you call company is going to be very small it's because that material mass is very small, so easy but we knew how his uh his potential make 287 color is more and we don't like that you think is unnatural everything air recovered shoot how.
Wei Liu-Nanjing University of Science and Technology: The senior manager collections auto one for ideal.
Wei Liu-Nanjing University of Science and Technology: So now we want to fix it so One possibility is that it was a neutrino mass I introduced by both of them, so we have how these kinds on a mass matrix.
Wei Liu-Nanjing University of Science and Technology: So it's a zero MB MB Mr, so this is so called the system, you can ISM is because, when it dies in this matrix your how to market, it says sort of the first one is going to be.
Wei Liu-Nanjing University of Science and Technology: inversely proportional to the second one so since we windows and the first month is, it is very timely, so we can we need another very happy mass audiences, so we call this first one so lightly trina was the second one so having triple.
Wei Liu-Nanjing University of Science and Technology: Zero for evil we missing this Mr so my wife and my son to be very happy we can still making this direct mass to be like, although TV, which means, as you call a copy paste natural again.
Wei Liu-Nanjing University of Science and Technology: So it's as we can and natural explains autonomy is absurd oversold trina was and these so called is a seesaw mechanics and the simplest.
Wei Liu-Nanjing University of Science and Technology: series, a new msl modal Okay, so now we say section, you can we're spending the time, so you turn on massive by adding a wind tunnel so called the tagline says so.
Wei Liu-Nanjing University of Science and Technology: Now we can see how to help it has it hard rules that we are true and so some more terrible way is to find the right hand channel.
Wei Liu-Nanjing University of Science and Technology: And most powerful most of promising environment, it is at collider with the lcc and SLC with the production process.
Wei Liu-Nanjing University of Science and Technology: channels, including as channel production like violence detailed stumbles on aws it symbolism or virus on TV channel buys a PDF process process and we are going to shows that all those is overseas process it's not going to the probe the season, we can answer.
Wei Liu-Nanjing University of Science and Technology: That is because of all this process, the Kenyan owns it attic start mixing and we are going to introduce now so like.
Wei Liu-Nanjing University of Science and Technology: Costs so neutrinos has like has mass audiences and the flavor agassi's and the ends a mix between jazz and calling because i'm mixing as an actress from Sarah i'm mixing.
Wei Liu-Nanjing University of Science and Technology: Okay, and if you're downloading some mass mass measures, and you have savings addison so scrolls at an atmosphere and mixing is approximately two is the.
Wei Liu-Nanjing University of Science and Technology: ratio between the sunlight between on mass mass and so having trina was since we knows the line to master only ev and Brian trainer we are looking for us as creators, so we should have muscle gv to this means as P squared is very tiny is going to be smaller than 10 minus 10.
Wei Liu-Nanjing University of Science and Technology: So you can see here is a current salary officer and.
Wei Liu-Nanjing University of Science and Technology: The name is old house they're having trouble searches So you see that this black dotted line I the tab Oh, I see so aeration relation.
Wei Liu-Nanjing University of Science and Technology: and always is the current a flood searches the way, including some proposed one on normal going to pro pro plus the time I see so Sam means that we need to know, for us, or, for that channel to prosper nyc so.
Wei Liu-Nanjing University of Science and Technology: So what we come to realize that it was around tree no will are copying to other page send it can produce a bias against both on case to which was against to be the female Okay, which is a simulation while seamless model.
Wei Liu-Nanjing University of Science and Technology: And if we wish to as such, you one agent and also making this time I see so mechanics more natural, because now, some are one on the train was is going to be produced by a spontaneous Mitchell breaking all this one gauge so like us standby eggs okay.
Wei Liu-Nanjing University of Science and Technology: and
Wei Liu-Nanjing University of Science and Technology: That is cancelled so grateful to have researched possibly answer colliders so we see here it.
Wei Liu-Nanjing University of Science and Technology: Is as a promise and here is a copy so as our see a single is a very powerful to purpose, like some TVs a quiet so for some trees, the plants, the current mixing all the companies tend to want to use a very small.
Wei Liu-Nanjing University of Science and Technology: But was heavily else he has a machine, we have a comma TV Christianity and we are very promising to pro have promises as a plan like with the muscle more than fit.
Wei Liu-Nanjing University of Science and Technology: OK so Indeed it shows a cross session this particular So you see that for like five TVs a prior to access issues is going to.
Wei Liu-Nanjing University of Science and Technology: produce a higher time more sensitive than the lc and even with a very conservative benchmark also cup fish good copy and guess you Helen what vegetables say prime.
Wei Liu-Nanjing University of Science and Technology: So as a product needs to came to appeal centrino and ranching over to care to give us some and what you will find that says.
Wei Liu-Nanjing University of Science and Technology: Okay, and since the brush Rachel was a perfect way to the ranch in is where is pretty large, so we are still going to.
Wei Liu-Nanjing University of Science and Technology: find at least hundreds or having trina frost actual happy as a prime okay well, since we are talking about the production always having to train on let's talk about some signatures okay.
Wei Liu-Nanjing University of Science and Technology: So yes, this so today we are talking about how P Okay, so we find that having a triangle and indeed our P okay it's because our internal a always the case of ISIS a three by the key okay so so you need to decay by us on pitch bows or skaters.
Wei Liu-Nanjing University of Science and Technology: And the candidate heiser said for electronic as a seminar atomic.
Wei Liu-Nanjing University of Science and Technology: And we are going to shows that.
Wei Liu-Nanjing University of Science and Technology: Do to the system mechanics you have this very small tiny.
Wei Liu-Nanjing University of Science and Technology: At this round mixing Okay, and because of this mixing.
Wei Liu-Nanjing University of Science and Technology: And you will see as as detailed as old having the treatment is going to be like meters and within this GB a scale.
Wei Liu-Nanjing University of Science and Technology: I here are all I need to introduce about this nutritional this Cecil then, because we know that can.
Wei Liu-Nanjing University of Science and Technology: mean those efforts there are, and this one neutrino Christmas between 1.4 y UV and it was really sad because we knows as soon as the habits.
Wei Liu-Nanjing University of Science and Technology: neutrino is going to be larger Center support and one up because we have this animal spherical.
Wei Liu-Nanjing University of Science and Technology: trivial matter difference and also the emotional needs to be more than 1.3 because the planet collaboration for the Ascension well from see me see me.
Wei Liu-Nanjing University of Science and Technology: Conservation okay so so basically so it will will point out that it's a B squared is going to be.
Wei Liu-Nanjing University of Science and Technology: Below 1010 okay so every single rose is always it's also fun, because you can you can have a neutrino, which is a lot lighter is and how did you train them.
Wei Liu-Nanjing University of Science and Technology: So they're all good Thomas has some neutrino headwear large the cadence so if so having trina has my middle detailed as we need to see it differently, because normally.
Wei Liu-Nanjing University of Science and Technology: I seen craters we search particles inside so versatile locate the now because his job he indicates at a microscopic this episode of France, the IP, so we are actually going to the text inside Sir God Chakra system or camera system holding events, the mail system.
Wei Liu-Nanjing University of Science and Technology: Okay, and this console having trouble, how are very unique because some is he came forward a Habeas a prime okay.
Wei Liu-Nanjing University of Science and Technology: And, as it passes, he is very powerful so is chemically medical distribution is very different, compared to the our see we see is that to.
Wei Liu-Nanjing University of Science and Technology: versus having trina it's going to have a very large team that means they are larger percentage, so if they are light send.
Wei Liu-Nanjing University of Science and Technology: its final stages me anytime you want young energetic is going to be recording it, so we need some special treatment so so i'm referring to is a paper had her Rosary an actual which is just publishing the archive for the detail analyzes okay.
Wei Liu-Nanjing University of Science and Technology: So also we held down.
Wei Liu-Nanjing University of Science and Technology: The searches or how neutrinos.
Wei Liu-Nanjing University of Science and Technology: As ah ah, so we have dumped two different process, we are not only dancer be myself channel, but also the central channel.
Wei Liu-Nanjing University of Science and Technology: So you know our channel means that so having trouble are produced by it kills a prime sentimental one incentive is productive as a double bottom.
Wei Liu-Nanjing University of Science and Technology: Okay, and here we also show in Santa Clara some curve has labeled TV, this means ncr only particle searches and the cursor control results on means they are promises.
Wei Liu-Nanjing University of Science and Technology: To with CESAR to also LP search how data sensitivity comparing two is a problem, because a pro warehouse where large animal that rocked.
Wei Liu-Nanjing University of Science and Technology: And all the channels are gathers and this animal the Channel because they don't suffer from this.
Wei Liu-Nanjing University of Science and Technology: The inverse proportion of these to be square OK, and then comparing awesome we can pull the large perimeters space of.
Wei Liu-Nanjing University of Science and Technology: Having triangle and the world we find out that okay this LP search, you can pro very large previous space awesome title, I see so so here in a conference of time I see so band and even below it and the event for this problem search we didn't cover metals and, if so, having trouble.
Wei Liu-Nanjing University of Science and Technology: Having all the songs are going to be prompt OK, so our conclusion section, you can test the Cecil as FCC prize package portal okay.
Wei Liu-Nanjing University of Science and Technology: So this figure is very similar just finances is new jj so semi automatic so because you have multiple jets so the price ratio is larger and you get to that her cross section and appropriately lower mixing Okay, everything is very similar.
Wei Liu-Nanjing University of Science and Technology: And I also have one answer so having trouble cannot be to to light up our to realize you're going to kill us and to jess and you're new to.
Wei Liu-Nanjing University of Science and Technology: searches fires Muslim the case and it's going to be performed at the ship Okay, so now we come out solution.
Wei Liu-Nanjing University of Science and Technology: So.
Wei Liu-Nanjing University of Science and Technology: Ralph neutrino Phillip is very interesting, I think the most important, why is that we don't know the regional channel mass.
Wei Liu-Nanjing University of Science and Technology: So I think tab yc so is one seamless and solution and we want to will test them.
Wei Liu-Nanjing University of Science and Technology: And hydrants because Burton.
Wei Liu-Nanjing University of Science and Technology: But if it's a brand tree our producer buyers don't balsam said cannot read property time I see so so we come, so we need some additional engage.
Wei Liu-Nanjing University of Science and Technology: And we rescheduled can additional poison Pfizer additional cash model, and we are short after this and promotional posts around channel.
Wei Liu-Nanjing University of Science and Technology: And if we serve some fires out LP China signature sound, we are going to the task at hand was Cecil as the FCC ashish so as soon as he said, no my talk and then many sex.
Albert De Roeck: Okay, well, thank you very much for this is the contribution and take a few questions, a quick one effect on your slide 10 did I understand that this blue region within the rectangle is everything you take in there.
Albert De Roeck: Yes, for for cross section so so use you I mean that's a displaced.
Albert De Roeck: produce the neutrino but that the case and and you will see the New York acceptance or mean you will take it as your acceptance right now.
Wei Liu-Nanjing University of Science and Technology: Yes, so I see so i'm just reflect and see that said.
Wei Liu-Nanjing University of Science and Technology: All the new trail.
Wei Liu-Nanjing University of Science and Technology: decaying sizes for you.
yeah.
Albert De Roeck: yeah.
Albert De Roeck: Okay, because it's not quite optimally instrumented to to do that, but at least find this gives you the maximum type of of the case, you can see, and that you.
Albert De Roeck: use for your.
Albert De Roeck: Good okay good just I understand thank.
Federico Leo Redi: You, thank you very much, and this is very interesting, can you go to slide 20 Oh, please.
Wei Liu-Nanjing University of Science and Technology: yeah.
Federico Leo Redi: So when you look at the region between when above the child interaction.
Federico Leo Redi: So when they came for ship is.
Federico Leo Redi: Below six seven of you, and you can see, the different production modes to study hmm productions in FCC.
Federico Leo Redi: For example, come from bs or payables come from keys.
Federico Leo Redi: And we will try to explore noroviruses.
Wei Liu-Nanjing University of Science and Technology: I think for pound for a dancer as an llc so yeah so having trained or reading this mass where's he going to dominate and produce spice based on the case and.
Wei Liu-Nanjing University of Science and Technology: I haven't seen anyone do it actually helps you see a church.
Wei Liu-Nanjing University of Science and Technology: That was going to be very different.
Federico Leo Redi: i'm not sure I mean it requires a different studies is clear, but it should be possible to say okay yeah.
Albert De Roeck: Right thanks, is there a quick final question.
Federico Leo Redi: it's already making minutes, so we can.
Albert De Roeck: yeah I know I know.
Albert De Roeck: Just that the containers don't you know monopolize all sessions.
Albert De Roeck: But it's not in this case thanks again and.
Albert De Roeck: And I mean now go to Guillermo Guillermo can be nice, which I think is around and this talk is there.
Hello.
Albert De Roeck: hi there, so if you can share your screen.
Also.
Guillermo Gambini: Yes, can you see it now.
Albert De Roeck: Okay, we see it, we hear you and you're gonna tell us about neutral lentils interacting with single scallops take it away.
Guillermo Gambini: alright.
Albert De Roeck: First, I want to thank the organizers.
Guillermo Gambini: For the invitation, and I would like to thank everyone for.
Coming.
Guillermo Gambini: Yes, this.
Guillermo Gambini: Thought will begin with discredit him national level in the world, nobody, but let me talk about me a lot and then how we.
Guillermo Gambini: think that we use to to reproduce the limits from male female in terms of experiments.
Guillermo Gambini: And then, with the new what happens when we are a lightsaber skaters that the couple's to to the child and also mix with his alright.
Guillermo Gambini: So yeah so so we're we're done between those are massive and our sense of what the the end of the last millennium right.
Guillermo Gambini: But the question is how do we know that they have mass, and this is the short answer is digital solutions right, it was a simple explanation to the environment, you no problem.
Guillermo Gambini: And that requires us to be massive right and also they have different muscles.
Guillermo Gambini: And how they can master nodes if the higgs mechanism is it extra dimension is it something else.
Guillermo Gambini: I don't know but.
Guillermo Gambini: I think nobody knows, but there are many When will they be the proposals that we tested in the laboratory right so here i'm going to talk to you about something that isn't.
Guillermo Gambini: Very quickly, you know we've we've sample which is offer a new standard model single information that makes us with the electric material.
Guillermo Gambini: exclusively with the regulatory but this case we have this must matrix for for this this editor to know and news in agent of basis right, you would allow us to compute.
Guillermo Gambini: The muscle.
Guillermo Gambini: Mass equals zero anymore, we have to do this one, there is this more mass and one this heaviness and.
Guillermo Gambini: And, but we want to know what it will be, who has this mass right in the right state is it's mostly the neutrino right and small fraction of the new symbol.
Guillermo Gambini: Right and then, but then the most massive state defender one is mostly the new the new state right.
Guillermo Gambini: And what characterizes the new fiscal year and that.
Guillermo Gambini: Is this ratio between these two are no parameters, like the.
Guillermo Gambini: So, since they tell us what the physics, is there, we will be looking for them, for a long time, and we can just simply calling.
Guillermo Gambini: mixing able important for them and asparagus.
Guillermo Gambini: go, so this is going to do understand don't experiment at all yeah still experimental this because there are victorious, including with personal stuff that I.
Guillermo Gambini: know another expert right, so I just want to say that we think of electric posters colliding right, then it would produce much particles.
Guillermo Gambini: Like did they come to the right energy they can produce these symbols a they can decay right into let up like electrons murals now in headphones in between us right and and I respect this new physics to manifest you know, in the mixing with with uh with like your dreams.
Guillermo Gambini: And and produce and produce the skill development and it's going to let them can actually the K for week interactions right like this nutrient rich or church not church currents and produce person left on the trailer supports only patronize and know.
Guillermo Gambini: Okay, so we can use this this this this experiment to put constraints on the on the mixing of the html of videos that are mostly with furman with the activities right.
Guillermo Gambini: And that's what what's showing this figure one on the right, which is the mix, as well as a functional of the mass right everything there is about this this line is below 99% confidence level by the progression and what we.
Guillermo Gambini: Did in this work was to add the same for me no it's a ton of models similar.
Guillermo Gambini: scale so like the others, so we have this simple scatter and the simplest form and both of them interacting.
Guillermo Gambini: With would change the limits on.
Guillermo Gambini: On this mixing angle, because, first of all, the singlet can mix if you can, if you can mix with the higgs boson it can be very dedicated to personal performance.
Guillermo Gambini: There are there is, for example, an experiment what it looks for right, and so this thing that could be faking it could be mimicking The case of the of the journal of the week case right, so we want, we wonder what happens to this.
Guillermo Gambini: Very briefly, if you describe how we, the method that we use to regulate the slave to the first way to be coffee and that we can reproduce these limits.
Guillermo Gambini: And we're but by and, with it, by fighting that the number of events by number of events, this is the number of articles, the weather with paperwork probability.
Guillermo Gambini: Three properties is actually one of of producing each email and then have the agenda digging into what is look for for productivity and profitability is pretty well experiment, but I also wanted to know.
Guillermo Gambini: If we can reconstruct this event right.
Guillermo Gambini: experiment where where the detector is far for the dark light is showing this figure this Sunday, this is the last formula, the third priority if we have a Delphi.
Guillermo Gambini: Little poster positions inside the vector right, and then it will be zero and we can define.
Guillermo Gambini: The scope change themselves what we did was to compute the fraction will do is actually agreed We may agree or what ankle good in every in every point is is very disappointing.
Guillermo Gambini: And then we converted to the we compare the results to the Polish result of the Corporation.
Guillermo Gambini: So we just were first blood contours of these are the freshman prevent but for 10 to the minus five minus ever himself okay this close but not good enough, and then we found that for 10 to the minus six, approximately we get this red line.
Guillermo Gambini: There would fix you know, but still have a problem in the lesson for later, two years later he knows and then for one or two one or 200 centimeters we get this result and blue.
Guillermo Gambini: The one we use for now, as the as the limits, from which case for from nothing.
Guillermo Gambini: And, with the same for for very job with at some discrepancies with with with will result in talk about later if someone's interested but.
Guillermo Gambini: Here I want to raise question we have two questions here too, so so when we add the single day, because things are much change this one when.
Guillermo Gambini: We indicate which are usually the case you know for the original or the new channel that the door is stored in case you know the singlet and treatment, the trick when the when we went to fight these.
Guillermo Gambini: Questions over here and now Okay, regardless of who wins what's going to happen that I want to be more educated inside the doctor or what was what was gonna happen it's gonna happen there.
Guillermo Gambini: With original don't fight formula look up here we can get the limits, though the the chatroom for blue light a light look for for.
Guillermo Gambini: For the experiment and when we had to submit this change the format change a little bit you know what's in the production of the lesson, but end of the day, and that the length of the length of the Internet with change also there will be increased by her with each other.
Guillermo Gambini: alright.
Guillermo Gambini: So this is the most interesting part which is a bar will show you the results.
Guillermo Gambini: In blue we have.
Guillermo Gambini: The limit with beer with with interactions and when we add a scene with the fest this particular mixing with with a fixed most on demand service by mixing.
Guillermo Gambini: there's the law by by its purpose of our and couples today chanel's with this treatment for strength that i'm showing you right.
Guillermo Gambini: It will change the limit opens that but I went to space, you know when they simply schematically allowed to reproduce like, in this case it's a hgtv simple that can you know start here.
Guillermo Gambini: And then the brother space opens but it goes again no approaches the.
Guillermo Gambini: door, you know limit from from with the case because the noise, the production is suppressed yeah because.
Guillermo Gambini: it's all of this is for when you're under the tree knows it's in the case of your mixes right, well, we only good for electron here or TAO this case.
Guillermo Gambini: Let limits are independent of each other favors right so we've done that, for many other configurations for different masters of the simplest form with debbie be to eight around a gv.
Guillermo Gambini: Now, and for a small mixes with with explosive and you know, sometimes we have we opened the problem space a lot sometimes not so much as sometimes we had a virtually closer.
Guillermo Gambini: But yeah let's let's do that with results that are very similar to the.
Guillermo Gambini: result of difficult to see you know we'll take it up.
Guillermo Gambini: With a safer well right here i'm showing you for mixes with electron and for noon.
Guillermo Gambini: And the interesting thing here is that for well, we always opened up our space.
Guillermo Gambini: Because you know, we have the singer that if it makes the The case of of the original right.
Guillermo Gambini: Then we can change the limits can open or closed if i'm a space where you just taste the simple to navigate into what well, it looks for which are.
Guillermo Gambini: we're a violence and laptops together right, so they tend to go up to the top so that's why it's like they're likely, the case of the same and the parameter space opens up the space.
Guillermo Gambini: A for Congress Okay, and for turn.
Guillermo Gambini: we've had something similar to what to what happened to just fight sometimes space open and sometimes it's closer to know.
Guillermo Gambini: Sometimes we got with the original because the similar now can decay and were you supposed to be anything, no.
Guillermo Gambini: And that would actually give a signal that we were we interpret us the company of the.
Guillermo Gambini: Of the original with with the new tricks.
Guillermo Gambini: So.
Guillermo Gambini: So okay our recruiter completions, and these are that just we can open the brothers face in many cases well we're late to the scanner or recommended, you know we can mix it in the cup the role of the other mixing with the higgs.
Guillermo Gambini: We let this work, but so.
Guillermo Gambini: And also, this method is you know saves us a lot of time if we didn't have to do any expensive and what he got simulations that we don't know the lower loser.
Guillermo Gambini: that's good and also.
Guillermo Gambini: If you can be used for other experiments and only the weather, that was shown here, but for the thing that group may be interested.
Guillermo Gambini: Yes, so I versatile you retry and I was more than that, thank you.
Albert De Roeck: All right, thank you.
Albert De Roeck: Right interesting contribution, but i'm still sort of model it in my mind exactly what the message is just for for for right help, so the the limits you calculate is that assuming you don't see any experimental signature of the singlet.
Guillermo Gambini: Yes, exactly that's what this person doesn't write a.
Guillermo Gambini: Number of the rest of their.
Guillermo Gambini: Life yes.
Albert De Roeck: that's events you lose because of of it they're going to a single day you don't observe that.
Guillermo Gambini: Exactly the same.
Guillermo Gambini: But if it's.
Albert De Roeck: You know.
Albert De Roeck: Firstly, you could.
Albert De Roeck: You could try to try to detect the singlet.
Guillermo Gambini: Exactly yes okay.
Albert De Roeck: But that's not what you what what you discuss here just how our face face gets reduced by the calls that you have this extra singlet in the in the in the production.
Guillermo Gambini: Okay.
Albert De Roeck: yeah okay thanks.
Albert De Roeck: Joanne.
Giovanna Cottin: hi yes thanks Guillermo just a quick question this mixing is the meeting with the simulate, this is why it's in the independent more than the flavor, as you said.
Guillermo Gambini: Oh yeah.
Guillermo Gambini: Just the mixing.
Guillermo Gambini: mixing.
Guillermo Gambini: For a SEC here just to have missus exclusively with electrons trainers exclusively with military yes.
Giovanna Cottin: But in your previous blood, you have the constrain upper limits on the mixing with the light skater.
Giovanna Cottin: This one yeah.
Guillermo Gambini: Oh yeah oh sorry yeah.
Giovanna Cottin: Okay yeah yeah.
Giovanna Cottin: yeah yeah Okay, yes, thanks.
Albert De Roeck: Good clarification some any further questions for them.
Federico Leo Redi: Yes, thank you very much, so assuming one wants to.
Federico Leo Redi: Let me understand why did you pick the alphabet and charm specifically.
Guillermo Gambini: Oh yes, we were interested in us in the masterminds from about.
Federico Leo Redi: below the.
Guillermo Gambini: Threshold yeah below 10 GB wallace, and so we started looking for other leaders from atlas and cms.
Guillermo Gambini: Also competitive.
Federico Leo Redi: We don't they're not competitive.
Federico Leo Redi: There, or the leading.
yeah yeah.
Guillermo Gambini: yeah.
Federico Leo Redi: perform the same exercise, also with the.
Federico Leo Redi: With those limits.
Guillermo Gambini: I really good yeah I.
Guillermo Gambini: know but yeah.
Federico Leo Redi: Of course, the production moans very.
Federico Leo Redi: And then you also have different production moans from from.
Albert De Roeck: They made maybe you want to discuss on matter most because I think you do have to move up.
Federico Leo Redi: Yes, okay.
Guillermo Gambini: Thank you.
Guillermo Gambini: Alright well thanks very.
Albert De Roeck: Much again.
Guillermo Gambini: Thank you.
Albert De Roeck: We not go to the next week and I think.
Albert De Roeck: It takes oh.
Krzysztof Mękała: Yes, can you hear me, and can you.
Krzysztof Mękała: Yes, so i'm trying to share my slides.
Albert De Roeck: That works fine.
Krzysztof Mękała: Yes, maybe just try to make it as a presentation.
Albert De Roeck: And even bigger very good.
Krzysztof Mękała: Okay, can I start.
Albert De Roeck: yep.
Krzysztof Mękała: Go ahead, thank you very much okay.
Krzysztof Mękała: Great, thank you for the invitation I want to talk about.
Krzysztof Mękała: Having a trainers that future a plus or minus colliders and this work was done in collaboration with you're going to writer from Desi and Alex in the future let's get from university of horse oh.
Krzysztof Mękała: And the Paper describing the whole analysis is available on our pipe, let me start the presentation, with a short introduction to the topic, as we know, there are some problems in the standard model.
Krzysztof Mękała: Basically, connected with with some cosmological observations I mean these observations are the most convincing ones that there is something beyond the standard model.
Krzysztof Mękała: In some theories, we have these problems neutrinos are connected.
Krzysztof Mękała: Then we can try to explain such problems as dark matter density very honest demetri and so on, by introducing, for example, new species of neutrinos.
Krzysztof Mękała: In many models and this neutrinos are very happy, they can be light heavy right handed and so on in many of these scenarios.
Krzysztof Mękała: This new trainers are heavy and over in many of these extensions of the standard model, then you train us or weekly coupled to the standard model, and then they are luckily.
Krzysztof Mękała: However, in my presentation, I want to focus on from the case of the heavy trial leptons So if you want to get to know more about.
Krzysztof Mękała: Heavy long grief neutrinos you have to go to other presentations but still I think that my presentation can be interesting for the audience, even if I if I I focus on on on the shortlist neutrinos.
Krzysztof Mękała: To the question is how to introduce the heavy neutrinos this model.
Krzysztof Mękała: Well, the easiest way is to add some terms to the standard model lagrangian first one can add the term corresponding to the heavy neutrino propagator and then some terms, corresponding to new interactions.
Krzysztof Mękała: In our case, we have three new vertices we have interactions with w we've said and higgs boson and this kind of scenario is a similar scenario we don't have any additional gauge bosoms we just have certain model bones and extra new trainers, of course, one has to implement.
Krzysztof Mękała: Certain model to to do any analysis and then we use the heavy and model it's a new model implemented within the finals.
Krzysztof Mękała: And the kind of an effective extension of the standard model and the toes of this model was done, because the model was widely analyzed for such as a pattern colliders you can.
Krzysztof Mękała: find many different papers on this topic in the model, there are free, new having a train us, they can be both my Iran or direct particles and they are the note at us and one and two and then three.
Krzysztof Mękała: In the model, there are 12 different free parameters, first we have free masters of this free new neutrinos and this mass is can be said in the range from hundreds of gv up to a few thousands of D and.
Krzysztof Mękała: ender also nine mixing parameters which are just elements of.
Krzysztof Mękała: Three by three mixing metrics between the standard model leptons and this heavy nutrients.
Krzysztof Mękała: And, of course, the question is where we can sell it for such neutrinos.
Krzysztof Mękała: Because if we want to search for these particles, if we want to observe from the case, so the case of such particles into some standard model particles.
Krzysztof Mękała: Then, an important thing to do is to reduce background and possible background contributions to our analysis one way to do so is to use future.
Krzysztof Mękała: A plus or minus colliders as as the the ones listed here so currently there are four different proposals of an a plus C minus machine.
Krzysztof Mękała: FCC and CPC which are leaner sorry supercolliders and irc and click which are linger colliders and in this presentation, I want to focus on irc and click because leaner colliders offer.
Krzysztof Mękała: Higher energies and if we want to search for really heavy particles, then we just need high energies to do to be able to produce this particles.
Krzysztof Mękała: Let me say a few words about each of these proposals, so first i'll see it's a collider to be built in Japan, and it would.
Krzysztof Mękała: Use superconducting exhilarating cavities to accelerate electrodes and positrons.
Krzysztof Mękała: length of this product is assumed to be 31 kilometers and he do the offer energy starting from 250 TV up to 500 dv also there are some considerations concerning the zippo and also there is a possible upgrade up to one TV.
Krzysztof Mękała: An excellent feature of this machine is that both beams is equal be polarized at the level of 80% for electrons and 30% for positions tomatina colliders another preposition to.
Krzysztof Mękała: be built at CERN and it would the US and other accelerating scheme and novel scheme of of using two different beams first drive beams.
Krzysztof Mękała: Providing the radio frequency power to accelerate main beams and then it would be able to achieve enter this APP to free TV.
Krzysztof Mękała: But they're free different enter the status of some assumed for this proposal, starting from 300 at gv 1.5 TV up to up to free TV and click only electron beam would be polarized at the level of 80%.
Krzysztof Mękała: Okay, in our analysis we focus on the single having a trainer production and to search for this process.
Krzysztof Mękała: We can use many different ways, there are above direct ways when we searched for some trump signatures for example kiki and you continue in your new and also some indirect methods like electroweak precision observable his branding gracious and also if that neutrinos or lundqvist.
Krzysztof Mękała: The space versus are possible as well.
Krzysztof Mękała: In in this case we probe the signature of poop works and.
Krzysztof Mękała: works leptin and and neutrino because it allows through direct reconstruction of the having your trina if we are able to measure cadets and the left, and then we can say something about mass of the of the heavy neutrino.
Krzysztof Mękała: In our setup we considered both directions myron and neutrinos but in this presentation, I want to focus on on the directors.
Krzysztof Mękała: And one masters were set to from 200 dv up to 3.2 TV and masters of end to end and free particulars were set to 10 TV.
Krzysztof Mękała: All the companies have an one were set to the same value and the value of point or free.
Krzysztof Mękała: was used for the generation of reference signal samples, but in general, this parameter was a free parameter of our analysis.
Krzysztof Mękała: And Oh, the end to end then free cufflinks were set to zero, so, in other words, we have only one having a tree nine the game.
Krzysztof Mękała: We considered three different collider scenarios, but I want to focus on irc 500 dv with an integrator luminosity a fine point 16 years after bonds and and polarization of minus 80% for electronics and plus 40% for positions.
Krzysztof Mękała: Here you can see a cross section for for for for our signal process for different collector setups.
Krzysztof Mękała: For left right polarization including spectra important thing to observe here is that the Cross section is almost uniform up to the energy threshold is of the order of 10% Oban for for each provider and then in decreases very fast up below tend to the second and so on.
Krzysztof Mękała: Of course it is not a kind of background tree analysis, because in the standard model we have many processes which are.
Krzysztof Mękała: which are in fact background for these kinds of searches and also the same process can be mitigated with flight neutrinos right, so we have exactly the same diagrams.
Krzysztof Mękała: When we replace the having a trina with a light one and then, and then we have an example of background process, but of course there are also many different processes which can can can contribute to this analysis.
Krzysztof Mękała: Now I want to present to you our analysis procedure so first we generate a physical events with wizard basically the word two groups.
Krzysztof Mękała: Of the event so first we generated our signal again he plus the man who is going to a light having a juniper and then having it really came into two quirks and a laptop and it's our signal and the background, so all the processes without.
Krzysztof Mękała: And propagates without having a trainer and in the analysis, we also included a gamma gamma gamma bedroom channels.
Krzysztof Mękała: Then we simulated the director response with Dell first it's the first simulation framework which allows two parameters our detector acceptance and in the next steps we pre select.
Krzysztof Mękała: We pre selected even matching that required signal topology in this case, we wanted to have exactly one heavy neutrino so do get the signature.
Krzysztof Mękała: We searched for the events with two dates and one laptop and that's all and then we use machine learning can CLS to get our final results.
Krzysztof Mękała: So please look here at this flow of the key que El invariant mass after the press election.
Krzysztof Mękała: State, so you can observe three different careers, for he background and gamma gamma and de gamma background and also for our signal is the kind of reference scenario with most of the having a train of 300 dv and you can observe very visible peek.
Krzysztof Mękała: At at this free hundred Davey which corresponds to the mass of the having a trainer, of course, the signal is below the background so it's not perfect, but still, you can see that this this variable is really powerful in in discriminating between a background and signal samples.
Krzysztof Mękała: Then, as I said, we use the the machine learning in this case, it was the boosted decision trees algorithm with eight input variables and in this blood, you can observe distribution of the ability response for background and signal, it was done for for again for the same scenario with.
Krzysztof Mękała: With having neutrino with mass of the of free hundred dv and to me on in the final state, because at this level, we treated separately.
Krzysztof Mękała: electrons and nuance in the final state and, as you can observe this distributions are not separated, but still, you can see that that there is a kind of separation between these two distributions.
Krzysztof Mękała: Then we we implemented the CLS using the bdd response distribution.
Krzysztof Mękała: To build a model within your stats and then we were able to combine tunnels and also implement normalization uncertainties here, you can see, steel results for electrons and me on separately.
Krzysztof Mękała: This are limits on the cross section for the for our signal process as a function of mass of the heavy neutrino.
Krzysztof Mękała: you're going to see the results for from your answer slightly better because this or exclusion limits, so we want to have them as low as possible So yes, so results from your answer are slightly better but, but in any case, the results are of the order of open one or one from the box.
Krzysztof Mękała: Then we translate it our results in into a plot, which is a bit more convincing I believe here, you can see limits on the V squirt it's our mixing parameter compare like for results from our analysis and for different.
Krzysztof Mękała: from different analysis so first, you can see results right at 500 gv is the one TV and click free TV compared to results coming from the cms this are currently limits coming from the real experiments and this are predicted.
Krzysztof Mękała: results for HALO me la see high energy latency and FCC a tight, you can see that results for for the electron positron colliders or by orders of magnitude.
Krzysztof Mękała: more stringent than those obtained at at hundred machines, one important thing here is that.
Krzysztof Mękała: In this analysis with this 300 machines that there was a kind of different assumption, because they exclude the towers from the analysis, so they does get.
Krzysztof Mękała: slightly better results because of this fact in our analysis, we still have thousand if we exclude thousand analysis, we will have even more stringent results than those presented here.
Krzysztof Mękała: And the last question in my presentation is if the neutrinos a really strong for you.
Krzysztof Mękała: So, in our case for the lowest masses considered in this study again it was at the order of hundreds of dv the limits.
Krzysztof Mękała: obtained in this analysis correspond to width of the heavy neutrino at the level of a few a killer electron volts and then see TAO is below one nanometre so in any case, we are not able to observe.
Krzysztof Mękała: Any displays vertices, for example, because then you train us from the experimental point of view, a really sharply, of course, one important thing here is that.
Krzysztof Mękała: In principle, we can assert for for a long week neutrinos in in this kind of model, but then the masses of such a political should be below or a dearth of mass of the of the dub it brings me to my conclusions.
Krzysztof Mękała: In I hope I convinced you that that future a blessing Magnus colliders we would be able to to search for having a train us in a direct way and then neutrinos could be observed, almost up to almost up to the kinematic limit and the results are.
Krzysztof Mękała: much stronger than those that tell it see or if any other hadn't machines and our analysis was already accepted for the day happens, it should be published very, very soon, thank you very much for your attention.
Albert De Roeck: Thank you.
Federico Leo Redi: Okay, thank you very much, that was a 15 minutes shy.
Federico Leo Redi: So let's see if there are any questions.
Federico Leo Redi: If not, I will start by asking you a question related to.
Federico Leo Redi: The block you Sean slide 16 so of course Okay, this is the money blocks Ascension.
Federico Leo Redi: Now.
Federico Leo Redi: Like, how do you like, how did you take these lines for the elysee like, for example, I I heard you mentioned the fact about the TAO.
Federico Leo Redi: Could you elaborate on that and and.
Federico Leo Redi: Yes, please is the cms line.
Federico Leo Redi: Yes, yeah.
Krzysztof Mękała: Okay cms line comes from the data so it's it's a kind of.
Federico Leo Redi: An extraction you did yeah you know it's not our extraction.
Krzysztof Mękała: it's does the paper published by the cms.
Federico Leo Redi: But that's the solid line.
Krzysztof Mękała: This one these.
Federico Leo Redi: Are the entire line okay.
Krzysztof Mękała: Yes, this one, and this reliance came in from this paper.
Krzysztof Mękała: So.
Krzysztof Mękała: It was the same analysis, the same type of analysis, but for hadron collider so.
Krzysztof Mękała: The results are just extracted from this analysis and it was done for this basically the same model but we've this assumption that they don't have taught in their analysis, because in a place, they have only two non zero cufflinks.
Krzysztof Mękała: So they have on the electrons and he wants.
Krzysztof Mękała: In our case, we have.
Federico Leo Redi: All that.
Krzysztof Mękała: To the free electrons and, of course, because towels can escape the detector that's.
Krzysztof Mękała: My device, then our results are slightly worse.
Federico Leo Redi: But then, but then the natural question is what would your life look like okay.
Federico Leo Redi: yeah better by an order of magnitude or.
Krzysztof Mękała: not really we we try to do it for for some points, and it was like a factor of a few but it's not very easy to like extrapolate our results, because then you just have to rerun the whole analysis.
Krzysztof Mękała: Because.
Krzysztof Mękała: it's slightly different, for example, for lower masters, when you have.
Federico Leo Redi: Children, you have to.
Federico Leo Redi: Do the whole thing yeah.
Krzysztof Mękała: stands for very high masters like to.
Federico Leo Redi: OK OK OK, but then this block is, if you want dangerous for you, because.
Krzysztof Mękała: It could be better it's like i'm.
Federico Leo Redi: pessimistic assumption section.
Federico Leo Redi: Okay, thank you.
Federico Leo Redi: I also see that she has a question we have time for that yes.
Xie, Keping: We just do honors this, since we are in the cockpit of the long new particles here they're doing a lot about need to be, it is about this.
Xie, Keping: or can we improve your your your sensitivity with this new product signature that displays fantastic does your your this.
Xie, Keping: week's angle going to tend to monitor seven.
Krzysztof Mękała: Yes, so, in principle, you could go to long articles, but then your cufflink would be so low level that probably you would produce like a few.
Krzysztof Mękała: Having a trainers so observing such a particular would be very challenging so I not really sure if if really we can get better results from the from the.
Krzysztof Mękała: For example, displays the vertices analysis for for for very low couplings and for very high masses, because you just have to allow particles sorry to few articles to observe something.
Xie, Keping: Okay.
Federico Leo Redi: Should we.
Federico Leo Redi: Sorry, we have to cover here, because the time is already quite late on the schedule, we can follow up on matter most anyway, anyway, she now is your turn, thank you very much.
Federico Leo Redi: For your for your total cost of okay so keeping you can see, you can you show your slides, please.
Xie, Keping: I will say.
Federico Leo Redi: One second it's loading, for me, yes, can you try you try to change them or to go to the next, oh yes that's perfect okay so you're talking about Internet searches at the collider Okay, thank you very much, please go ahead.
Xie, Keping: sangha sangha yoga either for this limitation and.
Xie, Keping: Better okay or fast to play in our without here, and if you are trees down with a few colleagues impede like brown but hey on and on and also so R rated hard hard hard costs, you know enough equity in HR I India, so we have submitted or throw mass white papers.
Xie, Keping: few months, two months ago, roughly under their work, the wheel papers dream some more official work they come very soon and.
Xie, Keping: Hopefully this month, so just give us all very simple introduction and motivation, since he is a he left from i'm kreider is a pool of the door and they were definitely will be built.
Xie, Keping: In blue Kevin and national lab and since this heinie Costa kreider are aren't we can we need to take advantage of this kreider to explore as much as we can, of course, the human.
Xie, Keping: yeah save money features I just need some of them like polarized electron being a new new crown P, including most on a proton beam.
Xie, Keping: Under the can also extend to heavy iron, and that is SLIM indicators so we can have the you also from this to determine or eBay heavy a I am on like a union or need.
Xie, Keping: Some time as a nurse it's not very high up to two optimistically to 140 G H, a part of the biggest advantage for this kreider is high luminosity compared to the existing.
Xie, Keping: Then you'll have to come the DS machine nika here, are you can reaches the factor of 10 of it up to 31,000 times come here to exist in numerous or dates.
Xie, Keping: So, of course, the door for years is money for God as of Tuesday machine to applaud their problems, praying, and all this park room container or products or even you have an eye on.
Xie, Keping: However, we should also take advantage of this machine to think about other physics right he left home with.
Xie, Keping: Precision physics, or even bsm so I give a nice Lisa or even a very big or walk through mass white papers.
Xie, Keping: Here, which is the layout or on Monday for energy there and our standard long have a White Paper, our standard for long study we'll start with one of the case study in this direction, so we take this to have a new top level home as an example to oh.
Xie, Keping: So let's say we call it a bit about us setup although or yeah yeah say which we are take in our inputs.
Xie, Keping: On under the electronic machine and then the ice machine energy with our main indicator come up to 142 waves, so you have to be implementing I listed here.
Xie, Keping: So integrated illuminati I just just so you can be up to 100 immersed in the bar under the detectors the configuration it's like this.
Xie, Keping: course, you have the proton come from one direction, and then you know from from another direction in under the basic setup like the tracking system, the kilometers and also this.
Xie, Keping: compact car richie I just do some basic has come up to 3.5 in the forward direction in so which is.
Xie, Keping: kind of impressive.
Xie, Keping: So, so this is a basic up, we will take that under for our inputs so let's look at our So what we can do with basic this machine, so we do we take this to have a a neutral.
Xie, Keping: neutral after models so I just know right all this this basic lagrangian under the corresponding interaction with the standard model, mostly from this kg he the bottom w and the day.
Xie, Keping: Under the Cross section I need to hear compared to this.
Xie, Keping: normalized two days, two weeks ago, it can reach you to kind of 30 a a peek bar nerd so so when we tom's to consider about this new this new browser here to which is happening come to.
Xie, Keping: 100 immersed in the bar so the events that we consider we missed mix and go to be unit unit, the events can be up to one meetings events.
Xie, Keping: So so that's a significant advantage compared to the listing team in a machine or even released in HARA like that, so when we voted into this.
Xie, Keping: considered about it is weeks ago, so we can you be wanting to produce these habits, a new neutral everything up to order one or 210 event.
Xie, Keping: It can be reaching out to the sensitivity to this mix angle down to 10 minus six that's that's our hope to explore this with this machine.
Xie, Keping: In so so let's see how far we can go let's let's first nice about this to kind of go to scenario to kind of a particular region, why is kind of a high mass.
Xie, Keping: Higher mass with smaller or larger mixed angle in this region, we will all this one is mostly in the US for, for this is a promoted the case archie so I need to view.
Xie, Keping: Signature channel I can the morale type we can have all charging the flip side with a few heavy jets and also, we can also have all these charges williamstown with.
Xie, Keping: Also flavors changes channel as the new channel docs, which is also singing very unique signature from our our have an introduction part of what you don't want to.
Xie, Keping: have a home, so we can we don't have some unique, so we have just a normal thing REACH, and I can tell you that's left on prescription.
Xie, Keping: coverage, you are the possible combinations so so oh for them marana wizard.
Xie, Keping: leave it to the next one, Sam I will put together a three type of jed we have all the bondage to we will solve all the state, so we can reconstruct this the heavy leptons on emerging mass so so, for example, we can take this.
Xie, Keping: The 10 db or having items I know we can for the construct of the heavy left these are there emergent master based on this one, you can say to come down to this to the bed guang.
Xie, Keping: guang early so spread out all about a single dog will be located around the yours you're having left your left arm mass Martin gv this so unique signature data we continue them only to.
Xie, Keping: To isolate or to suppress the Bourbon and I think TAO to also simplify this a bad signal so let's talk to to focus on this this signet chart a first step, so so.
Xie, Keping: This is because this is simply charlie's can give our strongest signal or.
Xie, Keping: Under, we have also perform these are all there for configuration that detail simulation under we have optimized these cards kind of medical to sin to do you order to.
Xie, Keping: magnify the signal as a brick wall I need to offer them and then the car flow taibach here under the biggest Babylon and coming from this misidentification of the uniform on and.
Xie, Keping: Because the large events coming from this just to the DS scattering which it doesn't miss identify one electron with your sleep Sam I with a free faith have faith, for instance, so so reach out to optimize this a business card flow and under them then.
Xie, Keping: Then we found this some math window, this is, I mentioned that the murder master car to come largely have any suppressed this background.
Xie, Keping: I know we take advantage of this one under the currently existing in in most precise to me, he said, the identification of electrons.
Xie, Keping: Are reciting in a way that can be up to a point 1% so So this is the existing can we can take part in the future let's the project some.
Xie, Keping: One one or many the improvement in the future, so we can, given the opener better serve our banner sensitivity and let's say this is the sensitivity of what we can get.
Xie, Keping: So, so you can say this, we got two projects is to have them with to misidentification efficient saves the, why is the existing portal one person, why is the future we.
Xie, Keping: gotta you to assume one order magnitude improvement because he said this sensitivity, based on this this.
Xie, Keping: simulation we can at na GE emerging ma na GE haven't optimized can order of 10s G webs we can reach you can do this mix tango i'm to come to manta Ray sometimes can be a boy can improve all this, besides me give me rapes, we can even reach it and romance for.
Xie, Keping: All those that that's a message if RON a problem with the case archie from course we also consider about other channel like we have mentioned about this, but even found with the.
Xie, Keping: New flavors channel for this one and which is unique thinking which are part of our father, however, we have a significant big one, coming from this how.
Xie, Keping: tk which with with medical playback this we are polluted this this signal so so the will come and without her this channel give us comparable sensitivities him.
Xie, Keping: under other directors, the directors signal, so we have we don't have a unique signature, so we have to form this.
Xie, Keping: London, Paris, without the Plaza signatures one Jerry transmission energy do under we get give some sensitivities, which was really give us the same similar sensitivity committed to the mix angle with.
Xie, Keping: The demonic type so that's the main message from this promoted became hey since we are talking about in this nandi.
Federico Leo Redi: parts are your four minutes to go.
Federico Leo Redi: Okay, thank you.
Xie, Keping: Well we're talking about is an unusual.
Xie, Keping: Sydney Charlie particles you breathe out of our nature for us to take this signature to identify, this is heavy leptons.
Xie, Keping: Under the finance a lot of devils the particles, so we, such as the oneness and emerging markets that have another master to be small under this mix angle to be small region, this is left.
Xie, Keping: Lower corner, this one will correspond exactly to this is the nandi walls particle signature under the idiots we show this.
Xie, Keping: But he can dance, can you can see, up to that the technical side.
Xie, Keping: Under we have a dandy simulation and the US, this second HR we have the penguin we also actually take consideration or Sunday models to have it's like a.
Xie, Keping: marathon because with the signature and can say this is a dms on what been as on the case that's under.
Xie, Keping: Oh no longer part of your signature so for this give you four five TV having everyone can be a, which is to significantly.
Xie, Keping: Inside of your did have our other others which you read fundamental background can be suppressed.
Xie, Keping: So, so we have a little perform this is the vendor selection naca some typical events tracking and we take them in this.
Xie, Keping: Some typical turns the transverse impact factor in packs that are under performing the flow simulation of their detectors size or configuration that is sending hearts.
Xie, Keping: For size under we have get an insulin sensitivity it is we use this wrongly of signature because same.
Xie, Keping: This example improv the new mass and the low environment, no, no mission and goals so regions which one to 1010 gv another the mix and welcome Paul I found 200 minus six.
Xie, Keping: So, with different setup under compared to existing in in our chief visionary found common system, as we can cover some news new term in her space.
Xie, Keping: So so so this let's summarize yeah, this is a DVD composer along this promoted K and this disgrace vertex promoting decay, we can probably sensitivities come comparable compared to the easiest in for the lot you learn mosler large you have another master under lovely hires.
Xie, Keping: mix the angle in the numerator ma lower level mm per month and the lumix tango we can use the magnificent HR to probe a new parameter space region.
Xie, Keping: is so so that's our magnet Plaza so last one we just to just to just to one and.
Xie, Keping: Then towards the promise embrace everybody K, because so they're having a difficult time decay into some mix missing a missing part documentary so.
Xie, Keping: So this is just a charleston whiskey issue i'll be at the at the at the moment, yet we also saw consider about this nature to comment to say, this is a whole lot you, we are sensitive, you can go.
Xie, Keping: So this one, we found that is largely dependent on the system system, because how far how bad or we can go.
Xie, Keping: So you've really considered about in this is the rule system naked, we can get a comparable sensitivity, based on this signal party, we can have we can model will control bar this system system system and again point 1% 1% some degree we lose sensitivity, based on this channel.
Xie, Keping: So let me conclude them, but he SA T will open up a new acoustic frontier, but we also need to consider about the bsm starchy.
Xie, Keping: So we take there's a yeah there's to have an everton uber have a new service model to pop up window displays vortex so we can cover some new parameter space with a few gv rain masculine.
Xie, Keping: A button for the promise archie we can, and also to get a comparable the, the main problem compared to the existing searching.
Xie, Keping: So so with this study will inform us about the future, the as a deterrent designed specially powder this tracking system for authorities to displace verse happens.
Xie, Keping: Of course there are so many other possibility to pop or which I need to this reference here so so let me just stop here and take question.
Federico Leo Redi: This is brilliant 15 minutes and 02 seconds so Questions anybody.
Federico Leo Redi: Have a question actually so, can you go to slide the tears five, for example, my question is.
Federico Leo Redi: Have you can see there, the case of my ohana that for, for example, charger current violation or you have.
Federico Leo Redi: Seen Simon leptons that you could use in order to reduce the background and also Have you considered coupling to the towels because surely here you are competitive, but the face base is very crowded, but if you move to the coupling to the towels then that's not the case.
Xie, Keping: For the compliment to the.
Xie, Keping: tall you mean, this is a heavier left on big company with a towel or.
Federico Leo Redi: yeah exactly.
Xie, Keping: Okay, for that one we we.
Xie, Keping: We have do some premium or study but we didn't found the advantage, he he compared to the existing searches so so we didn't emphasize that direction in a in your your another word say that there is a load of anti to problems are parameter is with his machine.
Federico Leo Redi: So you can you repeat the last book.
Xie, Keping: I mean.
Xie, Keping: In for this.
Xie, Keping: course, this is the, it is the.
Xie, Keping: Last one tongue your tongue no assistance.
Xie, Keping: initialize so it's very sensitive to their own flavor and so that's why we focus on this, the left one cup to this and you know have 11 on for others a chance now.
Xie, Keping: You mentioned this couple towel so definitely this component can provide a sample, but there is no advantage compared to the existing team machine to pop.
Xie, Keping: can actually.
Xie, Keping: Say can provide a even our human ios az is the some others let kreider composite stronger prob compared to this yesterday.
Federico Leo Redi: Thank you.
Federico Leo Redi: I see maybe they take the question from Oregon, this is not a convener.
Federico Leo Redi: Your again, please.
Federico Leo Redi: Your again, we cannot hear you.
I see you're new to our.
Federico Leo Redi: Take a question from our but then yes.
Albert De Roeck: You can be earth good two quick questions, in fact, the hundred diverse temporal bone is for how many years of running.
Xie, Keping: I i'm I need to check slavery five to 10 years.
Albert De Roeck: Five to 10 years Okay, and the blood, as we have it here on frequency then.
Albert De Roeck: It doesn't actually say which.
Albert De Roeck: day that you show that is already showing through that reason, is this the recent.
Albert De Roeck: Data from the collider I think they go to lower couplings the law masters than what is seems to be excluded here.
Xie, Keping: We have included that they exist in searching and I call this the reason to exist in starchy under the for the project, the one can't go below.
Albert De Roeck: But even the existing one I think I mean existing since a few months or so seems to be going a bit lower than what we have is like 10 to the minus six around five or so, if I compare my blog so maybe you check once.
Albert De Roeck: If it's really up to date, just just for the sake of getting questions on what i'm a conference, for example.
Xie, Keping: yeah yeah yeah we have changed.
Xie, Keping: The most of the updated one coming from cms.
Xie, Keping: Okay yeah master at it, but it's not as goes too far, compared to the subplot okay.
Federico Leo Redi: Okay, thank you very much, I think we can take the question from European.
Juergen Reuter: Okay, just very quick in now, you can hear me right, yes.
Federico Leo Redi: Okay.
Juergen Reuter: So, can you can you say a few words about the status of the standard model predictions for the electron Ion collider So what is.
Juergen Reuter: Our the let's say predictions, I think the last calculations have been done for harrell like situations, are there any improvements or are these calculations still good enough to to get an estimate on the or a prediction on the standard model backgrounds for these processes.
Xie, Keping: Standard mode of background for this process, so we, we have a use this APP to left meeting what are some costs a which we can we can improve upper left next meeting, what are the data.
Xie, Keping: That one will not change our conclusion, based on a study for others processes definitely maybe we we i'm not sure, so how old.
Xie, Keping: Naka de de estimator minute because he Yes, he mostly cozy drum machine for COSI D study definitely do we need to that way well i'm not a for psm search.
Juergen Reuter: Okay, thank you.
Federico Leo Redi: Okay, thank you very much, thank you for the dog no move to.
Federico Leo Redi: It.
Federico Leo Redi: Now it is.
Albert De Roeck: microphone is on so.
Federico Leo Redi: Now you're muted.
Yes.
Albert De Roeck: Alright, so this last contribution for for this session is.
Albert De Roeck: different kind of paper than the ones we discussed.
Albert De Roeck: Before in this session, this is on.
Albert De Roeck: The White Paper, which was as you'll see commissions in in this no man's effort and it's about the present and future status of heavy neutral leptons so it's a kind of a summary from.
Albert De Roeck: What whatever we got information from and so maybe some channels you're not aware of, so in that sense, maybe interesting interesting and then these are the actors, which you see here that have worked on this paper and signed it.
Albert De Roeck: Okay, so as sets was commissioned by the neutrino physics frontier group, and it was done in concert with the energy from the air, and the.
Albert De Roeck: process from the at least there was communication and getting things done and i'm not sure we got all the information, but we got quite a bit.
Albert De Roeck: And the overall editors were myself and the shoemaker and you'll see all the characters for the different sections, we have in that paper from theory glider searches.
Albert De Roeck: More beta the case or nuclear as it became a nuclear chapter fixed target experiments or extract the beams if you want atmospherics and solar data and also from a cosmological bounce.
Albert De Roeck: And this is the archive for you can find the APP where the first version is on and the revised version or with with input we get, we will still.
Albert De Roeck: submit when when things calm down on all the input we get.
Albert De Roeck: In detail, not to be looked at, or stare that may be right now, but you can see, this is the contents of the paper it's about 70 pages or so with the.
Albert De Roeck: theory motivation production and some visions there on what they wish for the future to see collider searches takes a large chunk in that nuclear decay searches on nuclear processes so it's a.
Albert De Roeck: Smaller fraction than the extracted beams with the whole lot of process.
Albert De Roeck: projects going through and then the two other chapters which I will talk to now the the content of the baby is a snapshot at the status of the staff was 2020 the deadline for the snowmass papers was like.
Albert De Roeck: February earlier this year, so, for example, the latest results of atlas which game, you know, a month or two months later, are not at this present at the present time included there but.
Albert De Roeck: That it's more on the prospects anyway that we're trying to do.
Albert De Roeck: From the theory, I will not say too much mark was supposed to be around but it couldn't be couldn't volunteer for the talk here so but I will not go in too much.
Albert De Roeck: effort in here just saying one interesting plots which you may see time and over again coming times when these.
Albert De Roeck: Having intellectuals are discussed, and that is the connection with the standard model of physics, with the fact that we know we have escalations we have a mass pattern, with the active neutrinos and how that interacts with the channels in order to have, for example, agent else to be.
Albert De Roeck: A reason or an explanation for the fact that these active materials of masters and right now, if you look at the parameter space of the oscillations for the active neutrinos a map that on this.
Albert De Roeck: ternary diagram which is showing the couplings to the difference ninos of having a three nose to the.
Albert De Roeck: Like between on this side normalized to the sum of all the conflicts that is the three know so that's where they run sort of laying around shabana woman and between senior or above zero.
Albert De Roeck: Then, these are the regions which are allowed right now.
Albert De Roeck: Depending also if you have in a normal or the ring or an invert at all during in the neutrino case you heard about that yesterday about this question that we don't know the exact ordering of the trina trina masses, as we have.
Albert De Roeck: This, as it is today, but interesting if you see if you get too into June in the future, then this regions because of the better knowledge of this oscillation parameters will be actually coming into this kind of.
Albert De Roeck: ellipses you see here, which would be allowed for so the face space for the html parameters would be very constraints, so if we once you start measuring it, you can dial actually see if you observe this.
Albert De Roeck: Right handed the three knows if they are actually in sync with with with with explaining what is happening in the sector, so far.
Albert De Roeck: know that this is for a simplest model effort to active states and so forth BATs it's a start that shows you that there is this intimate connection, which is not necessarily to be forgotten.
Albert De Roeck: And by the way in the theory part they're stressing particularly also that we should go beyond the non minimal multiples so all a show for future and.
Albert De Roeck: which would include that we take one more active flavor at the time now we take just single active flavors in the channels to as benchmark points.
Albert De Roeck: But on the benchmark points itself, there was not much there is not much discussion despair that refer to discussions which happened in the.
Albert De Roeck: Physical be on collider studies or the phipps Forum, which I will show a little bit later, where in fact the theorists and the experience of working together to get more.
Albert De Roeck: benchmark points defined for the gelei that mom was not gonna say anything, because that is something we are quite familiar with, and this is just some of the plots and some of you seeing you're in this meeting, in any case of projections for, for example.
Albert De Roeck: The llc or for all the experiments which which are being told off as possible extra experiments to cover more of the face space and that's that's well known to us, so I don't need to preach to the choir scheme.
Albert De Roeck: That one thing I did observe, while we made this that for the high luminous theology for examples, there are not really.
Albert De Roeck: Prospects made by atlases cms or eligibility for that matter, as we have on many other bsm scenario studies that from the knowledge we have pleasantly we extrapolate that to the high luminosity with all the assumptions required.
Albert De Roeck: That for four H and else we actually didn't have that the only results, I found or film illogical status, which is good, to give you a hint where you're going but.
Albert De Roeck: that's maybe you, we would like to do something better on that in the experiments that that's a colony experiments think about that, and maybe that's thing, once we have the old Iran to analysis completed think about that.
Albert De Roeck: You may remember in the html group we had also ongoing developments on generate this for from the H and else.
Albert De Roeck: For the from the original discussion group which we have reported in these meetings and some sub meetings we had, and particularly work of phil and Richard default in that.
Albert De Roeck: We have included the state, as it is what is available in the document as well, so this is not the other final words and you're still development that further, but at least people see what's there and what the what what are possible things to come.
Albert De Roeck: Now for the extracted beings, there are a number of the prospects for projects disgusts like the ones we know well, like any 62.
Albert De Roeck: but also in ship, for example, but also the new proposal CERN which was presented last left on the longest particle meeting we had the number 10.
Albert De Roeck: and number of other experiments which not all of you, you may be familiar with most are in the industry or sector, but not all, and then that's now and J bar, for example in what they are, for you know the.
Albert De Roeck: Possible projections are for sensitivities, they can reach, and they have been thinking of working about that I give one explicit example here, this is for June.
Albert De Roeck: And the, this is what is now the official sensitivities of June, they haven't hadn't been done really within June, but there were findable logical studies for that and the now this has been done for and within the collaboration.
Albert De Roeck: I will not go into the details, you can find it back in the paper here, but that is for the most reasons configurations of the near detectors which we have.
Albert De Roeck: And for the program some targets profile, which we expect, which is six plus six years thing which means is six years old, the starting.
Albert De Roeck: intensity of the beam and then plus six year of the high intensity of the beam therefore different scenarios set what the different sensitivities off for the eight chanel's with dominant coupling to electron beyond doubt here.
Albert De Roeck: Or the flavor universal one, but that, for example, covers if you want, in its totality up to 12 years of data.
Albert De Roeck: This is an overview of projects where you can compare them, for example, you know just the lookup table, which is.
Albert De Roeck: giving you the beam types, you have the the detectors distances, the cave volumes distance from the damn problem some targets and not in the least.
Albert De Roeck: But that'll timescales a pure define scales, as they are today, so if you are interested in a particular regional face base or sewing you see this will that experiment cover it, this is giving you some more information at one plans or details, obviously the decks.
Albert De Roeck: that's, particularly for CERN I just know, two things here, there are the distant future, new experiments, we can have now ship is something which has been talked about for the last eight five to eight years or something.
Albert De Roeck: That adds you saw there was no date given here, because for that experiments that was not sort of favorably encouraged with the last.
Albert De Roeck: European strategy meeting, although it was certainly not said that should not happen was just said, we don't know where to find the money for that experiment.
Albert De Roeck: So for that experiment people have been rethinking of more cost efficient option for building the beam dumb facility, which was the.
Albert De Roeck: most expensive component in that, and there are now ideas, how it could be made more cost efficient, and to a large factor which.
Albert De Roeck: know I shouldn't name yet because it's not not terribly efficient but it's enough to be inhabiting under three discussion with similar if almost identical sensitivity else was in the original proposal, but maybe maybe a bit less.
Albert De Roeck: grant and what what one wanted to do what we're all the new things, want to do to build this experiment.
Albert De Roeck: And the second one is a new project and just reminded here, there was no specific talk on that in this meeting.
Albert De Roeck: But the guy and a friend, she did this gave a presentation at the last meeting open new detector.
Albert De Roeck: which would be sitting or, this is actually decay volumes big spectrum either, and the beam comes from this side through it and it's sitting next to.
Albert De Roeck: me 62 so it's an off axis experiment, but benefiting from the high rate and probably target you get connected with any 62.
Albert De Roeck: that's is at the moment of an expression of interest, which has been submitted to the comedy here and it's now with the referees and you know that's also if you see it may happen if it happens it's something like 10 years from now, to build and approve and finances so forth.
Albert De Roeck: Now, new which are in this paper are are with all these projects, and which I mentioned before, for these extracted beams and all the works being done.
Albert De Roeck: that the new sensitivity curves are being given a days are being plots blocks on such plots and you see just as usual, the compliment guarantee.
Albert De Roeck: That is being probed by by June, which is the green line which you see somewhere here, maybe not so good, and this 162 ship and shadows for the different theories, if you better, for example, for the different projects.
Albert De Roeck: And you see, particularly that is a neutrino experiments are going to be good below the kale mass in that region here and then of course the.
Albert De Roeck: Higher energy beams take over, because the mystery know experiments typically have only a low ish energy beam long targets want low for ship it it's it's for you it's probably hundred gv it's nothing compared to the 400 TV, for example.
Albert De Roeck: And that's the same for the bow so you can look at that, at your leisure So these are now sort of like the newly released plots for that, with all this new information and.
Albert De Roeck: Then let's in the last few minutes is something on something else that is searches for html, for example, in the very low mass range it's means up to maybe then a movie or so and below starting from the kV level.
Albert De Roeck: And then we come into the nuclear processes, particularly like a beta decay searches were like Catherine is doing now, Catherine measures, the beaten the case back when in fact they're only interested in this part here to find out if the.
Albert De Roeck: electron the three and a half miles or so, but in the spectrum itself either would be html so you could get the kinks.
Albert De Roeck: And so well that's something that don't normally spend a lot of time measuring but if they they will at some point in time when they're exhausting this component here and now they take test measurements and be looking for these kind of things.
Albert De Roeck: And a particular upgrade of Catherine was called tristen would be able to mention differential he would have a.
Albert De Roeck: Good sensitivity in that region, so that you could search for from search for this kings in some interval between few kV till about almost 18 kV, which is the endpoint which I have here.
Albert De Roeck: For four H and Nelson this would be like the truth, the Catherine sensitivity itself compared to exclude the bounce already in that region that would be the system upgrade one which would start in 2025 or so.
Albert De Roeck: Doing can also play a role in here, looking at.
Albert De Roeck: Our GM 39.
Albert De Roeck: atoms that are the decaying and if you don't do anything special for the triggers for that this is we're doing would sit.
Albert De Roeck: In the coupling and mouse you go to higher miles, because the K value here is more like 850 400 million something like 400 kV here.
Albert De Roeck: And if you do something special on the triggers and the analysis which is gross coming at the price, you could go like two orders of magnitudes further down it couplings measuring that and there are a few others, I will don't.
Federico Leo Redi: know now i'm.
Albert De Roeck: sure I will love few others, which I will not go in detail, that is, the electric capture, which is like a reverse be that the gate process reactor based what the caller ID type of events verse be that the case.
Albert De Roeck: And the three nodes be the material is Peter double double beta decay also can give you information on that anyway, these blocks are you in that, then I think the final thing I talk about the natural adrenal fluxus coming from either neutrinos from the sun or from the.
Albert De Roeck: The atmospheric neutrinos which we have you have three kind of mechanisms that can lead you.
Albert De Roeck: To having agent else either they come directly from the neutrinos in the shower or you can have such a weather cold double bang events like you can.
Albert De Roeck: Also, look for 4000 and ice cube but with large distances and look for for that now using these techniques and one isn't the same one isn't up scattering that that the three know interacts with with the nucleus and grades.
Albert De Roeck: Or, as an exchange student you get the heavy nutrition three know out, so this is for what ice cube could cover.
Albert De Roeck: From these double banks that they have from the atmospheric neutrinos, and this is already something Barack see no measure is green curve here, so in this new region where they could exclude.
Albert De Roeck: Under certain models, this is not a simple seesaw model, but the double bottom constraint model for each and else to be found, so this is actually new region call for them from solar on the three knows by analyzing the Baltic Sea, no data.
Albert De Roeck: The final thing, without giving too much detail on that, on the cosmological and astrophysical.
Albert De Roeck: Results is there isn't updates of that, with all the new bounce in here updated overlaid is a picture made by Marco with the reaches which we had before, from the different in the lighters and so that's.
Albert De Roeck: That this is as good as we know it right now, according to our group district was working on that.
Albert De Roeck: and put since time is over, I will not go into the details here at the end, this is no mass paper, it gives recommendations and the recommendations, which are all I mean in the in sort of the beholder for what we are thinking certainly that.
Albert De Roeck: You know, eight channels and longest part of the Spikes stands for the should be a key part of experiments baseline physics program that's particularly goes to.
Albert De Roeck: The neutrino experiments which do not have this as a baseline but also Jay was discussing this yesterday.
Albert De Roeck: Future collider facilities should, from the start and see the requirements for such things you know, we are all working on that, so we have it here, because this is being used for for the snow miles in both.
Albert De Roeck: Then okay what I said from the theory, we should starting to think of scenarios where speech goes beyond the single flavor dominance, which we do right now that's for the nuclear experiments which we encourage and.
Albert De Roeck: case of discovery which we all would like to anticipate, for we all should think ahead in what actually we all need to measure it and how are we going to measure it if we're at someday so lucky that we actually see a thing.
Albert De Roeck: that's it's while I want to give us a summary of that just to say that.
Albert De Roeck: If this is the last day of this workshop, and if you're already thinking what to do with your time and would you like to have a new workshop, there is a workshop coming up.
Albert De Roeck: At CERN, which is the fifth 2020 which also mentioned as a benchmark discussion forum wherever that's happening at the moment.
Albert De Roeck: And there is, for example, so, while there are three main topics that have and one is the hopefully flavors that connection to the active neutrino physics so you're going to have more than that and i'll stop here thanks.
Federico Leo Redi: Okay, thank you very much, we are quite ahead of this kit know behind schedule, so if there are no questions from the audience.
Federico Leo Redi: I will refrain from asking questions, and I think we can conclude the session here, thank you very much for everybody that participated it's very refreshing to see so much new stuff on a chance, so there is a coffee break now in theory that should be 15.
Albert De Roeck: minutes.
Federico Leo Redi: They let the.
Federico Leo Redi: Next session decide if they want to squeeze me so i'm not thank you very much, everyone.
James Beacham (he/him): But note that the first talk the next session is also about a chanel so it's kind of a nice continuation.
Albert De Roeck: It isn't it alright.
Federico Leo Redi: So do we give you five minutes and really convenient for.
wins.
Margaret Susan Lutz: No as.
Margaret Susan Lutz: going to come back in 10 minutes excellent.
Federico Leo Redi: Okay now it's up to you just speak.
Margaret Susan Lutz: Come back in 10 minutes.
Albert De Roeck: All right.
