WEBVTT

00:00:00.000 --> 00:00:04.000
So this session, actually. Despite the generic title adopt is something specialized on looking at recent information on the heavy neutral abdom Bible studies, which have been promised and serve it.

00:00:04.000 --> 00:00:06.000
And now we're even regarding it.

00:00:06.000 --> 00:00:11.000
And so we have a number of thoughts that complex here.

00:00:11.000 --> 00:00:25.000
So, the first talk is by renew, as we saw, and or as we already discussed within is going to talk about some predictions for the FCC ah ah so you can share your screen, please.

00:00:25.000 --> 00:00:28.000
Okay.

00:00:28.000 --> 00:00:32.000
Can you see my screen. Now, we do.

00:00:32.000 --> 00:00:37.000
Okay, so shy starts.

00:00:37.000 --> 00:00:44.000
Full Screen splits okay we hear you well. So, again, you're you're all set. Let's go.

00:00:44.000 --> 00:00:53.000
So, this is an invitation, and ready to give a talk, and has this kind of washed out of the community.

00:00:53.000 --> 00:01:09.000
So I'm awaiting from the University of Science and knowledge, and today I'm going to talk about how neutrinos as FCC associations in our model. So this talk is mainly based on paperless just published at PRD.

00:01:09.000 --> 00:01:15.000
And I want to send my father is such a colleague and friend devilish.

00:01:15.000 --> 00:01:35.000
Okay, so let's start with neutrino mass. We all know that to the finals and neutrino mass is between observations pyramid is a great breakthrough in the particle physics, because it pointed out, set the standard model is not complete, because cinema does

00:01:35.000 --> 00:01:38.000
not create a new channel masses.

00:01:38.000 --> 00:01:51.000
But not only set we finalize that and Trina was is very tiny, you only have EV or neutrino mass, but as a formula as hell a memory leak. So 06 management gap user.

00:01:51.000 --> 00:02:03.000
And also the neutrinos as only mutual formula. So we might help question. Okay, maybe the channels have different original masses.

00:02:03.000 --> 00:02:12.000
So, now we can review that, okay, what are the must mechanism in the standard model, in some.

00:02:12.000 --> 00:02:37.000
So, a sink in general engage a theory we have two kinds of mask mask mechanism so first one is, Iraq, a must turn this is very general so you have a left right from your with the Hicks, and all also send will from your hands console must turn, but also

00:02:37.000 --> 00:02:54.000
be this one right hand for me always is on, and the particles so it must be neutral from you say can, because this is my one must I must turn.

00:02:54.000 --> 00:02:58.000
So we saw. So driving on muscle houses problem.

00:02:58.000 --> 00:03:11.000
It was a neutrino channel hat, as this as a seminal point has is throughout most terms. So we find one very strange thing is that it is you call communities going to be very small.

00:03:11.000 --> 00:03:19.000
It's because it's very small set up. but when you have the hugest potential like 200 GG.

00:03:19.000 --> 00:03:32.000
So I really call it race war and we don't make that mistake is our natural everything, Eric Cartman should help the similar in order one for ideal.

00:03:32.000 --> 00:03:45.000
So now we want to six days. So one possibility is that it was a nutritional Mars, I introduced by both of them. So we have, how these kinds on a mass matrix.

00:03:45.000 --> 00:04:02.000
So the zero MD, MD Mr. So this is so called the system mechanism is because the way down this muscle matrix, you how two months it says, so the first one is going to be inverse proportionate to the second one.

00:04:02.000 --> 00:04:23.000
So, since we, we know that the first must identities were really tiny. so we can, we need another very happy. Mass psychosis. So we call this first one surviving Trina was the second ones and having treacle syrup for evil we making this Mr so Moran she

00:04:23.000 --> 00:04:33.000
wasn't very happy. We can still making this direct mass to be like, although TV, which means as you call it is natural gas.

00:04:33.000 --> 00:04:50.000
So his assets, we can naturally display means economist also oversold tryna was, and this so called a seesaw mechanics, and the simplest series of new NSF modal.

00:04:50.000 --> 00:05:06.000
Okay, so now we say Sachin, you can will experience a tiny Soul Train on Mars by adding a wind tunnel, so called the type of yc so now we can see how to, how to test it proves that we are true.

00:05:06.000 --> 00:05:31.000
And so, the most terrible way is to find sir, Ryan Chino, and most powerful most promising environment it is at collider was the LCC and SLC was a production process channels including has channel production via as a detailed study of autism, was it was

00:05:31.000 --> 00:05:45.000
All via some to channel by Vf process, process, and we are going to show that all those is overseas processes normally going to the probe the season the canister.

00:05:45.000 --> 00:06:08.000
That is because all of this process, the penny owns the attic start mixing, and we are going to just use now. So like, cause so neutrinos has likely has mass audiences and the flavor it says, and the NZ mix between jars and recording records and mixing,

00:06:08.000 --> 00:06:11.000
as the artist from stereo mix.

00:06:11.000 --> 00:06:35.000
Okay. And if you must, I must measures, and you will soybeans Addison scales at it ceramics, it is approximate to the ratio between the sunlight between all must I must end so having tryna last season we knows the mantra was the only EV and running trail

00:06:35.000 --> 00:06:47.000
we are looking for is as colliders, so we should have muscle gv. So this means as a space square is very timely is going to be smaller than 10 minus 10.

00:06:47.000 --> 00:06:52.000
So you can see here is a current summary always.

00:06:52.000 --> 00:07:12.000
So, the name is old, I was having trouble searches. So you see that this black dotted line on the title I see so aeration relation, and always is a current flooded searches were including some proposed one on notice going to pro promise that I will see

00:07:12.000 --> 00:07:18.000
means that we need to look for us for that channel to process to yc so.

00:07:18.000 --> 00:07:34.000
So, what we come to realize that it was around tree No, we are copying to other page, then it can produce a virus on a case by case. So we choose the gauge to be the demon out.

00:07:34.000 --> 00:07:38.000
Okay, which is icing ism while simplest model.

00:07:38.000 --> 00:07:54.000
And if we do such one day she can also making this time I see so mechanics more natural. Because now, so my run out of material was is going to be produced by a spontaneous which are breaking all this you will engage.

00:07:54.000 --> 00:07:58.000
So like us, as cinema x. Ok.

00:07:58.000 --> 00:08:20.000
And then just canceled. so good to have the search capacity as colliders. So we see here is, as is a promise. And here is a copy. So as I was see a sink is very powerful two purposes, like some TVs a prior.

00:08:20.000 --> 00:08:41.000
So of course on Tuesday points the current mixing all the companies tend to want to deserve very small, but was How old is your machine, we have a timer TV Christianity, and we are very promising to pro have properties as a plan like with a muscle more

00:08:41.000 --> 00:08:42.000
than five TV.

00:08:42.000 --> 00:08:48.000
Okay. So indeed, it shows a cross section this figure.

00:08:48.000 --> 00:09:08.000
So you see that for like five TVs a prior to access issues is going to produce the hunger time more sensitive than LC, and even with a very conservative benchmark cup pitch, good copy and just you how the one venture bottles, say prime.

00:09:08.000 --> 00:09:17.000
So as a product relates to detain to appeal right hand trainer as around you know what he came to give us some and multiple finances.

00:09:17.000 --> 00:09:23.000
Okay. And since the brush Rachel was a pathway to the rock right trace.

00:09:23.000 --> 00:09:34.000
Where is peaceful life. So we are still going to find these hundreds are having trouble frost actual heavy as a prime. Okay.

00:09:34.000 --> 00:09:43.000
Well, since we talk about the production was having trouble. Let's talk about signatures. Okay.

00:09:43.000 --> 00:09:52.000
So, yes, this. So, today we are talking about how Rp. Okay, so we find that having to train on, indeed.

00:09:52.000 --> 00:09:59.000
Okay, it's because having a triangle. A always the case of biases sweep it Okay.

00:09:59.000 --> 00:10:12.000
Okay, so, so the a new to the cape is on pitch bozo skaters, and they can either sit for electronic as is a seminar atomic.

00:10:12.000 --> 00:10:22.000
And we are going to show is that due to the system mechanism, you have this very small, tiny

00:10:22.000 --> 00:10:37.000
at this round mixing. Okay. and because of this mixing. You are sees as decay last old having trouble is going to be like meters. And within this gv a scale.

00:10:37.000 --> 00:10:38.000
I hear.

00:10:38.000 --> 00:10:58.000
I need to introduce about this new trail. This sister band, because we know that. and we know that it's there are at least one neutrino Christmas between the 1.4 y EV and it was really sad because we know that it's there are the habits neutrino is going

00:10:58.000 --> 00:11:19.000
to be larger sensor support for yev, because we have this animal spherical and channel My difference, and also the emotional need to be more than one way to point three because the product collaboration to the essential will from Sandy, Sandy observation.

00:11:19.000 --> 00:11:36.000
Okay, So, so basically a seesaw will will point our status or be square it's going to be below 10 910. Okay, so every single day. As always, is also fun because you can you can have a neutrino, which is a lot lighter than having trouble.

00:11:36.000 --> 00:11:42.000
So I do okay, Thomas has which you know had very large, the cadence.

00:11:42.000 --> 00:12:04.000
So if it's a, having to know has by Mitchell detailed as we need to will see it if you From today, because normally I singing cry there's research particles inside of fertile locate the now because it's a key indicator as a microscopic is the IP.

00:12:04.000 --> 00:12:15.000
So we are going to detect some insights. Got chakra system or camera system, or even some mail system.

00:12:15.000 --> 00:12:16.000
Okay.

00:12:16.000 --> 00:12:26.000
And this console having to know, how are very unique because of his he came from very happy is a prime. Okay.

00:12:26.000 --> 00:12:44.000
And this is very powerful. So is chemically medical distribution is very different compared to the house. See, we see is that soon as he's having Trina is going to have very large team.

00:12:44.000 --> 00:12:57.000
So, if they are light, send his final state, many time us, me and Andrew and jet is going to be very coordinated. So we need some spattered should limit.

00:12:57.000 --> 00:13:03.000
So I'm referring to the paper had her rosary at all.

00:13:03.000 --> 00:13:10.000
And she has just published the archive for the detail analyzes. Okay.

00:13:10.000 --> 00:13:16.000
So, also we have down the searches or how many triangles.

00:13:16.000 --> 00:13:35.000
And as x age. So we have done two different process we have not only dancer, be myself a channel but also the cinema channel. So the channel means as having trouble are produced by as detailed as a prior cinema one incentive is produce advisors that was

00:13:35.000 --> 00:13:36.000
on.

00:13:36.000 --> 00:13:49.000
Okay. And here we also show incentives, there are some curve has enabled TV. This means has to go new particles searches and curves, so control which means they are promised search.

00:13:49.000 --> 00:14:02.000
So we see that. Also, LLP search happiness activity, compared to the problem why, because the problem we're how we're live sending more than that. Right.

00:14:02.000 --> 00:14:14.000
And all the demon sale channels are brothers in cinema the channel because they don't suffer from this, an inverse proportional to the city square. Okay.

00:14:14.000 --> 00:14:33.000
And then component awesome, we can pull the large perimeter space, of course, having a triangle, and the world we find all set. Okay, discounting op search you can Pro, a very large primitive space folks at yc so so here in the conference some time I

00:14:33.000 --> 00:14:43.000
see so band, and even below it. An event for this process we didn't cover metals and, if so having, you know, having officers they're going to be prompt.

00:14:43.000 --> 00:14:55.000
Having offices, they're going to be prompt. Okay, so our conclusion is that you can test the see so as FCC a certified fish portal.

00:14:55.000 --> 00:15:19.000
Okay, So this figure is very similar, just finances is new JJ, so seminar tonic. So because you have multiple jets. So, the price ratio is larger, and you get a better cross section and appropriate lower mixing everything is very similar.

00:15:19.000 --> 00:15:35.000
And also on one asset to having trouble catalog to be to to rise, you digitalize you're going to kill us, and to Jess, and you're new to social fires and Muslim the case.

00:15:35.000 --> 00:15:38.000
and it's going to be performed at the ship.

00:15:38.000 --> 00:15:42.000
OK, so now we come out solution.

00:15:42.000 --> 00:15:53.000
So, neutrino physics is very interesting. I think the most important why is that we don't know the regional channel mass.

00:15:53.000 --> 00:15:58.000
So I think type I see so is one more thing this solution.

00:15:58.000 --> 00:16:14.000
And we want to will test them colliders be caught Burton, but it was a hand to produce fires and who can already probably tomorrow So, so we come.

00:16:14.000 --> 00:16:24.000
So we need some additional engage and rescheduled care additional poison visor a digital cash flows.

00:16:24.000 --> 00:16:29.000
And we're sure that this promotional homes around channel.

00:16:29.000 --> 00:16:40.000
And if we serve some fires out op China, signatures sound we are going to the task at hand yc so as the FCC church.

00:16:40.000 --> 00:16:46.000
So I think this end of my talk, and then many sex.

00:16:46.000 --> 00:16:51.000
Okay. Well, thank you very much for this distinct contribution.

00:16:51.000 --> 00:16:59.000
And we're gonna take a few questions. A quick one. In fact, on your slide 10.

00:16:59.000 --> 00:17:07.000
Did I understand that this blue region within the rectangle is everything you dig in there.

00:17:07.000 --> 00:17:22.000
Yes. For cross section so so use you mean that's a displaced produced the three know that the case and you will see it in your acceptance or me you will take it as your acceptance right now.

00:17:22.000 --> 00:17:34.000
Yes, so I see so I'm just roughly considered that all the nutritional decay inside this volume.

00:17:34.000 --> 00:17:44.000
Okay, because it's not quite optimally instrumented to do that but but at least find this gives you the maximum type of, of the case you can see and that you use for your.

00:17:44.000 --> 00:17:48.000
Okay, good. Just I understand, thanks.

00:17:48.000 --> 00:17:49.000
Phillip.

00:17:49.000 --> 00:17:56.000
Thank you very much and this is very interesting. Can you go to slide 20. Oh, please.

00:17:56.000 --> 00:18:03.000
Yeah. So when you look at the region between above the child threshold.

00:18:03.000 --> 00:18:10.000
So one of the king cruise ship is in below, six, seven, of you.

00:18:10.000 --> 00:18:25.000
And you can see them the different production modes to study. Hmm productions in FCC, for example, coming from bs or Pale Horse confirmed case.

00:18:25.000 --> 00:18:44.000
Anyway, was to try to explore lower versus staying out for a dancer, as LC. So, yeah, so having trouble reading this master SV going to dominate and produce spice, based on the case.

00:18:44.000 --> 00:18:54.000
And I haven't seen anyone do you actually have to say church that was going to be different.

00:18:54.000 --> 00:19:05.000
I'm not sure I mean it requires a different study this is clear but it should be possible. Okay. Yeah.

00:19:05.000 --> 00:19:22.000
Right. Thanks. Is there quick final question. It's already making minutes so we can. Yeah I know, I know, just that the convenience, don't you know monopolize all sessions, but not in this case.

00:19:22.000 --> 00:19:24.000
Thanks again.

00:19:24.000 --> 00:19:33.000
And then we now go to get your modem be nice, which I think is around, and his talk is there.

00:19:33.000 --> 00:19:35.000
Hello.

00:19:35.000 --> 00:19:36.000
Hi there.

00:19:36.000 --> 00:19:38.000
So if you can share your screen.

00:19:38.000 --> 00:19:48.000
Awesome.

00:19:48.000 --> 00:19:51.000
Yes. Can you see it now.

00:19:51.000 --> 00:20:00.000
Okay, we see it over here you and you're gonna tell us about neutral leptons interacting with singlet scalars, take it away.

00:20:00.000 --> 00:20:07.000
All right. First I want to thank the organizers for the detention and I would like to thank everyone for coming.

00:20:07.000 --> 00:20:18.000
Yes, this thought will begin with this very feminine to leopard in the world, nobody but let me talk a little bit about it.

00:20:18.000 --> 00:20:30.000
And then, How we technique that we use to to reproduce the limits from Delphi belt in terms of experiments.

00:20:30.000 --> 00:20:42.000
And then we'll tell you what happens when we are like service traders that come the couple's to do the HTML, and also mix with his. All right.

00:20:42.000 --> 00:20:51.000
So, yeah, so, so we're aware that neutrinos are massive and Austin's our the end of the last millennium. Right.

00:20:51.000 --> 00:20:55.000
But the question is how do we know that they have mass.

00:20:55.000 --> 00:21:00.000
And this is the short answer is digital solutions, right.

00:21:00.000 --> 00:21:05.000
This simple explanation to the side which is no problem.

00:21:05.000 --> 00:21:16.000
And that requires, just to the masses. Right. And also they have different masters, and how they get their mass, you know, the Higgs mechanism, is it extra dimension.

00:21:16.000 --> 00:21:18.000
Is it something else.

00:21:18.000 --> 00:21:27.000
I don't know but I think nobody knows But the web will be the proposals that need to be tested in the laboratory.

00:21:27.000 --> 00:21:44.000
Right. So here, I'm going to talk to you about system integration, very quickly. You know, we've been sampled, which is offer the new standard model single preferred medium that mixes with the legendary exclusively with the regulatory, but this case will

00:21:44.000 --> 00:21:53.000
help this mess matrix for for this in this original trigger a new initiative basis. Right.

00:21:53.000 --> 00:22:05.000
That will allow us to compute the meters, we don't have mass equals zero anymore. We have to master one, there is this small mass and when this heavy mass.

00:22:05.000 --> 00:22:21.000
Right. But we want to know what will be, who has this mass, right, and the light state is is mostly the little triangle. Right, and small fraction of the new super firm.

00:22:21.000 --> 00:22:29.000
Right. And then, but then the most massive state defender one is mostly the new the new state. Right.

00:22:29.000 --> 00:22:33.000
In what characterizes your physics here.

00:22:33.000 --> 00:22:49.000
Is this ratio between these two unknown parameters, right there. So, since they tell us what the physics there.

00:22:49.000 --> 00:23:11.000
And we can just simply call it, mixing a book and experiments. So this I presume to understand the experiment at all of us to experiment on this, because there are so many victories including with personal stuff that I know expert.

00:23:11.000 --> 00:23:30.000
Right. So I just want to say that we think of electronic Muslims colliding, right, then it will produce much particles, like the the the right energy, they can produce these zeros.

00:23:30.000 --> 00:23:49.000
Now, it had drones and between us. Right. And, and I respect this, the physics of manifest. You know in the mixing with with uh with likely dreams and and produce and produce this kind of little lemon, and it's going to let them go.

00:23:49.000 --> 00:23:51.000
Actually the key for week interactions.

00:23:51.000 --> 00:24:00.000
Like this new direction or church, not just currents in produce personal left on the trailer supports only have a nice and No.

00:24:00.000 --> 00:24:18.000
Nice and No. Okay, so we can use this, this, this, this experiment to put constraints on the, on the mixing of the HTML right of the deals that I want to see with Furman with the industry's.

00:24:18.000 --> 00:24:19.000
Right.

00:24:19.000 --> 00:24:38.000
And that's what what's showing this fear, on the right, which is the mixpanel as a function of the mass, right, everything there is about this, this line is rolled out 99% confidence level with the Federation, and we did in his work was to add the same

00:24:38.000 --> 00:24:59.000
but for me it's a similar model similar scale. So, like the others. So we have this secret scalar and this single term. And both of them interacting with would change the limits on on this mixpanel.

00:24:59.000 --> 00:25:14.000
Because, first of all, the singlet can mix, if you can if you can mix with the Higgs boson, then it can hurt into the cake and the painful person, as a fervent, there are, there is for example experiment, what is it looks for.

00:25:14.000 --> 00:25:15.000
Right.

00:25:15.000 --> 00:25:25.000
And so this thing that could be faking, you know, could be mimicking the case of the, of the child of the week case. Right.

00:25:25.000 --> 00:25:28.000
So we want we wonder what happens to this.

00:25:28.000 --> 00:25:37.000
I will bring very briefly describe how we, the method that we use to regulate the snippets for the first way, we got here that we can reproduce this limits.

00:25:37.000 --> 00:25:51.000
And we're but by, and within by the number of events by who this is the number of verticals. The weather was bye bye ru probability through probably just actually one of producing detail.

00:25:51.000 --> 00:26:05.000
And then, of the internet came into what is look for, for a particular dictate from this particular experiment, but I also wanted to know if we can reconstruct this event.

00:26:05.000 --> 00:26:06.000
Right.

00:26:06.000 --> 00:26:16.000
Right. experiment where, where the detector is far from the target, like it's showing this finger at least indeed. This is the last formula.

00:26:16.000 --> 00:26:25.000
If we have the Delphi up conditions inside detector. Right. And then he will be zero, and we get different

00:26:25.000 --> 00:26:38.000
The scope change the results with the rest of the fraction was events actually agreed we met a great person what ankle good, never, never point of this grid, this quantity.

00:26:38.000 --> 00:26:45.000
And then we converted to the we compared to the Polish result of the Federal probation.

00:26:45.000 --> 00:26:57.000
So we just, we first plot contours of this, or this fictional event, right with it would be for 10 to the minus five and 10 to the minus several and we saw okay this close but not good enough.

00:26:57.000 --> 00:27:08.000
And then we found that for 10 to the minus six, personally, we get these red lines, and our woods, you know, but still have a problem in the legend for later.

00:27:08.000 --> 00:27:18.000
Two years later he knows. And then, for the first time around 200 centimeters, we get, you know, this result of blue.

00:27:18.000 --> 00:27:25.000
The way we use for now, as the as the limits from which case for Africa.

00:27:25.000 --> 00:27:32.000
With the same for for America. We've had some small discrepancies with with with all results.

00:27:32.000 --> 00:27:43.000
And we'll talk about later if someone's interested. But here, want to raise two questions here to us when we assume that there because things are going to change.

00:27:43.000 --> 00:27:56.000
Who's going to win with the gates which are already the case you know the original or the new channel, the story the case you know the secret, and in the tree, and the tree.

00:27:56.000 --> 00:28:01.000
But the win. So we want to fight these

00:28:01.000 --> 00:28:19.000
questions over here. And now, okay, right so who wins what's going to happen, that I want to be more educated inside the doctor, or outside you know what's what's going to happen, going to happen there with original Delphi formula that we have here, we

00:28:19.000 --> 00:28:38.000
can get the limits the audition for blue light, a light blue for for for Delphi experiment. And we assume that this will change the format just a little bit, you know, the production of the editor and the length, and the length of the channel will change.

00:28:38.000 --> 00:28:44.000
Also, there will be increased by, with each other.

00:28:44.000 --> 00:28:45.000
All right.

00:28:45.000 --> 00:29:00.000
So, this is the most interesting part, which is why we're telling you the results in blue without the limit we're with pure with with directions.

00:29:00.000 --> 00:29:06.000
And we're assuming that this particular mixing with with a fixed most on that.

00:29:06.000 --> 00:29:08.000
As far as I'm mixing.

00:29:08.000 --> 00:29:15.000
There's no law by by experiments, before and it couples to the originals.

00:29:15.000 --> 00:29:21.000
With this freedom for strength that I'm showing you right.

00:29:21.000 --> 00:29:35.000
It will change the limit opens the flower to space from them when they submit is medically allowed to reproduce, like this case, it's a AGV sit with that you know stars are here.

00:29:35.000 --> 00:29:43.000
And then the prompter space opens, because again, approaches the

00:29:43.000 --> 00:29:49.000
limit from from from with the case because the production is suppressed. Right.

00:29:49.000 --> 00:29:53.000
Yeah, that's pretty much

00:29:53.000 --> 00:30:07.000
all of this is for traders. In the case of your mixes. Right. Well, we only look for electronic gear or Tao, this case.

00:30:07.000 --> 00:30:08.000
Right.

00:30:08.000 --> 00:30:22.000
So we've got that for many other configurations for different masters of the similar spoke with the ABB to arrive at gv know, and for small businesses which was explosive.

00:30:22.000 --> 00:30:25.000
And, you know, sometimes we have.

00:30:25.000 --> 00:30:31.000
We opened up the space a lot, sometimes not so much as sometimes we had personally closer.

00:30:31.000 --> 00:30:43.000
But, you know, that's a result of everything similar to the, the result of difficult to see you know we didn't make it up.

00:30:43.000 --> 00:30:51.000
We didn't say for bill right future for this is with electron, and from noon.

00:30:51.000 --> 00:30:59.000
And then the thing here is that for Bill, we always opened up our space.

00:30:59.000 --> 00:31:15.000
Because, you know, we have the same way that if it mimics the, the case of the original, right, then we can change it the limits can open or closed if I'm a space where you just taste the serial killer decay into what looks for which are.

00:31:15.000 --> 00:31:18.000
We're violence, and laptops together.

00:31:18.000 --> 00:31:34.000
laptops together. Right, so they tend to get on the plane to the top. So that's why I like this. They're likely because of the same, and the private space, open the space

00:31:34.000 --> 00:31:39.000
for time was the perfect okay for turn.

00:31:39.000 --> 00:31:47.000
We've had something similar to what to what happened to just buy some space open and sometimes it's closer to know.

00:31:47.000 --> 00:31:58.000
Sometimes we have with the original because the secret. Now, can decay and where it shouldn't be supposed to be anything.

00:31:58.000 --> 00:32:11.000
And that would actually give a signal that we were we interpret us build the company of the, of the agenda with with active metrics.

00:32:11.000 --> 00:32:13.000
So,

00:32:13.000 --> 00:32:16.000
so Okay.

00:32:16.000 --> 00:32:33.000
And these are that yes we can open the parameters face in many cases with, like to the scanner, or recommended you know we can mix it in the cup the role of the other music with a fix.

00:32:33.000 --> 00:32:37.000
We do that this work but it's open.

00:32:37.000 --> 00:32:43.000
And also, this method is, you know, saves us a lot of time, if we didn't have to do any specifics on what he got simulations that we don't know don't know what to do so.

00:32:43.000 --> 00:33:12.000
We didn't have to do any specifics on what he got simulations that we don't know don't know what to do so. That's good. And also, it can be used for other experiments, and only the one that was shown here, but for other things that may be interested.

00:33:12.000 --> 00:33:17.000
All right, thank you.

00:33:17.000 --> 00:33:34.000
Interesting contribution with them still sort of motherhood in my mind, exactly what the message is just for for for my health. So the, the limits you calculate, is that that is human you don't see any experimental signature of the singlet.

00:33:34.000 --> 00:33:50.000
Yes exactly, that's what this perfect thousand right so what would be the number of threads there.

00:33:50.000 --> 00:33:51.000
But if it's, you know, firstly you could you could try to try to detect a signal.

00:33:51.000 --> 00:33:52.000
Yes, that's events you lose because of it, they're going to a single day you don't observe that.

00:33:52.000 --> 00:33:57.000
Exactly.

00:33:57.000 --> 00:34:11.000
Exactly, yes. Okay, yeah, that's not what you, what what you discuss here just how our face space gets reduced by the goals that you have this extra singlet in the in the in the production.

00:34:11.000 --> 00:34:14.000
Yeah. Okay. Thanks.

00:34:14.000 --> 00:34:18.000
Hi, yes thanks again we'll just a quick question.

00:34:18.000 --> 00:34:28.000
This mixing is the mixing with the singlet. This is why it's in the independent of the, the flavor, as you said, Oh yeah.

00:34:28.000 --> 00:34:34.000
Yes, the mixing with the sort of do remixes.

00:34:34.000 --> 00:34:51.000
For instance here. Yes, you have mixing exclusively with electrons Reno's as you exclusively with new materials. Yes. And in your previous blood you had the train upper limits on the mixing with the light skater.

00:34:51.000 --> 00:35:01.000
This one yeah oh yeah oh sorry yeah okay yeah yeah yeah okay. Yes, thanks.

00:35:01.000 --> 00:35:07.000
Right, that's a good clarification. So, any further questions for them.

00:35:07.000 --> 00:35:13.000
Yes, thank you very much. So, assuming one wants to

00:35:13.000 --> 00:35:19.000
let me understand why did you pick their female and charm, specifically.

00:35:19.000 --> 00:35:27.000
Oh, Yes, we were interested in the Muslims from about below the threshold.

00:35:27.000 --> 00:35:28.000
Yeah.

00:35:28.000 --> 00:35:37.000
Below 10 gb, more or less. And so we started looking for, there are other limits from Atlas is us.

00:35:37.000 --> 00:35:39.000
Also competitive.

00:35:39.000 --> 00:35:43.000
We don't they're not competitive. That was the leading.

00:35:43.000 --> 00:35:47.000
Yeah, yeah, and

00:35:47.000 --> 00:35:54.000
perform the same exit size also with the, with those limits.

00:35:54.000 --> 00:35:56.000
I really good.

00:35:56.000 --> 00:35:59.000
Yeah.

00:35:59.000 --> 00:36:02.000
But yeah, of course the production mode.

00:36:02.000 --> 00:36:04.000
Very.

00:36:04.000 --> 00:36:08.000
And then you also have different production modes.

00:36:08.000 --> 00:36:14.000
From from the maybe you want to discuss on matter most. Because I think you do have to move up.

00:36:14.000 --> 00:36:19.000
Yes. Okay, thank you. Okay, thanks very much again.

00:36:19.000 --> 00:36:34.000
And you, and so we now go to the next speaker and I think it takes off.

00:36:34.000 --> 00:36:40.000
Yes. Can you hear me and can you give me a pro.

00:36:40.000 --> 00:36:53.000
Yes, so I'm trying to share my slides that works fine. Yes, maybe just try to make it as a presentation, and even bigger. Good. Okay. can I start. Yep.

00:36:53.000 --> 00:37:05.000
Go ahead. Thank you very much. Okay, great. Thank you for the invitation, I want to talk about having your treatments that future you bless you my name is colliders and this work was done in collaboration with you're going right there from Desi and Alexander

00:37:05.000 --> 00:37:14.000
Fijian escape from University of Horsell, and the paper, describing the whole analysis is available on archive.

00:37:14.000 --> 00:37:23.000
Let me start the presentation with a short introduction to the topic. As we know, there are some problems in this model.

00:37:23.000 --> 00:37:35.000
Basically, connected with, with some cosmological observations, I mean, this observations are the most convincing ones that there is something beyond the standard model.

00:37:35.000 --> 00:37:42.000
In some theories, we have these problems neutrinos are connected.

00:37:42.000 --> 00:37:52.000
Then we can try to explain such balances Dark Matter density very honest Demetri and so on. By introducing for example, new specialist of neutrinos many models.

00:37:52.000 --> 00:38:10.000
These neutrinos are very heavy, they can be light heavy right handed and so on. In many of these scenarios. This neutrinos are heavy and, moreover in many of these as extensions of the son of model, then you train us or weekly coupled to the standard

00:38:10.000 --> 00:38:13.000
model, and then they are along with.

00:38:13.000 --> 00:38:28.000
However, in my presentation. I want to focus on from the case of the heavy neutral leptons. So if you want to get to know more about heavy long Cliff neutrinos you have to go to other presentations, but still I think that my presentation can be interesting

00:38:28.000 --> 00:38:36.000
for the audience, even if I, if I, I focus on, on, on the shortlist neutrinos.

00:38:36.000 --> 00:38:50.000
So the question is how to introduce the heavy neutrinos disturb model. Well, the easiest way is to add some terms to the Standard Model Lagrangian first one can add the term corresponding to the heavy nutrient propagator and then some terms corresponding

00:38:50.000 --> 00:38:52.000
to new interactions.

00:38:52.000 --> 00:38:56.000
In our case we have three new vertices.

00:38:56.000 --> 00:39:11.000
We have interactions with w exhibit and Higgs bosons, and this kind of a scenario is is a minimal scenario, we don't have any additional gauge bosoms we just have certain model bosons and extra neutrinos.

00:39:11.000 --> 00:39:25.000
Of course, one has to implement certain model to do any analysis. And then we use the heavy and model, it's a newer model implemented within the assign roles.

00:39:25.000 --> 00:39:39.000
It's a kind of an effective extension of the standard model, and the toast of this model was done because the model was widely analyzed researchers have Hadron Collider so you can find many different papers on this topic in the model there are three new

00:39:39.000 --> 00:39:55.000
having a trainers, they can be both Myron or direct protocols and they are the noted as an one and two and then free in their model there are 12 different free parameters First we have three masters of these three new neutrinos and his master's can be

00:39:55.000 --> 00:40:04.000
set in the ranch from hundreds of gv up to a few thousands of G, and.

00:40:04.000 --> 00:40:17.000
And there are also nine mixing parameters which are just elements of of free by three matrix between the Standard Model leptons and this heavy neutrinos.

00:40:17.000 --> 00:40:22.000
Of course, the question is, where we can search for such neutrinos.

00:40:22.000 --> 00:40:36.000
Because if we want to search for these particles, if we want to observe from the case of the case of such particles into some standard model particles, then an important thing to do is to reduce background and possible background contributions to our

00:40:36.000 --> 00:40:39.000
analysis.

00:40:39.000 --> 00:40:59.000
One way to do so is to use filter in policy manuals colliders as the ones listed here. So currently the four different proposals of n plus minus machine FCC and CPC, which are very similar providers and IOC and League, which are linear colliders, and

00:40:59.000 --> 00:41:17.000
in this presentation I want to focus on IOC and league because cleaner colliders offer higher energies and if we want to search for a really heavy particles, then we just need high energies, to be able to produce this particles.

00:41:17.000 --> 00:41:36.000
Let me say a few words about each of these proposals. So first IOC it's a collider to be built in Japan, and into the US superconducting accelerating cavities to accelerate electrons and positrons length of this product is assumed to be 31 kilometers,

00:41:36.000 --> 00:41:45.000
and to do the offer energy starting from 250 GV up to 500 dv. Also there are some considerations concerning the as the pole.

00:41:45.000 --> 00:41:54.000
And also there is a possible upgrade up to one TV and excellent feature of this machine is that both beams.

00:41:54.000 --> 00:42:13.000
is equal be polarized at the level of 80% for electrons and 30% for positrons comma cleaner collider is another preposition to be built at CERN, and to do the US and other accelerating scheme and novel scheme of of using two different beings first dr

00:42:13.000 --> 00:42:19.000
beams, providing the radio frequency power to accelerate main beams.

00:42:19.000 --> 00:42:20.000
And then it would be able to achieve energies, up to free TV.

00:42:20.000 --> 00:42:39.000
And then it would be able to achieve energies, up to free TV, but they're free different energy status as soon as soon for this proposal, starting from 380 GV 1.5 TV up to up to three TV, and that clip only electron beam would be polarized at the level

00:42:39.000 --> 00:42:42.000
of 80%.

00:42:42.000 --> 00:42:50.000
Okay. In our analysis we focus on the single having adrenal production, and to search for this process.

00:42:50.000 --> 00:43:07.000
We can use many different ways. They're both direct ways, when we start for some drama signatures for example Kiki a new continue in your new, and also some indirect methods like electroweak precision observable he's branching gracious and also if the

00:43:07.000 --> 00:43:13.000
neutrinos are long Cliff disposable versus as possible as well.

00:43:13.000 --> 00:43:30.000
In, in this case we probe the signature of quirks and quirks leptin and and Nutri now, because it allows through direct reconstruction of the heavy neutrino if we are able to measure to death, and the left and then we can say something about mass of the,

00:43:30.000 --> 00:43:51.000
of the heavy neutrino in our setup we considered both direct and majorana neutrinos but in this presentation I want to focus on on the direct pace, and one masters were set to from 200 DV up to 3.2 TV and masters of end to end and free particles were

00:43:51.000 --> 00:44:07.000
to 10 TV, all the contents of an one were said to the same value and the value of point or free was used for the generation of reference signal samples. But in general, this parameter was every parameter of our analysis and older and two and then three

00:44:07.000 --> 00:44:15.000
And then two and then three couplings were set to zero. So in other words we have only one having a trainer in the game.

00:44:15.000 --> 00:44:18.000
We considered three different collider scenarios.

00:44:18.000 --> 00:44:35.000
But I want to focus on is the 500 DV with an integrated luminosity a fine phone 16 of us up to bonds and and polarization of minus 80% for electrons and plus 40% for positions.

00:44:35.000 --> 00:44:48.000
Here you can see a cross section for for for for our signal process for different collectors setups for left right polarization including spectra.

00:44:48.000 --> 00:45:00.000
Important thing to observe here is that the cross section is almost uniform, up to the energy threshold is of the order of 10 fun to bond. for each provider.

00:45:00.000 --> 00:45:06.000
And then in decreases very fast up below attend to the second and so on.

00:45:06.000 --> 00:45:24.000
Of course, it is not a kind of background three analysis, because in the standard model we have many processes which are, which are in fact background for these kind of searches and to also the same process can be mitigated with flight neutrinos right

00:45:24.000 --> 00:45:51.000
we have exactly the same diagrams. When we replace the having a three now that we've liked one. And then, and then we have an example of background process. The first there are so many different processes which can can can contribute to this analysis.

00:45:51.000 --> 00:46:07.000
first we generated, our signal. Again, a blessing man was going to a light having to train up for and then having a community tank into quirks and the laptop, and he saw a signal and the background so all the processes, without and proper gators without

00:46:07.000 --> 00:46:14.000
having you Trina and in the analysis, we also included a gamma, gamma gamma background channels.

00:46:14.000 --> 00:46:26.000
Then we simulated detector response with Dell fest. It's the first simulation framework which allows to parameter is our detector acceptance. And in the next steps we pre select.

00:46:26.000 --> 00:46:38.000
We selected even some matching that required signal topology in this case we wanted to have exactly one heavy neutrino so to get the signature.

00:46:38.000 --> 00:46:43.000
We searched for the events, with two dots and one laptop, and that's all.

00:46:43.000 --> 00:46:51.000
And then we use machine learning can CLS to get our final results.

00:46:51.000 --> 00:46:57.000
So please look here at this lot of the key GL invariant mass after the press selection.

00:46:57.000 --> 00:47:15.000
Stage. So you can observe three different careers for E background, gamma, gamma, gamma background and also for our signal is a kind of a different scenario, we've mastered the having your train of 300 dv.

00:47:15.000 --> 00:47:33.000
300 DV which corresponds to the mass of the heavy neutrino, of course, the signal is below the background theory, so it's not perfect, but still you can see that this this variable is really powerful in in discriminating between background and signal

00:47:33.000 --> 00:47:49.000
samples. 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.

00:47:49.000 --> 00:48:05.000
It was done for for again for the same scenario with with having neutrino with mass of the of 300 dv. And to me, owning the final state because at this level we treated separately, electrons and nuance in the final state.

00:48:05.000 --> 00:48:15.000
And as you can observe the distributions are not separated, but still you can see that, that there is a kind of separation between these two distributions.

00:48:15.000 --> 00:48:30.000
Then we we implemented the CLS using the BD response distribution to build a model within your stats. And then, we were able to combine tunnels and also implement normalization uncertainties.

00:48:30.000 --> 00:48:42.000
Here you can see steel results for electrons and healing separately. This our limits on the cross section for the, for our signal process as a function of mass of the heavy Trina.

00:48:42.000 --> 00:48:54.000
You can see that the results for for nuance are slightly better because these are exclusion limits. So we want to have them as low as possible. So, yes so results from your answer or slightly better but.

00:48:54.000 --> 00:49:02.000
But in any case, the results are of the order of one or one sample box.

00:49:02.000 --> 00:49:18.000
Then we translated our results in into a plot which is a bit more convincing I believe. Here you can see limits on the VLN squirt it's our mixing parameter.

00:49:18.000 --> 00:49:25.000
Compare like for results from our analysis and for different from different analyzers.

00:49:25.000 --> 00:49:41.000
So first you can see results for iOS, the 500 DV is the one TV and the peak free TV, compared to results coming from the CMS this apparently limits coming from the real experiments, and this are predicted results for high low latency, high energy latency

00:49:41.000 --> 00:49:55.000
and SCCA take, you can see that results for for the electron positron collectors, or by orders of magnitude, and more stringent than those obtained at 100 machines.

00:49:55.000 --> 00:50:11.000
One important thing here is that in this analysis with this free pattern machines that there was a kind of different assumption because they excluded from the analysis so they get slightly better results because of this fact in our analysis we still have

00:50:11.000 --> 00:50:20.000
still have doubts. If we exclude house from the analysis we will have even more stringent results than those presented here.

00:50:20.000 --> 00:50:38.000
And the last question in my presentation is, if the neutrinos are really short for you. So in our case or the lowest masses considered in this study, again it was at the order of hundreds of dv deli meats obtained in this analysis correspond to waves

00:50:38.000 --> 00:50:57.000
of the heavy neutrino at the level of a few killer electron volts and then see tau is below one nanometre So in any case, we are not able to observe any displays vertices, for example, because then you train us from the experimental point of view, really

00:50:57.000 --> 00:51:16.000
shortly. Of course, one important thing is here is that, in principle, we can search for for long leaf neutrinos in in this kind of model, but then the masses of subtle political should be below, or a derivative of mass of the, of the dub, it brings me

00:51:16.000 --> 00:51:19.000
to my conclusions.

00:51:19.000 --> 00:51:35.000
And I hope I convinced you that that future blessing Magnus colliders who would be able to to search for having a Trina's in a direct way, and then neutrinos could be observed almost up to almost up to the kinematic limit.

00:51:35.000 --> 00:51:49.000
And the results are much stronger than those that tallied See, or if any other hadn't machines, and to our analysis was already accepted for DJ happened to be published, third person.

00:51:49.000 --> 00:51:55.000
Thank you very much for your attention.

00:51:55.000 --> 00:52:00.000
You think you're in charge of them.

00:52:00.000 --> 00:52:05.000
Okay, thank you very much. that was 15 minutes, shy.

00:52:05.000 --> 00:52:09.000
So let's see if there are any questions.

00:52:09.000 --> 00:52:19.000
If not, I will start by asking you a question related to the block you Sean slide 16.

00:52:19.000 --> 00:52:20.000
So of course.

00:52:20.000 --> 00:52:27.000
Okay, this is the money block essentially now.

00:52:27.000 --> 00:52:37.000
Like, how do you think, how did you take these lines for the Elysee, like for example I, I heard you mentioned the fact about the town.

00:52:37.000 --> 00:52:45.000
Could you elaborate on that and and yes please is the CMS line.

00:52:45.000 --> 00:52:59.000
Yeah. Okay, CMS line comes from the data so it's it's a kind of an extraction.

00:52:59.000 --> 00:53:01.000
But that's the solid line.

00:53:01.000 --> 00:53:14.000
This one, these are the entire line. Okay. Yes, this one and this reliance came from this paper. So, it was the same analysis, the same type of analysis but for Hadron Collider.

00:53:14.000 --> 00:53:28.000
So, the results are just extracted from this analysis and it was done for this basically the same model, but with this assumption that they don't have power in their analysis because in that case, they have only two non zero Catholics, to have on the

00:53:28.000 --> 00:53:40.000
than humans, in our case we have all that for the freelance. And, of course, because Taos can escape the vector by device, then our results are slightly worse.

00:53:40.000 --> 00:54:00.000
Then, but then the natural question is, what would your life look like okay better but yeah better by an order of magnitude or, 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

00:54:00.000 --> 00:54:09.000
our results because then you just have to rerun the whole analysis, because it's slightly different for example for lower masses when you have children.

00:54:09.000 --> 00:54:19.000
You have to do the whole thing. Yeah. And for very high masses like to. Ok, ok, ok, but then this part is, if you want dangerous for you because it could be better.

00:54:19.000 --> 00:54:21.000
It's like a pessimistic.

00:54:21.000 --> 00:54:40.000
Okay, think yes yes but I also see that she has a question we have time for that. Yes, we just do this as we are in the cockpit of the lung new particles, here are to a lot of power need to be it is about these old can we improve your your your own sensitivity

00:54:40.000 --> 00:54:50.000
with this new product signature that displays Where does your, your this week's angle going to tend to monitor seven.

00:54:50.000 --> 00:55:05.000
Yes. So in principle you could go to long diff verticals, but then your coupling would be so low level that probably you would produce like a few having a Trina's.

00:55:05.000 --> 00:55:24.000
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 for example displays the vertices analysis for for well for very low couplings and for very high masses, because

00:55:24.000 --> 00:55:30.000
you just have to low particles is 32 few particles to observe something.

00:55:30.000 --> 00:55:38.000
Okay. We saw we have to gather here because the time is already quite late on the schedule, we can follow up a matter most anyway.

00:55:38.000 --> 00:55:45.000
Anyway, she knows your turn. Thank you very much for your for your talk Khrushchev.

00:55:45.000 --> 00:55:46.000
Okay, so keep being.

00:55:46.000 --> 00:55:51.000
We can see you. Can you share your slides pre, please.

00:55:51.000 --> 00:56:04.000
I can say, one second it's loading for me. Yes. Can you try it try to change them particle, the next oh yes that's perfect. Okay, so you were talking about h&s searches at the economic Collider.

00:56:04.000 --> 00:56:06.000
Okay, thank you very much. Please go ahead.

00:56:06.000 --> 00:56:21.000
Thank you Thank you will go either policy meditation, and retro pay or fast to play dinner without here, and this work is done with a few colleagues, up to like plan but high on and how hon.

00:56:21.000 --> 00:56:28.000
And also so R rated heart attack or she now is the faculty in HR I India.

00:56:28.000 --> 00:56:44.000
So we have some middle class white papers to few months, two months ago, roughly, and they work, the wheel papers. Dream summer more official work they come very soon, Hopefully this month.

00:56:44.000 --> 00:56:59.000
So just give us a very simple introduction and motivation. Since the USA, electron, I'm Kreider Are you the pool of the, and it definitely will be built in Brookhaven National Lab.

00:56:59.000 --> 00:57:20.000
This highly cost Kreider rr, we can we need to take advantage of this credit to explore, as much as we can, of course, is a min Menifee charts, I just need some of them like polarized electron beam and the new, new clumpy, including most of the proton

00:57:20.000 --> 00:57:25.000
beam, and it can also extend to heavy iron.

00:57:25.000 --> 00:57:47.000
That is a limb indicated, so we can have the you also from this to determine, or even a heavy iron, like a unit or need the center of mass energy, not very high up to two optimistically 240 GYH, a part of the biggest advantage for this crater is high

00:57:47.000 --> 00:58:04.000
luminosity compared to the existing, and you'd have to come. The dis machine Nika here are you can reach is the factor of 10 of that, up to 31,000 times, compared to exist in luminosity.

00:58:04.000 --> 00:58:15.000
So of course the goal for us is money for God as up to Zd machine into a problem with their problems plane and all this park blue container or product, or even you have IR.

00:58:15.000 --> 00:58:34.000
However, we should also take advantage of this machine to think about the other physics right he left him with precision physics, or even bsm. So, I give a nice list, or even a very big white through my slide papers here, which is the layout.

00:58:34.000 --> 00:58:40.000
On Monday possibilities there, and our standard long have a white paper.

00:58:40.000 --> 00:58:58.000
Long study will serve as one of the case study in this direction. So we take this I have a new laptop, as an example.

00:58:58.000 --> 00:59:18.000
Under the electron machine, and then CNC machine energy with our Medicaid can up to 140 t waves, so you know from being Palumbi I listed here. The integrated Illuminati, I just, just so you can be up to 100 immersed in the bar under the detectors, the

00:59:18.000 --> 00:59:21.000
conspiracy it's like this.

00:59:21.000 --> 00:59:40.000
you have a problem come from one direction and the Euro from from another direction in under the basic setup like the tracking system, the column meter, and also the ongoing comical coverage, or you just do some basic because up to 3.5 in the board they're

00:59:40.000 --> 00:59:45.000
actually in, so which is kind of impressive.

00:59:45.000 --> 00:59:49.000
So this is a basic level we take the end of our inputs.

00:59:49.000 --> 01:00:10.000
So let's look at our. So what we can do with basic this machine. So we do we take this to have a neutral neutral models. So I just know right out this this basic diagram, under the corresponding interaction with a standard model, mostly from this KGE,

01:00:10.000 --> 01:00:32.000
the bottom Wz under the cross section here compared to this a normalized two days two weeks ago, it can reach you to kind of 38 Peak bar or so. So when we're talking to consider about this new this new browser here, to which you lawfully come to 100 immersed

01:00:32.000 --> 01:00:39.000
in the bar so the events that we continually Miss mix and go to be unit unit.

01:00:39.000 --> 01:00:43.000
The events can be up to one meetings events.

01:00:43.000 --> 01:01:02.000
So, so that's a significant advantage compared to the existing team in in machine, or even to these inherent like this. So when we folded into this, consider about this week's mango, so we come up wanting to produce these habits, a neutral Adam, up to

01:01:02.000 --> 01:01:17.000
order one, or 10, events, it can be reached to the sensitivity to this mixpanel tongue to tend to minus six. That's the goal. That's our hope to explore that with this machine.

01:01:17.000 --> 01:01:39.000
In, so So let's see how far we can go, that's nice about this, to kinda go to scenario to kind of a particular region. Why is the kind of high mass higher mass was smaller or was Niger mixed angle in this region we will alter this one is mostly in the

01:01:39.000 --> 01:02:01.000
new the fall for this is a promoted the case arch. So I need to view the signature channel type we can have will charge you to sleep with a few heavy jets under also we can also have all this a charger brimstone with also flavors changes channel actually

01:02:01.000 --> 01:02:18.000
new channel, which is also a very unique thing each our from our I have a new product on part of what you don't have a laptop, so we can, we don't have some unique sound so we have just a normal thing reach our life and you know Tom plastic that's left

01:02:18.000 --> 01:02:39.000
on plus or minus. The coverage you are the combinations. So, so Oh Father Marana with the next one, Sam. I with together is three type of Jed, we have all the bondage to we will double or the final stage, so we can become stronger This is the heavy leptons

01:02:39.000 --> 01:02:46.000
on the margin moss such, so so for example we can take this.

01:02:46.000 --> 01:03:08.000
The 10 GV of heaven, and we can talk with the heavy let this emerging master based on this one you can say, they come down to this one.

01:03:08.000 --> 01:03:19.000
Martin gv this so unique sending each other we continue to add to, to isolate or to surprise the brick wall and outer balls simplify this, the signal.

01:03:19.000 --> 01:03:26.000
So let's try to focus on this, this signal chart first.

01:03:26.000 --> 01:03:32.000
So, so this is a signature this can give a stronger signal.

01:03:32.000 --> 01:03:51.000
And we have also perform they sell all their phone call configuration details for simulation, and we have optimized these, the car chromatic car to send to to you or to magnify the signal surprise a brick wall, and these two of them, and then the call

01:03:51.000 --> 01:03:59.000
flow table here under the biggest background, coming from this misidentification of the next one.

01:03:59.000 --> 01:04:15.000
And because of the notch events coming from these just to the dis scanner which it doesn't miss identify one electron with your sleep Sam. I always put a fake the fake though, for instance, so.

01:04:15.000 --> 01:04:35.000
So reach out to optimize this business card flow and under them. Then, then we found listen to the master window, this is I mentioned that the murder master cartel can logically have any suppressed this background, and we take advantage of this one.

01:04:35.000 --> 01:04:51.000
Under the currently existing in, in most of precisely Me, me, me said, I didn't take any of it that's all beside me You can be up to a point 1%. So, so this is the existing can, we can pay to park in the future.

01:04:51.000 --> 01:05:03.000
That's the projection some $1 bill need improvement in the future so we can give him the opportunity to better serve our banner sensitivity and that's the thing this is the one we can't get.

01:05:03.000 --> 01:05:20.000
So, so you can say this.

01:05:20.000 --> 01:05:39.000
based on this, this simulation, we can at large he murdered my lucky, have an outcome last, I could tell other tends to become rich you can do this mix tangled up to come to minus three, sometimes can be you boy can improve all this misidentified me rate,

01:05:39.000 --> 01:05:54.000
because even Richard tend to minus four.

01:05:54.000 --> 01:06:10.000
For this one, and with his unique thinking which are part of our body, father. However, we have a significant big one coming from this town hall decay, which he was respected to prevent this way all the Bluetooth, this, this signal.

01:06:10.000 --> 01:06:33.000
So, so the will to come. As a result of this channel, give us the comparable. Since a team of teams in under others directs the signal so we have we don't have a unique Cindy charter we just to form this, the laptop pairs, without the synergies one Jerry

01:06:33.000 --> 01:06:44.000
transmission energy. The under we gotta keep some sensitivities, which want to give us the same same narcissist sensitivity coming into the mix angle with the demonic type.

01:06:44.000 --> 01:06:48.000
So that's the main message from this promote decay.

01:06:48.000 --> 01:06:54.000
Hey, since we are talking about it is not only part of your four minutes to go. Okay.

01:06:54.000 --> 01:07:07.000
But we're talking about Islam evil signature landing particles, you thought greed out of our nature for us to take this chart to identify this is heavy leptons under the finance a lot of devils the particles.

01:07:07.000 --> 01:07:27.000
So we, such as the Oneness so you might have a masa masa could be small, under this mix number to be small region. This is the lower corner. This one will correspond exactly to this, that not only was a particle signature under the tears, we show this,

01:07:27.000 --> 01:07:43.000
the dependency concurrency up to the detector side.

01:07:43.000 --> 01:08:01.000
signature and can say this the DMS on will be mass on the case that's under. Oh, no lovely will part of your signature so for this give you five TV have an Epiphone cumbia which is to significantly inside of the car but others which TV sunbelt background

01:08:01.000 --> 01:08:02.000
can be suppressed.

01:08:02.000 --> 01:08:07.000
So, so we have a little performing this is a vendor selection.

01:08:07.000 --> 01:08:11.000
Some typical event tracking, and we can attain that in this.

01:08:11.000 --> 01:08:26.000
Some typical trans trans of ours impacts back in patch that starts on the perform the floor simulation of their detector size or configuration, sending size, and the, we have get an insistence activity.

01:08:26.000 --> 01:08:43.000
If you listen only of Sydney charging kind of same. This is an improper the low mass under no environment mark, no no mix mango said so regions, which is the one to 1010 GV, another the mix of all come down to fundamentals six.

01:08:43.000 --> 01:08:56.000
So we give another set top under competitor existing in in starchy especially if I'm common system as we can cover some loose, new parameter space. So, so, so this let's summarize.

01:08:56.000 --> 01:09:11.000
Yeah, this is a DVD, both wrong this promoted K, and this displays, promoting decay we can probably sensitivity it's comparable compared to your skin for the larger environment.

01:09:11.000 --> 01:09:25.000
Not you have another master under lovely hires mix angle, you know, no, no, no, no, no me Sangha, we can use the denominator signature to probably give her space regime.

01:09:25.000 --> 01:09:28.000
Then, so, so that's our moment applause.

01:09:28.000 --> 01:09:44.000
So, last one we just to move just to just to one, and we'll start from the this everybody K, because they haven't let them come decay into some mix nice in a missing part, but let's talk about ourselves.

01:09:44.000 --> 01:09:55.000
So this is just in Richardson whiskey shoe I'll be at ESA at the moment yet. We also saw considerable this signature to come to say this whole lot you we are sensitive to go.

01:09:55.000 --> 01:10:09.000
So, this one we found a lot and it depends on the system the system indicates how far, how bad or we can go. So you will consider about and this is zero system because we can come get a comparable sensitivity based on this signal.

01:10:09.000 --> 01:10:11.000
But if we can have can not will come out of this system had success and 71% 1%.

01:10:11.000 --> 01:10:21.000
will come out of this system and success is 71% or 1%. We lose sensitivity based on this channel.

01:10:21.000 --> 01:10:37.000
So let me conclude, but he has said he will open up a new cruise at frontier, but we also need to consider about the bsm starchy. So we take them there Yeah, there's nothing new about having to show that was a model to pop up with a disregard have so

01:10:37.000 --> 01:10:55.000
we can cover some new parameters face with a few gv will ask you in a bottle for the promise Archie we can, and also to get a comparable The, the problem compared to the existing term chimps, so So with this study I will inform us about the future, it

01:10:55.000 --> 01:11:06.000
is a determinant design especially part of this tracking system for for this displacements have, of course, there's so many other possibility to pop water which I need to the this reference here.

01:11:06.000 --> 01:11:11.000
So, so let me just stop here and take question.

01:11:11.000 --> 01:11:18.000
This is brilliant 15 minutes and 02 seconds. So questions anybody.

01:11:18.000 --> 01:11:37.000
I have one question actually do. So can you go to slide the criteria is fine for example.

01:11:37.000 --> 01:11:54.000
to reduce the background, and also have you considered cabling to the towers because surely here. You're competitive but face base is very crowded. But if you move to the cabling to the towers, then that's not the case

01:11:54.000 --> 01:12:02.000
for the carbon into the tall You mean this is a heavy laptop, big company with Tao all. Yeah, exactly.

01:12:02.000 --> 01:12:15.000
Okay for the odd one, we, we have do some preliminary study but we didn't found the advantages compared to the existing searches so so we didn't emphasize that direction.

01:12:15.000 --> 01:12:26.000
In your another word to say that there's no advantage to province our perimeter is with this machine.

01:12:26.000 --> 01:12:27.000
Sorry, can you repeat the last part.

01:12:27.000 --> 01:12:34.000
I mean, in for this is, of course, it says yes he left one electron.

01:12:34.000 --> 01:12:52.000
Well, since it's to initialize. So it's a very sensitive to electron flavor and so that's why we've built some this electron capitalism you have a laptop on for others a chance. But I can you mention this couple of tall, though, Devon India these components,

01:12:52.000 --> 01:13:09.000
can provide us on poor, but there is no advantage compared to the existing gene machine to pop can actually say can provide a human or human is AZ is some others Kreider comparable stronger problem compared to this yesterday.

01:13:09.000 --> 01:13:11.000
Thank you.

01:13:11.000 --> 01:13:17.000
I see maybe they take the question from European. This is not a convener your employees.

01:13:17.000 --> 01:13:26.000
Your again please. Your again, breaking out here.

01:13:26.000 --> 01:13:29.000
I see your earlier to our.

01:13:29.000 --> 01:13:33.000
Thank you. A question from on but then yes, you can be heard.

01:13:33.000 --> 01:13:47.000
Good. Two quick questions but, in fact, the handle diverse femme to bond is for how many years of running. I, I'm, I need to check it so wildly five to 10 years, five to 10 years.

01:13:47.000 --> 01:14:08.000
Okay. And the plotters we have it here on figures, then it doesn't actually say which they die your show that is already showing excluded reasons this the recent data from the collider I think they they go to lower couplings at the low masses, and then

01:14:08.000 --> 01:14:11.000
what seems to be excluded here.

01:14:11.000 --> 01:14:24.000
We have included though they exist in starchy and I call this a. The reason to exist in starchy but under the core the project the one can go below.

01:14:24.000 --> 01:14:36.000
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.

01:14:36.000 --> 01:14:39.000
So maybe you check once.

01:14:39.000 --> 01:14:53.000
If it's really up to date, just just for the sake of getting questions somewhere on a conference for example, yeah yeah yeah we have the most of one the updated one coming from CMS.

01:14:53.000 --> 01:14:54.000
Okay.

01:14:54.000 --> 01:14:59.000
But it's not it goes too far compared to the subplot. Okay.

01:14:59.000 --> 01:15:14.000
Okay, thank you very much I think we can take the question from European okay just very quick and now you can hear me right yes okay right well yeah so can you can you say a few words about the status of the Standard Model predictions for the electron

01:15:14.000 --> 01:15:30.000
ion collider so what is 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 get an estimate on the or a prediction on the Standard

01:15:30.000 --> 01:15:35.000
Model backgrounds for these processes.

01:15:35.000 --> 01:15:40.000
standard the mode of background for this process.

01:15:40.000 --> 01:15:53.000
So, we have a use this up to left meeting water or some costly we can we can we can improve after that next meeting. What are the data that one.

01:15:53.000 --> 01:16:07.000
We are not changing our conclusion based on the Society for others processes definitely maybe we, we, I'm not sure how Hulu.

01:16:07.000 --> 01:16:19.000
Like DD is the measurement because of the, yes. Most of the procedure machine for co CD started definitely that we need to that one but not a full bsm search.

01:16:19.000 --> 01:16:22.000
Okay, thank you.

01:16:22.000 --> 01:16:25.000
Thank you very much. Thank you for the dog.

01:16:25.000 --> 01:16:28.000
No more to

01:16:28.000 --> 01:16:44.000
it.

01:16:44.000 --> 01:16:50.000
It's not full screen yet. No, it is

01:16:50.000 --> 01:16:56.000
my microphones on so now you're muted Yes.

01:16:56.000 --> 01:17:17.000
Alright, so this last contribution of this session is different kind of paper than the ones we discussed before. In this session, this is on the white paper, which was, as you will see commissions in in this No Man's effort, and it's about the present

01:17:17.000 --> 01:17:29.000
and future status of heavy neutral leptons so it's a kind of a summary from what whatever we got the information from and so maybe some Charles you're not aware of that as it may be interested.

01:17:29.000 --> 01:17:37.000
Interesting. And then these are the actors, which you see here that I've worked on this paper and signed it.

01:17:37.000 --> 01:17:55.000
Okay, so as sets was commissioned by the neutrino physics frontier group, and it was done in concert with the energy frontier, and the rap process from the at least was communication and getting things done and I'm not sure we got all the information

01:17:55.000 --> 01:18:15.000
but we got quite a bit. And the overall editors for myself and Ian Schumacher, and you'll see all the characters for the different sections we have in that paper from theory collide The Searchers more be dedicated or nuclear as it became a new chapter,

01:18:15.000 --> 01:18:23.000
fixed dog with experiments or expected beams if you want, atmospherics solar data, and also from cosmological bounds.

01:18:23.000 --> 01:18:42.000
And this is the archive where you can find that, where the first version is on, and the revised version or with with input we get. We will still submit when when things calm down and all the input we get in detail, not to be looked at source there that

01:18:42.000 --> 01:19:01.000
may be right now but you can see this is the contents of the paper it's about 70 pages or so with the theory motivation introduction and some visions there on what they wish for the future to see collider searches takes a large chunk in that nuclear decay

01:19:01.000 --> 01:19:14.000
searches or nuclear processes so it's a smaller fraction than the extracted beams, with a whole lot of process projects going through. And then the other chapters which I will go up to now the the content of the baby is a snapshot at the status of the

01:19:14.000 --> 01:19:24.000
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, February.

01:19:24.000 --> 01:19:44.000
Earlier this year. So for example, the latest results of Atlas which came, you know, a month or two months later, or not at this present at the present time included there but that it's more broad on prospects anyway that we're trying to do.

01:19:44.000 --> 01:19:52.000
From the theory, I will not say too much, Mark was supposed to be around but it couldn't be couldn't volunteering for the top here so.

01:19:52.000 --> 01:20:05.000
But I will not go into much of effort in here just saying one interesting blogs which you may see time and over again coming time Swinburne is having to let us have discussed.

01:20:05.000 --> 01:20:24.000
And that is the connection with the Standard Model adrenal 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 H and nails in order to have for example agent has to be

01:20:24.000 --> 01:20:40.000
reasonable explanation for the fact that these active materials have masses. And right now if you look at the bottom in the space of the oscillations for the active neutrinos you map that down this ternary diagram which is showing the couplings to the

01:20:40.000 --> 01:20:57.000
difference Venus of the heavy neutrinos to the light, not like the train of this side normalized to the sum of all the goblins to this neutrino so that's why they run sort of like rancher band one and between zero or above zero, then these are the regions,

01:20:57.000 --> 01:21:10.000
which are allowed, right now, depending also if you have a normal ordering or an inverted ordering into the three nutcase mean you heard about that yesterday about this question that we don't know.

01:21:10.000 --> 01:21:25.000
Exact ordering of the three the three the masses, as we have this as it is today but interesting if you see if you get too into June in the future, then these regions, because of the better knowledge of this isolation pardon me, this will be actually

01:21:25.000 --> 01:21:44.000
coming into this kind of ellipses you see here, which would be allowed for so the face space for the HTML parameters would be very constrained so if we want to start measuring it you can actually see if you observe this right handed the three knows if

01:21:44.000 --> 01:22:01.000
they are actually in sync with with with with explaining what is happening in the sector so far, know that this is for a simplest model effort to active states and so forth, but it's a start that shows you that there is this intimate connection which

01:22:01.000 --> 01:22:05.000
is not necessarily to be forgot.

01:22:05.000 --> 01:22:14.000
By the way, in the theory bar they're stressing particularly also that we should go beyond the non minimal models. So we'll show for future.

01:22:14.000 --> 01:22:30.000
And, which would include that we take one more active flavor at the time now we take just single like the flavors in the HTML to benchmark points, but on the benchmark points itself, there was not much there is not much discussion despair, that's referred

01:22:30.000 --> 01:22:47.000
to discussions which happened in the physics beyond the collider studies or the Phipps forum which I will show a little bit later, where in fact the theorist and and the experience of working together to get more benchmark points to fight for the Goliath

01:22:47.000 --> 01:23:07.000
I'm almost 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 during this meeting in any case of projections for, for example, the LSC or for all the experiments which

01:23:07.000 --> 01:23:25.000
which are being told off as possible exit experiments to cover more of the face space, and that's that's well known to us so I don't need to preach the choir scheme that one thing I did observe file we made this that's for the high luminous the LLC for

01:23:25.000 --> 01:23:40.000
examples there are not really prospects, made by atlases CMS or eligible for that matter, as you have on many other bsm scenario studies that from the knowledge we have.

01:23:40.000 --> 01:23:58.000
Presently, we extrapolate that to the high luminosity with all the assumptions required that for for HTML so we actually didn't have that the only results are found or film illogical studies which is well, good to give you a hint where you're going, but

01:23:58.000 --> 01:24:08.000
that's maybe you we would like to do something better on that in the experiments, that's a colon the experiments, think about that and maybe that's the thing once we have the older run to analysis completed.

01:24:08.000 --> 01:24:10.000
Think about that.

01:24:10.000 --> 01:24:25.000
You may remember in the HTML group we had also ongoing developments on Generate from the agent else for the from the original discussion group, which we have reported in these meetings and some sub meetings we had, and particularly work with Phil and

01:24:25.000 --> 01:24:40.000
is involved in that. We have included the state as it is, what is available in the document as well so this is not yet the final word then you're still development that further, but at least people see what's there and what what what are possible things

01:24:40.000 --> 01:24:43.000
to come.

01:24:43.000 --> 01:25:04.000
Now, for the extracted beings. There are a number of the prospects for projects disgusts like the ones we know well like any 62, but also in ship for example, but also the new proposal CERN which was presented last laptop, the longest particle meeting

01:25:04.000 --> 01:25:23.000
we had the number 10, and number of other experiments which not all of you, you may be familiar with most are in the neutrinos sector but mobile. And then that's now and J bar for example in what they're, you know, possible projections are for sensitivities

01:25:23.000 --> 01:25:30.000
they can reach and they have been thinking of working about that. I give one explicit example here this is for June.

01:25:30.000 --> 01:25:41.000
And this is what is now the official sensitivities of June, they haven't hadn't been done really within June, but there were phenom illogical studies for that.

01:25:41.000 --> 01:25:46.000
And now this has been done for. and within the collaboration.

01:25:46.000 --> 01:26:02.000
I will not go into the details you can find it back in the paper here but that is for the most recent configurations of the near detectors which we have for the problems of targets profile, which we expect, which is the six plus six years thing which

01:26:02.000 --> 01:26:18.000
means is six years old, the starting intensity of the beam and then plus six year of the high intensity of the beam, therefore there's different scenarios to set what the different sensitivities are for the agent cells with dominant cobbling to electron

01:26:18.000 --> 01:26:29.000
beyond my style here, or the flavor universal one, but that for example covers. If you want in its totality, up to 12 years of data taking.

01:26:29.000 --> 01:26:50.000
This is an overview of projects where you can compare them for example, you know just the lookup table which is giving you the beam dives you have the detectors distances, the decay volumes distance from the dump problems from targets, and not in the

01:26:50.000 --> 01:27:01.000
least. But definitely time scales, good define scales, as they are today. So if you are interested in a particular regional face babies are so you see this will that experiment coverage.

01:27:01.000 --> 01:27:07.000
This is giving you somewhat more information at one glance of the deals obviously in the text.

01:27:07.000 --> 01:27:26.000
That's particularly for CERN, I just know two things here, there are the future, new experiments we can have no ship is something which has been talked about for the last eight, five to eight years or something, the ads, you saw there was no date, given

01:27:26.000 --> 01:27:45.000
here because for that experiments. That was not thought of favorably encouraged, with the last 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.

01:27:45.000 --> 01:27:56.000
So for that experiment people have been rethinking of a more cost efficient option for building the beam done facility which was the most expensive component in that.

01:27:56.000 --> 01:28:14.000
And there are now ideas, how it could be made more cost efficient and to a large factor which no I shouldn't name yet because it's not not terribly efficient but it's enough to be happening under three discussion with similar is almost identical sensitivity

01:28:14.000 --> 01:28:19.000
us was in the original proposal, but maybe, maybe a bit less.

01:28:19.000 --> 01:28:26.000
Brandon what what one wanted to do what were all the new things want to do to build this experiment.

01:28:26.000 --> 01:28:41.000
And the second one is new project I'm just reminded, there was no specific talk on that in this meeting, but the guy on the phone, she did this gave a presentation at the last meeting over new detector, which would be sitting, or does this actually decay

01:28:41.000 --> 01:28:57.000
volumes spectrum either and the beam comes from this side through it, and it's sitting next to me 62 so it's an off axis experiment, but benefiting from the high rate and problems the target you get connected with, and it's 62.

01:28:57.000 --> 01:29:11.000
That's is at the moment of an expression of interest which has been submitted to the comedy here and is now with the referees and, you know, that's also if we see that may happen if it happens, it's something like 10 years from now, to build an approval

01:29:11.000 --> 01:29:12.000
from finance and so forth.

01:29:12.000 --> 01:29:24.000
and finance and so forth. Now new, which are in this paper are with all these projects and, which I mentioned before for these extracted beams and all the works been done.

01:29:24.000 --> 01:29:39.000
That's the new sensitivity Curse of being given a days are being blots bloods on such plots and you see just as usual the compliment guarantee that is being probed by by June, which is the green line which you see somewhere here maybe not so good on this

01:29:39.000 --> 01:29:56.000
162 ship and shadows for the different theories, you better for example for the different projects, and you see particularly that this neutrino experiments are going to be good below the K on mass death region here and then of course the higher energy

01:29:56.000 --> 01:30:11.000
beams, take over the building was three new experiments typically have only a lowish energy beam on targets one low to ship it it's it's it's probably 100 gV but it's not compared to the 400 GV for example.

01:30:11.000 --> 01:30:25.000
And that's the same for the data 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 information and then let's in the last few minutes, there's something on something else that is searches

01:30:25.000 --> 01:30:44.000
for agent calls regarding the very low mass range which means up to maybe 10 MEV or so and below, starting from the KV level. And then we come into the nucleus of processes, particularly like be dedicate searches were like Catherine is doing now, Catherine

01:30:44.000 --> 01:31:01.000
measures to be done the case back and in fact they're only interested in this part here to find if the like from the tree nine miles or so but in the spectrum itself, that would be a Chanel's you could get the kinks and so well that's something that don't

01:31:01.000 --> 01:31:15.000
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 games, and a particular upgrade of Katrina was called Kristin

01:31:15.000 --> 01:31:35.000
Kristin would be able to measure differentially he and I would have a good sensitivity in that region so that you could search for from such from this games in some interval between few kV till about almost 18 kV which is the the endpoint which I have

01:31:35.000 --> 01:31:51.000
for four H and Nelson, this would be like the trust the Catherine sensitivity itself compared to exclude the bounce already in that region. that would be Tristan upgrade one which would start 2025 or so.

01:31:51.000 --> 01:32:10.000
During can also play a role in here looking at the outcome 39 atoms that are the decaying, and if you don't do anything special for the triggers for that this is where June will sit in the coupling and mouse you go to hire miles because the key value

01:32:10.000 --> 01:32:15.000
of yours more like 850 G 400.

01:32:15.000 --> 01:32:19.000
million, something like 400 KV here.

01:32:19.000 --> 01:32:32.000
And if you do something special on the triggers and the analysis which is of course coming at the price, you could go like two orders of magnitude further down, couplings measuring that.

01:32:32.000 --> 01:32:49.000
And there are a few others that will love your show, I will love few others which I will not go into detail, that is the electric capture which is like the reverse be that the gate process reactor based.

01:32:49.000 --> 01:32:59.000
Verse be the case. And the three nodes be the neutrinos be the wwb the decay also can give information on that. Anyway, these blocks are you in there.

01:32:59.000 --> 01:33:12.000
Then I think the final thing I talk about the natural adrenal flux is coming from either in the three years from the sun, or from the,

01:33:12.000 --> 01:33:29.000
the atmospheric nutrients which we have you have three kinds of mechanisms that can lead you to having agent else either they come directly from the neutrinos in the shower, or you can have such a what they call the double bang events like you can also

01:33:29.000 --> 01:33:51.000
look for 4000 and ice cube that with larger distances and look for for that now using these techniques, and one isn't one isn't up scattering that the three no interacts with, with the nucleus and creates a resident exchange feeling you get the have been

01:33:51.000 --> 01:34:10.000
three in a while. So this is for what Ice Cube could cover from these double banks that they have and 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 under

01:34:10.000 --> 01:34:21.000
certain models, this is not a simple seesaw model but the dual parking constraint model for each analysis to be found to this election you reach a goal for them from solar three knows.

01:34:21.000 --> 01:34:24.000
By analyzing the Barack senior data.

01:34:24.000 --> 01:34:45.000
The final thing without giving too much detail on that on the cosmological and as the physical results is there is an update of that with all the new bounds in here, updated overlaid The Picture Made by Marco with the reaches, which we had before.

01:34:45.000 --> 01:34:57.000
From the different didn't lie there's some soul that's know that this is as good as we know it. Right now, according to our group this which was working on that.

01:34:57.000 --> 01:35:17.000
And since time is over I will not go into the details here at the end this is no mouse paper and gifts recommendations and the recommendations which are all I mean in the in salt of the beholder for what we are thinking certainly that you know HTML and

01:35:17.000 --> 01:35:31.000
long respond to the spikes then further should be a key part of experiments baseline physics program that's particularly goals two to three new experiments which do not have this as a baseline but also Jay was discussing this yesterday.

01:35:31.000 --> 01:35:45.000
Future glider facility should have a star consider requirements for such things, you know we are all working on that. So we we've had it here because this is being used for for this no mas in both.

01:35:45.000 --> 01:35:54.000
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.

01:35:54.000 --> 01:36:09.000
That's for the nuclear experiments which we encourage, and the case of the discovery, which we all would like to anticipate for, we also should think ahead in what actually we all need to measure it, and how are we going to measure it if we are at some

01:36:09.000 --> 01:36:12.000
day so lucky that we actually see a sick.

01:36:12.000 --> 01:36:24.000
That's it's what I want to give us a summary of that just to say that if this is the last day of this workshop and if you're already thinking of to do with your time and would you like to have a new workshop.

01:36:24.000 --> 01:36:31.000
There is a workshop coming up at CERN, which is the fixed 2020 which also mentioned as a benchmark.

01:36:31.000 --> 01:36:45.000
discussion forum wherever that's happening at the moment. And there is for example. So while there are three main topics that have and one is the flavors and their connection to the active adrenal physics so you can have more than that.

01:36:45.000 --> 01:36:49.000
And I'll stop here. Thanks.

01:36:49.000 --> 01:36:59.000
Okay, thank you very much. We are quite ahead on this kit know behind schedule so if there are no questions from the audience.

01:36:59.000 --> 01:37:03.000
I will refrain from asking questions.

01:37:03.000 --> 01:37:16.000
And I think we can conclude this session here. Thank you very much for everybody that participated it's very refreshing to see so much new stuff on a chance.

01:37:16.000 --> 01:37:21.000
So, there is a coffee break now, in theory that should be 15 minutes.

01:37:21.000 --> 01:37:24.000
We let the
