José Zurita: So.
José Zurita: Thank you, whoever started gardening cells that you did you want to share your slides we wait a tiny bit.
José Zurita: Perfect so okay so we're going to start a double session on dark showers since the very first verse of these have been a quite an interesting topic.
José Zurita: And I think he has exploded a lot in the last few years, so, whether as a virtual organizer their worship class actually served to new clay people and in Kobe this huge effort on the show was that.
José Zurita: The availability nicely under snow mask or whether the data was people drawn away from our worship and winter snow Muslim they bloom there.
José Zurita: is of no interest for us what is really interesting that there's a lot of activity that has happened we're going to hear a summary ways to cheat on this is normal White Paper.
José Zurita: And then we will have, of course, a lot of individuals who got hands on action in presenting their own individual papers so without further ado, please, which either go ahead and in about 20 minutes a softer voice of my co host Julian will tell you have five okay.
Suchita Kulkarni: sounds good, I hope you can hear me.
Suchita Kulkarni: Just my screen.
José Zurita: So I see you know perfect.
Suchita Kulkarni: Time or somewhere in check with myself, hopefully, I don't really.
Suchita Kulkarni: Very good um So yes, when i'm asked to present, by the organizers here is a brief summary of.
Suchita Kulkarni: This no malice White Paper on dog showers which is.
Suchita Kulkarni: which was an effort that was running during the lifetime of snow mouse and go briefly about what is come up with what we've been able to understand what we have been able to process them to stop.
Suchita Kulkarni: Okay, very good organization, let me just start with a bit of a background of what this effort was and how it formed, and of course we started with.
Suchita Kulkarni: The most creative logo the logo that will come up with, and as you see the logos and the slide it's very nice logo and it's something that we tend to use when we give the talk.
Suchita Kulkarni: On organizationally we met at least once a month to discuss ongoing, for we have several papers and several nice things that are presented and discussed in the meeting.
Suchita Kulkarni: and have a mailing list, which was, which has a total of about 70 Members now, which basically the monsters, that is a critical mass in this direction and a lot of interest.
Suchita Kulkarni: very lucky and interesting in the group that we ended up with consisted of theorists including my daughter's.
Suchita Kulkarni: Experimental is working on Doc servers and basically this very nice combination of the two enabled across talk among.
Suchita Kulkarni: different groups and had a very cohesive approach also it was a foggy bottom up approach, we never said, people should do this or shouldn't do it is something that we came together, and I think that's something we're very proud of.
Suchita Kulkarni: We have reporting a diverse range of all the meetings i've provided you the link on the slide there is a mailing list, which remains, and if somebody is interested in joining and getting informed, please do feel free to subscribe to the.
Suchita Kulkarni: Medical with this, let me start with the physics part of the job itself, I don't have to basically justify or explain a lot in this audience start.
Suchita Kulkarni: Here strongly interacting new sectors are very interesting because it's one of the places where new fiscal still be hiding identity is one of the places when you feel this construct with any live.
Suchita Kulkarni: Right.
Suchita Kulkarni: By now, we have several reasons, in addition to the fact that there is just a possibility of new physics.
Suchita Kulkarni: And those are partly related to the fact that they give you new unexplored signature, so there is something which we have not looked at, and we should take it.
Suchita Kulkarni: seriously because it's a signature, we could be missing it's related to or it can be related to flavor physics so maybe there is a possibility of.
Suchita Kulkarni: Explaining some anomalies or finding new things in the sector of Labor physics about it, it can be related to new dark matter particles.
Suchita Kulkarni: And that's very interesting possibility as well, since we have not found written article, which is elementary from whatever such as we've been carrying out so far.
Suchita Kulkarni: And finally it's not just that we have new previously unexplored signatures, but the signature spaces, was it has very complex geometry space, and therefore we need to think about it.
Suchita Kulkarni: Rather seriously and carefully about how to map this complex but very interesting period of new physics theories which are stronger interacting.
Suchita Kulkarni: With our residents walk the talk of basically consists of new as you engage groups which are charged under the standard model, the phenomenon, it could be very different if.
Suchita Kulkarni: He will be charged under the standard model, some of the principles remain the same, but what you will come out of as a signature space can be very different.
Suchita Kulkarni: These theories are traditionally characterized by potentially two sets of variables once which are defined in the ultra violet.
Suchita Kulkarni: which are related to the the age group in the dark and the number of flavors in that age group, and if you're the confinement scan longer dark the beach coupling and the Court.
Suchita Kulkarni: And in the ir these translate to basically the masses of the States and the corresponding lifestyle lifetimes and raunchy nationals and, of course, then in between these two sectors, we need to introduce a mediators.
Suchita Kulkarni: So what when gets auto such kind of setup is basically a few different kinds of interesting regimes in in the parameters based one.
Suchita Kulkarni: Fishing where you get doctors were on for a long time since the darkness and the other issue which don't make it so this is a very rough.
Suchita Kulkarni: Classification at this point, but the other regime is where you get soft and clustered energy patterns, also known as OK, and then even in terms of internships can get anything in between these two extremes and I briefly characterized submissions.
Suchita Kulkarni: Now, how i've been dealing with these theories know we've taken our traditionally we've taken a signature based approach, which is another good thing to do when you're starting with approaching, something which we are not familiar with.
Suchita Kulkarni: And what we've done so far in the analogy is to very or parameters of the theory, which is the number of colors or flavors the confinements case the quad mass is the.
Suchita Kulkarni: bounce rate my sister branching ratio says free.
Suchita Kulkarni: In order to collect these theories, the standard model we are primarily two different portals one is the SCI fi portal and the other one is the fundamental teacher portal, so we have external theories and teach other theories.
Suchita Kulkarni: And in terms of signatures business, this way of these have given us 100 signatures in terms of some invisible Jerry too much injured struggling.
Suchita Kulkarni: With not cared much about the bomb states spectrum characteristics, we have built the row and pions on the same footing, for example, and all the simulations that we've done so far are based on pto pto at the model.
Suchita Kulkarni: And this is something that we should be, we should keep in mind that currently there's only one solution that allows us to simulate curious, especially when we're talking about jets.
Suchita Kulkarni: Very good, so i'm the cool.
Suchita Kulkarni: So, for example, Elizabeth details of the of the signatures, what is this me physical jets and the other one is in the emerging jets.
Suchita Kulkarni: In case of semi physical checks, basically, we have a limited edition of.
Suchita Kulkarni: Stable Doc Center particles which are invisible identity and some of the Doc Center particles, which will take you back to the standard model and, therefore, are visible.
Suchita Kulkarni: We assume that all of these particles vicki via to body promptly in the in the detector and therefore you see it as a general contractor.
Suchita Kulkarni: and has been characterized in terms of our invisible, which is basically the ratio of you and Stephen measles measles measles in the right.
Suchita Kulkarni: And, depending on what is the value of this are invisible, you can go from search strategy which is dangerous or socially which are dedicated searches for an intermediate are in or.
Suchita Kulkarni: You might even just on the other hand, are things were taught me some.
Suchita Kulkarni: Time lifetime and therefore going to the category of longer articles, and these have jets with multiple displays my classes, you have.
Suchita Kulkarni: On flavor case, but you only one lifetime your flavors case we have multiple lifetimes for the measles and corresponding to these two of course cms has also look for the searches and have basically come up with the first limits on this planet is.
Suchita Kulkarni: not something we should keep in mind is this signature based approach and what we have been going so far, the phenomenology.
Suchita Kulkarni: has not always been realistic, for example, we missed some particles with me some symmetry constraints, and that is something we've been trying to update in this study will take that first step towards.
Suchita Kulkarni: The other thing we should remember, as I said on the previous slide before all of these studies will you have used, we hear it here, and I wish I basically in brackets all the time, tried to mention the version is either listened to 3.7 or greater or pto on Tuesday okay.
Suchita Kulkarni: Now, with this as a starting point where we've done things you know completely signature based approach and varied everything that we thought were three parameters of the theory.
Suchita Kulkarni: You can think about.
Suchita Kulkarni: Whether we can do one step better, and this was one of the things that we did in the snow was paper.
Suchita Kulkarni: One of the new things we did, of course, we also have if you have all these existing strategic existing efforts in the mark.
Suchita Kulkarni: And in this case, basically, considering the master generate for me on the theory, the first thing we have to remember is as long as you're dealing with a QC need it.
Suchita Kulkarni: It has for free parameters and they are the number of colors the number of flavors ratio, which is dimension less, which is, for example, here, we take the most of the pie on.
Suchita Kulkarni: A scale and that screen which fixes the rest of the theory okay this game could be any parameter that you can fix to your liking, and for very good reason that i'll come back to me later on the scale, which was here is the dog, which is the confinements.
Suchita Kulkarni: We often think about these theories as QC like what is usually like really need you see like really means that the running of the coupling constant and this.
Suchita Kulkarni: Is a simple typically free Okay, this is like a kiss your standard model city like running and this is something which is very important, and if you take this and actually try to.
Suchita Kulkarni: understand what kind of nc and if you can pick so that your coupling constant is always in the same political regime.
Suchita Kulkarni: Basically, you realize that you cannot arbitrarily very the number of colors and the number of flavors of these TVs you have a good number or a good control over these parameters and very systematic way of how to vary it in order to actually get it okay.
Suchita Kulkarni: Now, in terms of setting and see what we should remember, and this is particularly to be here and limitation of our own simulation tools at the moment.
Suchita Kulkarni: Is we cannot choose the dark age group to be too because technically it is a real age group practically It means that, in this theory the pylons which are the cookie was dates.
Suchita Kulkarni: are the same as the values which are that you can state that means this theory should have given five files, but if you put it in the US military to give you three.
Suchita Kulkarni: And that means you're not simulating these theories correctly, so do not say the number of the gauge to be.
Suchita Kulkarni: You should also always use the number of formulas to be greater than one because of one for me on theory has no pions so technically speaking, you are not dealing with theory which is clearly broken.
Suchita Kulkarni: And therefore, if you do well, and if equal to one simulation technically speaking, we don't know what we're talking about.
Suchita Kulkarni: What this light doesn't begin with is that it's not that we don't know anything about these theories, we actually can learn a great deal by the amount of work that has already been done in the Community.
Suchita Kulkarni: In from different sources, and therefore we can set up consistent guidelines for doing us relations, for example on this slide I showed you in.
Suchita Kulkarni: The next thing you say Okay, I said I mean see what what we do with the mass spectrum of material, can I just put my sister way I want turns out even that can be understood by looking at the first principles understanding of this.
Suchita Kulkarni: If you're talking about.
Suchita Kulkarni: Su Su in theory it's some digital again said to each group to be greater than greater than to pop up at the moment, and if you have enough dark number of master jewelry box you this theory will predict that you have enough squared minus one number of messages across and.
Suchita Kulkarni: And, along with this, you have one single.
Suchita Kulkarni: Article and one single it's been one article, if you think about it in terms of standard American city, this is going to be your pie on my template which will have eight points.
Suchita Kulkarni: And then you get an eater prime which also you get in q3 and that's going to be a spin zero singlet and, similarly, for five or has been one single okay.
Suchita Kulkarni: You can set the masses of these particles very nicely basically by.
Suchita Kulkarni: By doing fits to the data to the lattice, and this is something that we did with it so much easier plot here, where we fit it to the mass of the pie on a new.
Suchita Kulkarni: dimension least most of the pie and Andrew and we've come up with basically our relationships so once you pick empire by Lambda.
Suchita Kulkarni: You can derive the mass of the quality of the theory and you can also realize the most of them, so there is actually a very nice way of setting parameters from you, we are the number of the number of flavors the quartermaster confinement scale and the masses of the pie.
Suchita Kulkarni: So this basically gives you some constraints on the parameters space, for example, the ratio of the pie, on most of the.
Suchita Kulkarni: scale Mars should be between four and five to two and you have to pick the SCI fi monsters longer dark ratio about 30 greater than 30 years in order to actually get to the Church.
Suchita Kulkarni: We have currently ignored any treatment for single any special treatment for simulator we have currently ignore everybody comes in okay.
Suchita Kulkarni: Now, how many phones, do you take, and I said they gave arbitrarily turns out not to be the case once you fix that most of the hills kind of pions.
Suchita Kulkarni: You basically end up into different regimes, one where either the whole to pipeline issue is open and if there are two pi pi DK movies open the rules will dictate to pile and there's nothing else you can do.
Suchita Kulkarni: To pi pi the camera is not open and if you set up your up parameters correctly, then the home is on the neutral, one of the neutral rules can mix with the supplier of utility and decay back to the standard model.
Suchita Kulkarni: And we had so far is that the diagonal rules will remain stable that is actually not true, the diagonal actually deacons were 340 DK.
Suchita Kulkarni: Due to the anomaly in the theory basically what this does is that once you understand the UV purity and once you understand what are the broken and broken symmetries of this theory and the cadillac ranch and analysis.
Suchita Kulkarni: You have fixed all the parameters, including the UV sector, as well as the sector and the dq, most of all, the measles, of the theory you're talking about.
Suchita Kulkarni: So the three already case is something we're not done identity so far it's something that we realized, for the first time it's something that we've tried to detail in this document.
Suchita Kulkarni: and basically once you end up with the three body decay you realize that the whole response can potentially be a long article because it's a three by three options, each time you see prime is very heavy the rules for a very long time.
Suchita Kulkarni: Which means that needs to have a possibility to have different DK boards for different reasons, and you need to have different lifetimes for different rooms, and this is something that was not available in the pto eight module prior to the current for.
Suchita Kulkarni: The second thing is i'm now current concerning the pions you can depending on your team led by on became the standard model or you can keep them stay with.
Suchita Kulkarni: The pylons really get the standard model they mix with the longitudinal more of this, in other words, if they get a mass from a higgs particle that also gives the most of.
Suchita Kulkarni: These are not details of the construction of the theory what it actually means is that, depending on how you choose to construct your theory, the amount of signature space that you can get in the low energy is a very fast, and we are very, very defined function of your reconstruction.
Suchita Kulkarni: What we was young, so what we can ask you is that there is no mixing between the dark, while at the same time and that's fabulous and stuff dogpile, at least at the scale of the.
Suchita Kulkarni: So long I kind of understand how to set this here in you really understand a little bit about how the UV to iron parameter ization is working.
Suchita Kulkarni: You want to go and test, but unfortunately you you you, you have a one tool and be a tool that is limited in terms of controlling the characteristics of the low miss on masses that you want to control of it.
Suchita Kulkarni: So, fortunately, because we had pity on us in our in our own doctor was Group and
Suchita Kulkarni: All the timing for.
Suchita Kulkarni: The bd authors were actually very nice to make.
Suchita Kulkarni: A substantial improvement in the picture.
Suchita Kulkarni: which led to a new version of.
Suchita Kulkarni: which gives us better control over the masses of the marathons in the low energy and what we also did was to validate this model basically to verify that if you have a master generate through and apply.
Suchita Kulkarni: The the rate at which these particles should be produced are very similar we validated that you can reproduce standard molecule city, if you go into the appropriate ratio and that reproducing the standard molecules that one had to do a bit of.
Suchita Kulkarni: I just mentioned, the menu string we need string fragmentation function, but this was all done by the potatoes, we validated, we understand what the differences between the old and the new versions are, and therefore we have reasonable understanding and reasonable trust in the tools that.
Suchita Kulkarni: I should mention here, but not validated the organization model at the moment, but we, we have.
Suchita Kulkarni: We have ensured that it produces standard mortgage you see in the appropriate for the modernization of this doctor is something that is still largely.
Suchita Kulkarni: An open question.
Suchita Kulkarni: Why should you care about doing all of this well for one for for for a first primary reason is because you if you're talking about.
Suchita Kulkarni: Creating checks at the let's see to all the process of partnership, covering and modernization, the dark coupling constant runs this coupling constant is running is controlled by the landlord, which is the confinements to scale.
Suchita Kulkarni: And therefore, you have escaped the TV and you need to understand how this fits into the rest of the physics that you're dealing.
Suchita Kulkarni: More spectrum of your dog nissan's depend on the dark or muscles, therefore, there is a relationship between iot up physics quantities and you should take into account.
Suchita Kulkarni: You can quantify using this knowledge, you can try to quantify urbanization uncertainties and this organization and so, if it is limit your.
Suchita Kulkarni: search power, therefore, you should care about it, and it also leads to new phenomenology like three body is not so far identified or a phenomenology and spins you know similar to, and one single edge, which also we have not identified.
Suchita Kulkarni: um.
Suchita Kulkarni: Okay, so with this, I have another little time someone to go a little bit faster what it basically means in practical terms, is the phone.
Suchita Kulkarni: We have here, for example, to physics, research, one which looks a jet substructure variables on when one, two or three pounds begin in.
Suchita Kulkarni: Three flavor theory and we can identify how these differences are and we've been trying to identify what should be the discriminating power.
Suchita Kulkarni: Between the standard model q3 background and such kindness just.
Suchita Kulkarni: jet substructure variables what you see here, if you have a lot of the tree already case instead of to Bali DK you get very different kinds of behavior in the environment more spectrum, and that would mean that.
Suchita Kulkarni: You basically your observations could be very different and that's something which is very interesting to explore.
Suchita Kulkarni: The other thing that I also realized, is that the substructure variables that we are using for the analysis, some of them, for example, ptsd and actually not infrared.
Suchita Kulkarni: Safe quantities and therefore you have to take care of what kind of just substructure reverse you're using and whether they're actually the same thing for us again it's.
Suchita Kulkarni: Okay, so that's basically the kind of progress that we could make on the on the side of your screen I carried and.
Suchita Kulkarni: that's basically more or less the BP amount of time we have for these progress in this no man's life back, but we also had a very nice dedicated to for also swept.
Suchita Kulkarni: Like signatures which are signatures in the large coupling with all four times and say Doc is very large these lead to suppress large mammal radiation and.
Suchita Kulkarni: Basically, the White sugars theoretically very small class of these theories have been proven to exist, so I think, a very interesting.
Suchita Kulkarni: class of theoretical studies that can be done in order to understand what these theories could be what can they exist, and so on, so forth it's a purely theoretical development we didn't go into that.
Suchita Kulkarni: But, also, that means that we don't have any dedicated simulation tools and there are some approximate realizations that existed right.
Suchita Kulkarni: Using these approximations you can basically try to simulate these theories and basically rely on the shape of service that serve as a useful and August right so, for example, here I show you what they called us, to say the city of the of the isotope we have this web.
Suchita Kulkarni: analysis or the final states and.
Suchita Kulkarni: Essentially.
Suchita Kulkarni: The difference between these two courses, this is before any trigger this is after any trigger and once you apply the trigger basically district strategies, create.
Suchita Kulkarni: bias towards less political events, and that gives us very good direction of thinking about and it's essential for the series triggers triggers us with play an important role in identifying certain types of events.
Suchita Kulkarni: You can also have beyond usually like serious in terms of glucose is interesting because.
Suchita Kulkarni: They are going someplace no no brilliant series series which contain no formula so skaters i'm not actually going to go in details of this time because I realized later on that caleb is going to talk all about it in the next session.
Suchita Kulkarni: I just want to briefly flash aside and say that this exciting venue has started to be explored in theory.
Suchita Kulkarni: There is a public pool, which gives you some amount of freedom in setting the modernization settings and therefore exploring what could or could not be a lot more theory development can go in this direction.
Suchita Kulkarni: At this.
Suchita Kulkarni: Finally, we also looked at what can you improve in terms of just sort of strategic it's not something that i'm expert in this goes more in the direction of machine learning This goes for the direction of really experimentally.
Suchita Kulkarni: look forward looking analysis, so I spent literally 30 seconds on this slide saying that you have.
Suchita Kulkarni: Measured pathways in terms of defining discriminating variables defining new triggers and use some voice.
Suchita Kulkarni: or on auto in color type of machine learning techniques in order to discriminate between the standard really backgrounds and.
Suchita Kulkarni: dark jet or swept lights emitters, because what you want to do is to really look inside the event shape and try to understand what is different between what you're seeing and what standard we can give okay.
Suchita Kulkarni: And there's also a lot of discussion about this in the in the literature, as well as introduction was paper here and, again, as I said, i'm not really a very.
Suchita Kulkarni: Very well informed person about this topic i'm not in the right person to talk about this topic, but I do want to mention, and this is something very exciting very forward looking.
Suchita Kulkarni: And we should try to explore it more going into the future, so whether they start shoveling snow was standing this this moment.
Suchita Kulkarni: We still have the version two of the White Paper in progress.
Suchita Kulkarni: We do have a number of things which we wanted to finish during this was our part we haven't.
Suchita Kulkarni: is something that we still are interested in in pursuing still interested in doing I missed the the bullet points here but i'm not go through all of them for the lack of time, but you feel please feel free to read the slides and voice your opinions on this.
Suchita Kulkarni: And just briefly share totally unbiased event advertisement there is an upcoming workshop on some invisible chats i've linked of indigo website.
Suchita Kulkarni: Please, please feel free to contact organizers in case you have questions myself being one of the organizers and therefore the advertisement being totally unbiased advice.
Suchita Kulkarni: Okay That brings me to my conclusions and I will again not spend a whole lot of time going through all of the conclusions, basically, the point being a.
Suchita Kulkarni: strongly directing doctors are interesting because they can explain stir shortcomings of the standard model and they provide interesting supportive of the experiments.
Suchita Kulkarni: We have critical mass, in order to drive this program, and the reason we should use it, both on the funnel and the experimental side in this context, we did.
Suchita Kulkarni: A project on doctrines in the snow mask context we surveyed existing models, the overall.
Suchita Kulkarni: event module we have new understanding of these theories from you, we do is we propose some few first benchmarks.
Suchita Kulkarni: But we also have been beyond this survey what is on the market in terms of event analysis for us in terms of new variables and new methods and we also discuss what would happen if you go beyond his emotional in terms of signatures loops and.
Suchita Kulkarni: Finally, Richard remember that a successful exploration of these theories can benefit from understanding on the underlying curious.
Suchita Kulkarni: can benefit from talking to other communities like like the simulations and furthermore it's really an exercise which brings together community from standard model to city from from knowledge articles from.
Suchita Kulkarni: Experts, as well as experimentally so working together so with that I thank you i'm sorry if I wish over time and I would like to finally put towards having a very big thank you to all the contributors to most people without which is not possible, thank you very much.
José Zurita: Thank you, such a.
José Zurita: Nice presentation and trying to condense the enormous amount of work of so many people in a in a slight so we open the floor for questions.
José Zurita: So she so so far, I see no canceled so let me have use of my powers of convenience, to ask you something so.
José Zurita: So, essentially, one of your first argument is you know we have except prime that mediated sectors, this is fully accessible to seeing the outcome formula paid for another doctor what PayPal.
José Zurita: But, in principle, you could also use the standard model hicks as a mediator, with a sector, so you have two less parameters right and probably much more because you have said plan toppling.
José Zurita: Essentially, free so is the is normally does not consider because, for the lsc you tend to get started, is way too soft and then it's hard to see or because I remember finding testing the.
José Zurita: dice our benchmark paper from Simon napping and Jesse they did consider some sort of exotic that a shower for my next 30 he's the game.
José Zurita: A body wasn't the core of the pavement so I don't know if it has only to do with the fact that they prefer salty or is there any other reason why the construction, with the same premise is prefer.
Suchita Kulkarni: Okay, so there are several.
Suchita Kulkarni: ways in which I can answer this question Okay, how do you construct a theory that has a hex that mediates interactions between standard model and the dog sector.
Suchita Kulkarni: The one easy thing you can do is you charge some of the dark circles under the standard model and then you have basically a photo you can use.
Suchita Kulkarni: To put it simply, use the standard model has to be a monster the dark works okay.
Suchita Kulkarni: As soon as you start to do that you're basically heavily constrained by several different experimental searches, as well as considerations of things like magnetic monopoles.
Suchita Kulkarni: typos and stuff like that that will push the the mask is of these theories very, very high okay.
Suchita Kulkarni: So if you want to have like new physics that talks to the standard more than wire hits by charging a part of that sector and the standard model I think you're in a bit of a tough luck here The other thing you can.
Suchita Kulkarni: Do is, for example, you can introduce um I DAS kits that makes us with the standard model it's this dark hex gives masses to the dark sector quarks or something like this.
Suchita Kulkarni: And there is a probably there is a possibility of cooking up something in this direction, where you have a text analytics mixing and and.
Suchita Kulkarni: Then the standard model hits the keys to the to the doctor particles, the third possibility, in which you can do it is, for example by constructing something like H2 accepts searches, I see matt has a hand up I probably something which is not a correct argument not give me a second.
Suchita Kulkarni: And the other thing you can do is you can construct something like an H2 XX agency fluency literacy prime decay back to the standard or the dog sector if you can um you can.
Suchita Kulkarni: control the hierarchies between the zebra mussels and confinement skill sets that you can still get the jets out of it, I think this is also possible scenario where you can.
Suchita Kulkarni: I don't think there's a very specific reason for why is the prime is preferred I think it's preferred because it's the simplest thing you can do, but that does not rule out additional thoughts what it necessitates is we understand how to set these parameters, going from top to bottom.
Matt Strassler: yeah I think just.
Matt Strassler: Just to elaborate on that and and it's it's.
Matt Strassler: You know the part of this is historical and part of this is phenomenal logical.
Matt Strassler: there's certainly no reason at all that you can't have haters decaying to dark jets but.
Matt Strassler: First of all.
Matt Strassler: If you want to do all hydroponic signals which was driving some of the interest in some part of the Community Okay, then.
Matt Strassler: You most of the time people aren't at first of all people haven't been so interested in purely heavy.
Matt Strassler: flavor, which is what you would get from the higgs so that can be complicated, and also because the higgs is light the jets don't have a lot of.
Matt Strassler: don't won't have a lot of particles in the evening won't really be jets.
Matt Strassler: Unless the confinement skills very low, but then that makes the lifetimes long so then that becomes an nlp project and not a semi official projects project, I mean it's, not that this can't happen, but you.
Matt Strassler: You know, it depends, which Community you're working in and and who wants to study it.
Matt Strassler: There has been plenty of work on on higgs decaying too complicated final states in the context of lifetime jets which, which is you know so so.
Matt Strassler: The answer is definitely yes, but now we have to talk in details about okay what signature, do you want to look for is it is it possible, within the context of that one and so far.
José Zurita: Okay, thank you.
Matt Strassler: For the clarification.
José Zurita: want to see a model.
José Zurita: So, since we have no at the moment, but we have still a long session to roll on, I propose that we move to the next speaker series the violin I sorry for my from Anglo Saxon pronunciation.
Dylan Linthorne: Oh yeah no problem, can you hear.
José Zurita: me, yes, would you like to try to share your slides.
José Zurita: yeah.
Dylan Linthorne: Okay, can you see.
José Zurita: So.
Dylan Linthorne: You see, the presentation.
José Zurita: Perfect 10 years.
José Zurita: From now on, you in 10 Minutes will let you know you have to lift Okay, so please go ahead.
Dylan Linthorne: Okay.
Dylan Linthorne: So yes, my name is dylan i'm the one speaking on behalf of Paul Smith and Daniel strugglers fee on just a recent paper we've done so guys the archive here i'm just going to quickly.
Dylan Linthorne: go over as well, so the title is emerging justice place into the future, so emerging justice kind of the dark Sharon partners like the chocolate in the dark showering.
Dylan Linthorne: Section although displacing the future we're looking more of the experiment so just in the previous topic and I think Matthews point was that.
Dylan Linthorne: Depending on how you're looking at in terms of the private sector, you can look at the shard regime, and then you can look at the LP.
Dylan Linthorne: So we're kind of seeing what we've looked a lot that we can see an atlas and cms now let's see if we can leverage any of the.
Dylan Linthorne: Experiments for for kind of typing down or C and merchant jets or dark QC in general, so the talk before did a great job of tackling keeps de.
Dylan Linthorne: Chao sector and showering so i'll kind of fly through the beginning, slides, but obviously dark you CD have some confinement get it sector.
Dylan Linthorne: That has some number of dark colors which can find that some juicy D scale to city like stale activity.
Dylan Linthorne: motive, you can motivate device metric dark matter where you have to say five times the size of the steps follow confining scale and you have some dark baryons and dark mason's with some lifetimes that don't dictate properly.
Dylan Linthorne: But you embed this in the hidden value right, so we want our spectrum in the dark ucb to be relatively light in terms of new physics, as previously mentioned.
Dylan Linthorne: So if we want to have that light, we kind of happen kind of sequestered and hit an often the standard model there's not a lot of communication, other than, say some.
Dylan Linthorne: Be heavy mediating portal or sorry production and portal, so this production mode can be stated that prime those spoke about earlier, this can be some scale or by fundamental maybe maybe a hex portal.
Dylan Linthorne: or it's a dark takes portal in our talk we're going to be focusing on or the studies focus specifically on what we call the scale heavy scanner by fundamental a big and this communicated some heavy scale between the standard model of the CB.
Dylan Linthorne: Richard.
Dylan Linthorne: Space and this dark you see the hidden valley has you know some simplified spectrum, which we can simulate through the Monte Carlo in terms of the hidden valley module.
Dylan Linthorne: So you know we we case very standard.
Dylan Linthorne: parameters that we've used similar the original original paper and a few others, where we have say seven numbers seven flavors of dark.
Dylan Linthorne: dark sorry flavors and three.
Dylan Linthorne: dark colors so we have say unstable dark pions me have properly decaying and guard gross so really we focus on our dark the dark pions with a dark cloud on analog as the The long list particle of assess, so this is when we receive showers with displays vertices and the dark grows our.
Dylan Linthorne: Property dictated the dark paths, so we follow this kind of just systematic way of for advertising the hidden Valley, where we have the client side, there is a function of the dark biomass and abroad BATs at the dark QC deeper constituent.
Dylan Linthorne: Sorry constituent court masses, so we kind of consistently take that throughout the paper.
Dylan Linthorne: So.
Dylan Linthorne: Heavy media, why did we choose this by fundamental well it's convenient because this this by fundamentalists produced in production.
Dylan Linthorne: So when we have this produce in production we actually make the production cross section, independent of the coupling of the dark sector, so if we had a vector coupling to.
Dylan Linthorne: Set prime we would have this dark coupling come up in terms of the production process section, but since we're going to be at estimating sensitivities that these llp experiments this pair production scale or.
Dylan Linthorne: Cross section can be estimated usage.
Dylan Linthorne: square production cross section and just knowing the number of dark colors do you have a second so.
Dylan Linthorne: Then we can talk about the show, so this is a plot.
Dylan Linthorne: shot earlier, which was mighty cute little protons barrios sorry I made sense.
Dylan Linthorne: Here you know medically we're showing the the production is that prime but that could be any production mode.
Dylan Linthorne: We have that shower naturalization the dark check shower that again, we can do through Monte Carlo and now we understand, to some degree showering better than the hybridization and the QC QC the like regime.
Dylan Linthorne: Less than a soup, so you know this decade, either could be the same as the direction media or something else, depending on the model, but then we have some long lives.
Dylan Linthorne: articles in our case, the dark pions that decay back into the standard model that we see today, so we take the decline of the standard model of be 100% in terms of qq bar.
Dylan Linthorne: So we really just kind of can look at the dark clients themselves and kind of investigate that in terms of the parameters for stephanie so the dark pile on that became.
Dylan Linthorne: lifetime can be prioritized in terms of saving massive the mediator, the TV scale, the actual methods that are cons some constants and the QC QC decoupling.
Dylan Linthorne: But really this these privacy really be summed up in controlled by industry right, we had a massive the media, the mass of the dark and and.
Dylan Linthorne: So those are the controlling parameters for our phenomenal logical study and everything we've done the previous papers, has always been looking at the.
Dylan Linthorne: kind of near interaction points at a cms studies and then CP so with that we kind of get a shower aspect right, we can shoot a shower and we close the interaction points we see this this place vertices more cluster together lower opening angles.
Dylan Linthorne: But what happens if these lifetimes or crispy long say, along with Ben say meter.
Dylan Linthorne: We get more characteristic I love pizza kids so now we're going to be looking at what happens the slob dark pions as they exist much longer than we see it atlases tms and kind of see them of them was an individual lps at the.
Dylan Linthorne: Future Long live particle experiments so here's just again the previous work, we can you know, mostly about that lesson cms that we're looking at the more you know llp.
Dylan Linthorne: Experiments that are either transverse forward upstream or downstream here my very simple schematics of how I view them as boxes that cylinder is, which is kind of.
Dylan Linthorne: motivated how we did our detector about to Carla.
Dylan Linthorne: But we've looked at a few obese so we've looked at a few of the transference of the few before just kind of sample space that seemed appropriate of time, as well as the proposals that we had an access and actually translating something to produce.
Dylan Linthorne: constraints and sensitivities so.
Dylan Linthorne: to spoil.
Dylan Linthorne: Our results was it seemed that the transfers detected are much better than the four detectors for the pair production, and this is kind of you know, motivated by this Nice and I plot, that was the previous workshop.
Dylan Linthorne: The chocolates why so modality two factors it's kind of like broke down the search.
Dylan Linthorne: limits or ranges developing masses or a lot of the transmits detectors at some of the four detectors in terms of the distance that interaction.
Dylan Linthorne: So.
Dylan Linthorne: We also produce you have like a lot in terms of the Phi theta range of just looking at how differently these these experiments kind of cover in terms of the Angelo space.
Dylan Linthorne: The Codex be is shifted purpose they just sort of overlap with the others so we've actually kind of differentiate the different experiments and then obviously before detectors are so small, in terms of that that Angela range that you can't even see them on the spot.
Dylan Linthorne: So what did we do well, we just estimate these these detector acceptances by just simple Monte Carlo, so this is kind of just been kind of like the standard.
Dylan Linthorne: procedure for a lot of the papers and look at these llp projections, a lot of them use analytical methods we did something just a little bit more.
Dylan Linthorne: Different where we just actually created an actor volumes very simple detector volumes and just look at the detector acceptances given the pithy events that we feel to it.
Dylan Linthorne: But it's really just based on a branch of ratio to the signal again, which is basically 100% in terms of the dark dark pontificating to qq bar we again the probability that the inspector acceptance acceptance given by this expression that distance from the.
Dylan Linthorne: detector sorry entering the director versus leaving the benefactor based on the clues to the particle.
Dylan Linthorne: is estimated through a little Monte Carlo and then we know the production sample size, because we know the production cross section of kids were using the.
Dylan Linthorne: scanner by fundamental as as our media channel.
Dylan Linthorne: So in this case, we can.
Dylan Linthorne: Look at the the contours of the number of the cave dark house that we expect to see in each one of extravagance.
Dylan Linthorne: Based on the luminosity that they project, as well as their assumptions on that property right, so you know, there could be some contention on like are these execute background free.
Dylan Linthorne: know that that's not for me to say more realistic Hudson criteria is has been talked about for the different experiments so say for Alex and code I speak there of talks on how she.
Dylan Linthorne: tagged or cut on number of tracks based on how to diffuse the energies are hollow the pts are so this is one example for one of the cuts for Alex they proposes, you know if we have some number of tracks, with some never PT.
Dylan Linthorne: We can see that you know it doesn't change the course to too much, but depending other machines you're looking at.
Dylan Linthorne: But yeah these these all soon background free without this this Rico line so given that these are background free one can say that these are representative of the confidence intervals for and greater than three.
Dylan Linthorne: But just looking at the plots, we can see that you know the lifetimes of these as a function of supply times we expect to see majority of the case happening.
Dylan Linthorne: When a dark pile is much lower than and greater based on the boost you know emerging just create high more complexities larger the multiplicity, the lower the energy for pop dark pi on, and as we lower the massive time we also lowered as well.
Juliette Alimena: Sorry.
Juliette Alimena: You have about a minute left thanks.
Dylan Linthorne: Oh perfect.
Dylan Linthorne: Thank you, so I have one more slide So these are just our contours.
Dylan Linthorne: But then you can also look at, just like the visible.
Dylan Linthorne: At the Cape rocks at them as well, and you can also try to look at you know, maybe what are some best cuts, we can use Facebook visible in the case of our clients, so we also just looked at hga distribution of what the starcraft.
Dylan Linthorne: decay into for the experiments and this can be used to kind of estimate David what are some great cuts or tagging we can do when outside of just looking at the rubric the case and.
Dylan Linthorne: we've also looked at before detectors but they're only sensitive to channel so but I won't talk too much about that.
Dylan Linthorne: But in that case it's a channel that we're looking at in terms of the media exchange is not independent that dark complex so it's hard for us to put anything more than just a luminosity probability constraint on there, or a projection So, in summary.
Dylan Linthorne: just say that emergent doesn't always produce something novel and trump's of signatures and the theory landscape for low lifetime regimes, but.
Dylan Linthorne: Do limit traditional basically just the high lifetimes and we can probably that hopefully the future LP experiments.
Dylan Linthorne: transmits detectors are more sensitive for each agent jumps to the traditional production that we're looking at, and then the TV channel scale or exchange does it enhance the sensitive is in the form of education.
Dylan Linthorne: regime, but we suffer from the dependence and trips to the dark cutesy decoupling scale, but yeah so that's all for my talk and if anybody has any questions, please.
Dylan Linthorne: Try to figure out how to.
Dylan Linthorne: For any questions.
José Zurita: yeah we'll see if there any fans, but I guess in at five The session was a great idea.
and
José Zurita: Do my so Joanna Please go ahead.
Giovanna Cottin: hi thanks don't i'm not sure quite understood when you calculate basically the same.
Giovanna Cottin: We want the gallery capabilities for your energy to regain within service within the acceptance of the different part that that.
Giovanna Cottin: Transfer sectors, but then you have another efficiency there, which is like.
Giovanna Cottin: Hot in your formula, so I understand the acceptance, which is like the average probably needy, but then this efficiency, how do you look, for example, for Methuselah, how do you quantify this is sort of simulation beyond.
Giovanna Cottin: Like the doctor simulation yeah.
Dylan Linthorne: yeah, so this is so, this is everything in terms of just the probability of actually getting the K into the detector.
Dylan Linthorne: That doesn't tell us anything about.
Dylan Linthorne: Whether they will say measure the This is like decaying products from that so, and this is more of just like a cut efficiency so it's a way of.
Dylan Linthorne: Saying well, based on the physical attack physical energy or the physical tracks and the the volume.
Dylan Linthorne: How likely, are you able to actually.
Dylan Linthorne: reconstruct that maybe they're there to diffuse low PT low energy and you don't actually measure that, so this is just basically efficiency of everything else other than just the probability that came into action.
Giovanna Cottin: Right so so sorry, so these hd so you basically do reconstruct the jets right.
Dylan Linthorne: yeah yeah we don't.
Dylan Linthorne: We don't reconstruct the Jeff in terms of like.
Dylan Linthorne: entry.
Giovanna Cottin: level information.
Exactly.
Giovanna Cottin: Okay yeah Thank you Thank you just want to.
Make sure I understand.
Suchita Kulkarni: answer one of my questions i'm.
Suchita Kulkarni: Sorry, you said you did the pocket I was distracted, can you please tell me again by for teachers, do you have more sensitivity.
Dylan Linthorne: So the teacher, yes, so in terms of the chief shadows change.
Dylan Linthorne: This is something that has been seen in previous.
Dylan Linthorne: Studies and with this is just something that we're seeing in terms of.
Dylan Linthorne: What our mountain probably gives us but.
Dylan Linthorne: With the TV channel you.
Dylan Linthorne: you're changing the the media, as I think in your previous teacher in terms of what we're calling our production so maybe there's like a discrepancy there, but in this case, but each of our exchange, you should have more boosting in the Ford region where it's.
Suchita Kulkarni: Exactly what i'm trying to understand because I would.
Suchita Kulkarni: Imagine the posting to happen, though sorry yes okay fine I understand sorry my bad yeah.
Suchita Kulkarni: yeah.
Dylan Linthorne: yeah, no, no.
Dylan Linthorne: It took a while to wrap my head around it as well, but yeah that what it suppresses the fact that we can actually get this actual cross section actually.
Dylan Linthorne: So I mean independent.
Suchita Kulkarni: Excellent.
José Zurita: Okay, well, so we think you both speak of position within the last conversation and we reconvene at six seats were slightly delayed.
José Zurita: So take a quick break and come back.
