Can you see can you see the slides?
Yes.
Okay. So, he has to not lose time this let me start a okay so first of all, thank you
everybody on also the organizers on the on the attendees to the token and also for
for letting me introduce these these very interesting topic and let me write
directly into it. And so let me first try to motivate what why I'm going to talk
about electroweak sushi or supersymmetry or why we why we are interested in this
kind of physics. As you will know, the we still don't have a very clear hint of we
understand that model physics in the let's see, but of course, we are not done yet. I
want to cover every possible every possible space, leave no stone unturned.
One of the things that the experimental community we have done in the recent years
is that we have been able to prove the strongly sector the strongly charged
sector of supersymmetry very thoroughly, a been able to push the limits on the play
Under strongly by targeting sushi partners up to the TV scale, and whoever the
electroweak sector as much as we are also looking into detail into very much detail,
it is it's likely a nice constraint at the moment. And also that's can be the the key
in finding supersymmetry or the let's use case, this because we know spectacularly
for the both in the past in 2016 data and and also the resources will be so in today
with with the full run to a statistics course introducing a new a new bit of a
new exciting is being saved in this strategy is to try to analyze the data and
to look into the most complex versions of time for example, marking here in with
these with these question marks that usually tend to go into all into into
regions which are much more complex to look at in terms of experimental status.
So if somebody let me Yes, go through a quick review of what kind of squared this
sushi what kind of supersymmetry, we are looking at. Hear me through using several
simplified models, as you all will know, this
is not a complex,
complete supersymmetry, supersymmetry realization is not a medicine but is
something that allow us to to parameterize what we see and to try to check the reach
of the different analysis and try to have a benchmark to to study the different
financial state, the different behavior of supersymmetry in the final estates we look
at and typically when looking at these electroweak sushi in general, these are
this kind of simplified model you have three big groups of final or final estates
or the case of sushi would you say there on the left you can see there is the
couplets with a couple they are unison we also have we only have like this leptons
see they're usually either stylish or all the flavors at the same time. In the
middle you can have the something that you see between the other two which is a it's
a unilateral copy both to the unison and this lifters, Aloma So you have the case
or the delay or the to go through these letters. And on the right you have the
other extreme cases these when they when these letters are very high mass or the
couple and you have these kind of finalists that usually stand there more
than motions plus plus A plus A B C or particles plus in this piece and a same so
here we are covering a lot of terrain with with with instead of just in Amazon cmac
I'll try to go over all of them try to highlight the ones that are more
interesting for because they are more new and they we can social comparison between
DoD and CMS but please take a look at all of them. They are all present very
interesting resource and very interesting things for for electro issues. You also
have to point out that sort of they're not technically too weak but the materials
we'll talk about them later in the in the software industry of supersymmetry took a
dive into the first part let me go into the things that I saw in the in the left
that are left on production. And as the first car highlight on getting resolved
today is this It's open to production, as you will know is the fact that a
supersymmetry with flowers lifestyle is kind of preferred in so on and so on in
some theoretical models because it matches some cosmological observations related to
the metallic density and as such, one typically thicker takes a look also at the
data of modems that are entreats in the house, a finalist a to SQL because
relating to the whole, the whole, this whole this leptons coupled to the rest of
all the stuff that was on the sushi, the sushi partners. And in this case, I'm so
in a zone ourselves from CMS and I searched for an atlas was looking at the
Cisco production, either in the one lift one or two or two wonderful plus 1000 or
2000 nikto final estates and this classification, just to justify it here.
And so in the main point to the main difficulties that arise from this label in
this case is the fact that 500,000 is pretty mentally scarred and so it's not
the same as looking at the electrons from you. For the discriminator to interview
assassin so here are the one lepton plus one final state, the target of the sort of
the difficulty of the search is trying to kill this, this misidentification of the
thousand became irrelevant. Remember about one of the sets. So the idea is to have a
very precise estimation based on a data driven on the tree or the Taliban a
procedure to estimate the department and then a use several body discriminants
Thanks. So here are the cases for the mu plus tau one plus tau channels for 2016
the other side in the workup and of course I can refer you to the to the proper
people hear what the underlying idea is that you want to have some powerful
discriminant that lets you separate these these kind of backgrounds from therefore
understand them all from the supersymmetry. So, for the production
signal, and if this is a problem in the one Lipson plus one hydronic Tower state,
it is more of a problem in the 200 activities because you can have to miss
identify those at the same time of course, and this means that they searches looking
at the 200 NATO for United States has to be tight, you have to look at faces places
that are much more targeted to the to this email to be able to have a noticeable
share solution. And in this case, I have here all the services by Atlas and CMS
looking into the final state and you can see that the strategy is very similar
basically trying to look at some reuse the third and the final way a set of tight
fiducial cuts, looking into regions that are able to discriminate that in the multi
year there catches me 75 of background on the TT one final estate and also relying
on data driven techniques to estimate this kind of complex misidentified out
algorithm to try to have a very precise estimation of it in order to be able to
later see the eventual supersymmetric signal on the right here and so in kind of
the strategy is also relatively similar in the worst cases. A harmless uses a very
tight selection SAP analysis selection to look at the final estate that is saved.
viewed, but also have some control of the organization seminar controlling is
related to the badness of time pointing in the left, when CMS tries to opt to use a
an extended feed that kind of does the same procedure, but looking into
discriminate several schemes, somebody was looking at the distribution of cyber
security screaming, screaming somebody was doing. So, in here in this distribution of
scenarios, as you can see, unfortunately, there is no clear hint of any kind of
access any kind of signal. So, so, always what we do is try to interpret these in
terms of simplified modems. And I feel here the interpretation from from Boston
in the left you have interpretation for an atlas on the right you have interpretation
from from CMS, and you can see that expected and observable results are in
perfect agreement with the the certainties and also let us start with this and want
to luminosity we start to be able to exclude several regions of the of the face
of space. I also have to point out the complementarity window in the searches on
saddlers is able to go a bit farther in range also looking at the motor final
status statistics while CMS they will use it to fly late to the cluster school
loaded into PT also gets gained some insight into into the lower mass. So, at
the end what searches are very interesting most searches provide a very similar
result in the ball can also provide expansion in differently use on the face
of space providing complementarity between the two experiments. A note highlighting
nice as there is little time, but also in the point out to show an older new
interesting results in this let them finally stay in this little production
This is a result from the Atlas collaboration looking at too late to final
state. And you can see here that of course, once you are not restricted to the
final state there is typically increases because we are much more sensitive in the
sense that we are very much we're much more able to obtain precisely positional
results with electrons and means, again, a very interesting result that is able to
force the limits or the discretion limits on on left on his left on production. The
700 DVDs which is much much more than it was and ready for the for the TV response
in the wrong one so also recommend to check it for you to check it out well let
me go to the second set of results which is a sorry and it's a you know personal
trainer production. And first of all let me let me highlight one set for another
that is also very new very recent they in fact, I think it is not yet fully Casitas,
but rather will be pulling during this week. At this using the full run to
luminosity looking at three and a final estate with three leptons either in a WC
like Final estates or having something that behaves like acid or in a wh like
Final estate that is basically going for a of the peak or the when looking at the
body mass of a of an alpha of an electron pair. So when entering into this at peak
or of the set peak, you can either select wha wha wha wha like the police and this
analysis due to the careful estimation of the YWCA is completely needed if you want
to have a precise measurement and I ain't showing here a controller you're on a
valuation ratio, the one on the left enters in the feet. So, this kind of
distribution centers to constrain the W set background while the one on the right
is just used to validate that these feet they truly predicts what the Standard
Model look like looking nothing other than that the signal depleted but does not
enter into the feet and as you can see, there is great overall agreement between
the two.
This is also the distribution for the cells in the signal radios. On the top you
have the one looking at WC like the Apollo is again and this is a very complex final
state. So it tries to go thoroughly through the all the possible final listed
topologies looking at a difference you know, yet or higher circle activities
which are low or high at and then trying to use several discriminant Baria wants to
the to the frequency the different blocks you want to find a list of topologies and
the train is known at the bottom for the wh like Final estate is very similar
strategy but it also includes Radio with small access, nothing exciting, nothing
special exciting, but this small access is there. And we'd say when you look instead
of looking at say some things that have same flavor opposite sign a laptop, or you
have a different flavor differently, what have you seen sign a bear, which is
basically these two final beans here. Again, a relatively complex analysis
looking at all the final different final estates. And then we go was there is no
expansion exists, either in the W set final estate to the exclusion limits. I
also pointing here out one other unless it's on the right, which is their code,
the affiliate or final set of instances search, looking at their currency, exotic
construction, what do you think, also very interesting, and I also, I'm sorry, I
don't have infinite time to cover it in detail, but basically, you can see that
they will certainly say allow us to push everything even farther to the limits in
the in the possible possible is particle masses up to the 600 700 cubits for the
for the 30 nanometer matters, I also have to point out again the complementarity
between the two of us also both are statistically dominated having differences
of sorts. So systematics a the WCS background or different uncertainties
related to this recursive reconstruction algorithm means that more searches can be
improved with with different treatments or systematic so at the end, very interesting
to choose two topics to look at, for the for the field. Before so we do the
interpretation of the whi final estate. I also want to highlight very briefly,
another fine I know the results from both Atlas and CMS, which are the one looking
at two Hama final estates. And the idea in both cases is to look at the case of the
fees to two to 14 which is a typical a typical fee to have his standard model
measurements. And the idea is that you can look at the took take this as a handle to
look into associate the production of a case with any standard model also needed a
W or set or x plus a paid off lsps Looking into that with a lot of cmas try to
classify these possible services depending on how the other particle that is produced
with the things the case. So, a there who decided only Carla Tony they said that
these are the only coral tonic and they other things that they say the other only
call trying to look into more inclusively because you can also have the Higgs decay
through double use on sets which also produce leptons. Both the both analysis
try to cover different emphasis spaces and then also shown over labs which is very
nice to check the complementarity between the two, but at the end the procedure is
relatively similar as they also try to fit through these kind of analytical
analytical feeds you look on the on the right with both the signal and background
are fetus. So, certain analytic functions that relate to either the restaurant
contribution or the non racial background, you can have here and at the end both
analysis relatively similar in concept but look at some, some different ingredients
and also provide some differing insight into into the into supersymmetry. This
analysis as I said also look as the wh final estate, so, it can also be compared
in terms of reach we feel left on analysis. So before in this case and so in
a so in here they is the exclusion limits for several analysis, also a new one that
I will have time to show which is also by enlarge this one lesson plus,
plus movies. And you can see here that,
while this last one is the one that dominates in the bulk of the of the
selection, and that is in fact, it's when it's more successes here, we also have to
take a look at the what all the analyses bring into the table which are for example
for the children McKay's excellent separation between seen on the bottom, as
you saw an insight into this query. Also, its analysis has its own peculiarities and
improving one it's related to having to look into different kind of systematic. So
again, all analysis provides some insight in different regions and the
complementarity between the three is what gives us real power into into these final
estates. There's going to the conclusions that you say have to highlight that is
great quantity of high new high quality responses to service during the last year.
But
I have to tell you that there is more still to come forward. So stay tuned and
try to have an eye open looking for for these three have been filled every three
years research that is the electroweak supersymmetry. So point here are links to
link of the communists have this issue and say it so I will be there during the
coffee break, in case you want to discuss something.
And also
yesterday, let me finish by thanking you for your attention.
Thank you, Carlos. Do we have any questions from the attendees? Okay, um, I
have a question for your spouse searches. You mentioned the benefits of the laptop
plus hydronic towel channel, but how much does that channel actually add to the
sensitivity of the analysis?
I don't have a quantification of it. Really. I don't have the numbers. mind
then they're like you need the idea when you go to the to the apart from the fact
that the final estate is cleaner so in a sense is typically easier to to look at
you have lists lists a list originating from dismission and defined house you also
can typically always
slightly lower on PT because you can
you can reconstruct lower PT letters the proper number I don't have in mind the how
much how much you really
I don't know I don't know if there is also a Radia
this plus Harvey I don't think they have in a split why we finally state this
crucial prospect maybe I'm wrong
okay. But even if you I mean with the left hand plus hundred on the top trigger, you
can go that much lower in the in the left hand thresholds right because the trigger
is limited by the hydronic towel no fight left on
yes only for for that I guess if you want to really look at this these phases phase
here in the In this video, I think you can see my mouse. You probably want to take a
look at at Mattel stock for the thesis of sushi Utley.
Okay, thank you. Do we have any
