Okay, okay.
So
good afternoon. Today I will try to make a short review for interpretation term. So
dark matter models are results of search for Harry's analysis. And he says beyond
the Standard Model ideology
and
is a blood of my dog. I'll touch some to be connected to electron scalar media
properties in different models. And I'll start from a very short introduction to
effective approach to that model.
And
effective approach, what they were doing and what can we do here? What we have is
just various approximations, effective simplified considerations. What can better
or not describe the main features of possible introductions and properties? The
simplest and the most economical way to introduce the Dark Sector into installing

examples, zeros and one yet is not quite ordinary properties. Suppose for example,

effective extensions to HTM plus a and two HD composite prime? In both cases, the
number of possible processes is that matter and mediator saw visibly increase

After the mediator, but both of them
can be coupled to a standard model is completely case with description and one
such example I will give at the
end of my talk. Finally, a dark matter can be much more complex and different. In
particular impact particles of dark matter cannot be fermions but can be vector
scalars I'll look at it but such models are also studied in relation.
And here I give a list of possible signatures for different spin one mediator
but fully visible final states such as
digests and to barbecue bar resonances here, and although final stages missing,
there are common for all modal signatures related only to the area of mediator spin.
And there are model specific only for a conquered class of models. It's a general
rule an extended to specific models contain additional lines and diagrams or
specific realities.
And transitions. For example, you can look at the very simple case for his prime and
simplified model and compare this to a more complex case into 12 to 18 plus prime
alliances you can see lines with additional haven so to scatter Higgs and
underground full flavor relating process with transition UT for flavor and religion
exchange. Usually search for mediator contains completely untrue studies on
visible channels, and I will touch on the lines, underlines signatures, and we'll
give some some reference though.
Okay, let's start with that a channel is a nice fully visible signature with the loss
to find resonance or opt in limits on the mass and define the interaction constant
with a standard model. What it doesn't allow you to do to obtain limits on dark
matter
So since we are no participant in the process in this case, they're all brought
digests resolved or nurtured reconstruction is flower notification,
there are different techniques and experimental instruments sorry.
And when we talk about digits You can also add them in general case in one mediator
can also depend on the left and final states. How for Victor mediator not for
actual vector but for vector media. There are strong experimental limitation coming
from a young process study, so a mediator is often considered as lipophilic.
In general engine utilize some simplified description the cross section of such a
process depends only on two parameters immediate and coupling to work full of a

more problematic region of floor and in various places require some special
techniques.
This is an additional option
For third read from initial authorization to increase experimental sensitivity to
softer jets mask by a large QC background, as well as some special techniques for
trigger and online recording goals to use. All of these make it possible to
reconstruct the jets and to push down the experimental sensitivity to digest and
variant masks as small as about 10 gV.
And now a problem arises when our Spillman media becomes too wide and narrow with
approximation can be applied. It happens roughly for a ratio for little these doors
and as mass of about 10 maximum 30% then in our signature can help us it's commonly
used for non resonant deviations from standard model with angular distribution
of digests. Using the signature allow us to move on to Cochran courage on the order
of unity.
So this summary contains a generalized plot for Atlas and

Limits obtained from that channel can be combined with data obtained from analysis

So, the same results same various inputs for vector mediator previous slide was for

Okay, let's move on to more complex models
and Jocelyn Firstly, start from somewhere specific signature. As I said before we

again there's your letter for the mediator with couple of minutes, which is corporate

such a transition correspond to to harass specific signatures that are not common to
many models, and specific final stages some sign not always but some sign tops

possible to obtain similar both in terms of mediator and dark matter

and from next slide, you can see combined results for both signatures, some sign ups
and single plus missing cutting for flavor validation video and that are on there you
can see exclude exclude imports for

now let's turn to results on the Skyrim Skyrim data. We're also model specific
signatures and common for many models and extends canaris provides a greater variety
of load processes. Very good, in particular a good theoretical

those can be found talk from MSM
and also we can make not model but some generalized interpretation is absolute
discard. In such a generalized interpretation, this two analysis was done
fully fully visible and analysis and signature, okay and signature needs to be
demoed. Okay.
I'll skip
slides on different different limits obtained
in the combined analysis and visibility mode,
and you saw some recent CMS combined posts and just a moment here very interesting

No
final my talk I would like to show these are some very very interesting analysis of
so called double Porter model so called dark Hicks model new scalar design the
notice is if you're instead of standard kicks in this line and by analogy is
discussed earlier, but when you when you when you as a prime, you can see some
analysis and results you can see here Okay, the summary of possible signatures
and you can see that,
for exclusion of some special signatures like flavor violation as prime or as CCS.
Many signatures are not model specific and for some some summary interpretation. What
are interpretations interpretation and my conclusion, why search for Dark Matter
signals is
carried out in different models from very simple to more complex, we are on a signal
of new physics. So far the brainstorming, improvement of physical bus base for
analysis, analysis and expansion of signature started quite first of all by
taking into account channel processes, and you generalize the approach to data
interpretation for SCADA mediator based on Twitch dm per se already in the game and
you can see some in your opinion analysis following clinco for Atlas and CMS and
send for attention.
So much money so, we have one time for one question.
All right, I guess I would like to ask it been what
you know, obviously, we have some direct some dark matter searches and then what
are what is not covered by those dark matter, sir
And that is covered by some of these searches that you talked about with the
you know, heavy heavy object searches or maybe some of those Susi searches. Sorry,
so
I
I can hear you. Hello. Hello, can you hear me? Yes, I can hear you fine. Can you hear
me? Okay? Yes. Okay, so I guess I want to know what what sort of overlaps are there
between some searches for particularly looking for Dark Matter models versus
searches that are looking for other models that have dark matter component? Is there
overlap? Are they complementary with each other?
Uh,
I kind of spent I'm not sure I understand the question. All right, but between
complimentary or intersection studies
You can see the signatures, yes. And many, many signatures are Come on for different
studies. And you need to make only one analysis and maker interpretation in terms
of different set of parameters. But there are some special signatures like, say a
single plus a miss or some
the same signature for specific Skyler. Skyler. mediator, it's a law to support
intimate separation. It's
your signature for very useful for separation, but all our signatures, low
only interpretations. It was your question?
Nope. We can come back to it in the discussion. I mean, I think okay, okay.
Thank you. Okay, so if you could stop sharing please sing louder.
