No,
go ahead. Thank you, apologies for this
small
problem. So, I'm going to give a different perspective as far as the Dark Sector
Sciences is concerned with at. So, the long list of articles perspective, so, as
you know, there are several proposed experiments in this respect and this is a
brief overview of these experiments. So, in So, the lifetime from theory is what
these experiments are trying to explore. So, as you know of the Atlas your mess and
led to be are mostly searching for short lived particles strongly coupled
there and although there is a large
effort in
in our cover also part of the parameter space left for the longest time particles.
There's many aspects that have to be covered. I mean, that was a particle
lifetimes and PSM says, based on a theory span a very wide range of the, as we saw
in previous talks, they may have very low masses, and they involve the divers final
state. So it's necessary to have these dedicated experiments for wrong lift
particles. So I don't have to add match to the dark matter models. There are
excellent talks before me in the session. So just to stress here that of the hidden
sector is precisely a sector where lonely particles exist due to the feebly weakly
interacting
sectors and particles that exist. So the new particles are interacting with
standard model very weakly So this is the outline of my talk two parts. The first
longer part is going to be dedicated to lonely neutral particles that are produced
in proton collisions. And they decay before reaching the detector or in the
detector, and they produce trucks, the trucks, they're what is important from the
point of view of detectors that are there several detectors with different angles
with respect to the beam axis, volume sizes different diesel from a interaction
point is different, etc, the presence of a magnetic field or not. So they can cover
various aspects of these of these case studies that we've talked about, which are
Dark Sector, having three nodes, actual light particles, and I will also just give
them a glimpse of our parliament. Anything supersymmetry these are the experiments
have the two experiments that they will discuss, but there let's remember that
there are other non elite see proposed or running experiments and that also
targeting such scenarios. Another part of the talk is dedicated to mil charged
particles particles that have a fraction charged with respect to the electron. And
I will just highlight two experiments there, Millikan and metal. So, in the long
live neutral particles universe, here is an overview of the early two dedicated
sets. Experiments so in the CMS direction or not social American are going to get
collisions from point five in point A to Z LHB is Served with metal and Codex B and
discover phaser Novus are going to be near Atlas. I know this is a recent proposal
that is expected to be is planned to, to be installed in one of the shafts of
Atlas. And Alex is going to occupy the L three magnet using probably the Alice TPC.
I'm going to a few details on this experiment. So map is the metal apparatus
for penetrating particles. So this is an extension extension of the already
installed and running metal experiment. It's a is made of two parts the longest
particle and the knee charged particles. So then normally if particle is a box
within a box with a simulator strips as you can see, it is located and around 55
meters away from the actual border around a demand of around five degrees with
respect to the axis. And we expect to have around already in round three, it's worth
to say that math three is an expression of math one, which is going to buy the whole
deal to see one gallery. Jim before will give later this day, some more with more
details on that phaser is already approved, is going to be around 500 meters
from the Atlas inflection point is the most forward of this experiment that is
going to start running
after the long shutdown.
What this was saying here is that phaser two is the most sensitive part phase of
this activity. That is going to run for the Haman our city LLC. And that will have
will feature a larger volume with a radius of one meter as opposed to the 10
centimeter cylinder that is expected for this for the run three phase of this
experiment. Again more details in later in the upgrades and future session in the doc
bytes and codecs B. So this is a reliving of the forward proposals. Let's say we go
to the transfers region. So, it's going to be made of six RPC layers at four
centimeter intervals. He has already planning to have a Codex beta demonstrator
smaller party To prove the concept of the experiment and also to measure backgrounds
that are left from the activity sheet that is also going to be installed and
methodical. So the first law is the only of this experiments that is going to be
installed on the surface. So it has no limitations in terms of volume. It is by
far the largest 100,400 square meters with a height of 25 meters. Again, a very nice
demonstration demonstrator that has been installed has run data and the results
have already been published in this link here. And you are invited to check
editorials poster on this experiment. So let's go to there. So I don't have to add
more more to the hidden sector there were excellent dogs before me. And just to
remind you that they will give some results from dark photos peaks and a
tunnels and also actual like articles. So, the minimum dark photon model, so, this up
here you can see an overview of this, of the expectations from these experiments in
the photon, dark photon mass versus versus mixing up that mixing parameter as you can
see, among the VC experiments and latos law has the lower that is their
longer lifetime
reads why phasor do is going to give to have access to other To do heavier
particles, again with the dark Higgs. So, it was mentioned. So, I give these two
plots to show how phaser to the high luminosity extension, and the map is going
to perform when compared with Codex B. Methuselah and other experiments. So here
again you see that latos law is going to have better sensitivity in larger
lifetimes, but it's by their mind that this is going to run afterwards, while the
phaser and not one are going to be able to run are already around three having you
through leptons. So these are two plots on the mixing between the heavy neutrino and
and the Dow neutrino and its mass and here is for the first two bars. durations. So,
you can see also that Alex before latos law can give some good sensitivity in
these companies will just show here also another having a dream scenario or map can
cannot really cover uncovered parameter in having you reluctance, but map to with a
high luminosity extension can indeed cover in the VSA region some parts of the
parameter space
will just last this
the A's and B's
and just to mention the concrete models they are party relating supersymmetry,
where there are already some studies done for this experiments. So, you can see that
also beyond can that Dark Matter sector there is some sensitivity important in our
body regulating that scenario. And this brings me to the second part of my talk,
which is the media talks particles. So, there are two proposals here the Millican
which is expected to be installed the 17 meters away from the CMS interaction
point. There is already a Millikan demonstrator that has done has produced
some results I will show that later. And as the mapping can be detected, which is
going to be installed at the core of the center of the map LLP detector that I
mentioned previously. So, prototype of this has already been installed in 2017.
And the data is being analyzed so far. And these are some results for military
particles show this One dark photon scenario with garbage the massive dark
fermion really charged sighs So, all these trillion and lower mass particles
production is being consumed consider as you can see that already the Millican
demonstrator has covered some part of the parameters phases here are the
expectations from a medical on top and map and to be below in this context. So, while
there is a value added from these experiments as well in the scope
and just
having a trainer with large EDM, so, dark photon scenarios are not the only ones
that have
that may have sensitivity
may give sensitivity for this formulation And mapping to be the anomalously large
EDM of having neutrinos can also be
used,
for instance, as shown in this plot for map entropy to cover part of the parameter
space. So, this is another case and this brings me to my summary. So there is an
ever increasing interest in longest particle searches and you're invited to
visit this. This links here. There are new ideas for this complimentary to the large
experiments, proposals. They're in various
construction preparation phases,
and they are already some demonstrators that have run. I have proven the concept
of these proposals and they give a different perspective. Long glider or loud
lifetime or the Dark Sector
in the early two, round three and beyond. Thank you.
Thank you very much lightning a huge number of different proposals and
happening experiments. Very, very useful. We can take questions now. If anyone has
something
this is maybe a little unfair if
you were explicitly alleged.
But I found your summary of these these proposals here useful and I track of the
status of shit on there. Do you know
the ship? Yeah, you're breaking up the ship. Yes.
Well, I I couldn't cover also this but there is a significant progress there
actually was a very interesting talk on the SMD detector, which is actually a
neutrino detector for from this ship. So this was presented this week in the LLC
LLP
workshop So, so you can have a look there.
We'll do Thanks a lot. Yes, it's been too bad for the same weekend.
Well, on the other side of that gate, these results are very fresh. Let's see
if there were any more questions For a facility Go ahead, but we also actually
have a little extra time now. And if you have questions for any lists or discussion
points to bring up while we have the experts in the room, then please feel
free. And just in case you can have around 30 attendee lines, so it's reasonable
number to have a little discussion if any points you'd like to bring up.
Okay, then it seems as though everyone is satisfied, in which case maybe we should
close the session and you have a slightly extended coffee break. The next VSM
session is joint with PSM one and we'll start at 215 European Time So hopefully
see a lot of you there. And thanks again for connecting today and thanks to all of
our speakers for
