1 00:00:02,129 --> 00:00:02,819 No, 2 00:00:03,899 --> 00:00:07,079 go ahead. Thank you, apologies for this 3 00:00:07,830 --> 00:00:08,370 small 4 00:00:10,050 --> 00:00:16,170 problem. So, I'm going to give a different perspective as far as the Dark Sector 5 00:00:16,170 --> 00:00:22,170 Sciences is concerned with at. So, the long list of articles perspective, so, as 6 00:00:22,170 --> 00:00:27,870 you know, there are several proposed experiments in this respect and this is a 7 00:00:27,870 --> 00:00:36,000 brief overview of these experiments. So, in So, the lifetime from theory is what 8 00:00:36,180 --> 00:00:41,760 these experiments are trying to explore. So, as you know of the Atlas your mess and 9 00:00:41,760 --> 00:00:47,430 led to be are mostly searching for short lived particles strongly coupled 10 00:00:48,720 --> 00:00:51,420 there and although there is a large 11 00:00:51,750 --> 00:00:52,590 effort in 12 00:00:54,180 --> 00:01:00,630 in our cover also part of the parameter space left for the longest time particles. 13 00:01:00,630 --> 00:01:04,980 There's many aspects that have to be covered. I mean, that was a particle 14 00:01:04,980 --> 00:01:13,920 lifetimes and PSM says, based on a theory span a very wide range of the, as we saw 15 00:01:13,920 --> 00:01:19,890 in previous talks, they may have very low masses, and they involve the divers final 16 00:01:19,890 --> 00:01:25,170 state. So it's necessary to have these dedicated experiments for wrong lift 17 00:01:25,170 --> 00:01:29,610 particles. So I don't have to add match to the dark matter models. There are 18 00:01:30,000 --> 00:01:36,360 excellent talks before me in the session. So just to stress here that of the hidden 19 00:01:36,360 --> 00:01:44,160 sector is precisely a sector where lonely particles exist due to the feebly weakly 20 00:01:45,990 --> 00:01:46,680 interacting 21 00:01:48,150 --> 00:01:54,210 sectors and particles that exist. So the new particles are interacting with 22 00:01:54,210 --> 00:02:03,990 standard model very weakly So this is the outline of my talk two parts. The first 23 00:02:04,020 --> 00:02:10,680 longer part is going to be dedicated to lonely neutral particles that are produced 24 00:02:10,710 --> 00:02:17,640 in proton collisions. And they decay before reaching the detector or in the 25 00:02:17,640 --> 00:02:23,490 detector, and they produce trucks, the trucks, they're what is important from the 26 00:02:23,490 --> 00:02:29,070 point of view of detectors that are there several detectors with different angles 27 00:02:29,070 --> 00:02:35,760 with respect to the beam axis, volume sizes different diesel from a interaction 28 00:02:35,760 --> 00:02:40,980 point is different, etc, the presence of a magnetic field or not. So they can cover 29 00:02:41,400 --> 00:02:51,030 various aspects of these of these case studies that we've talked about, which are 30 00:02:51,060 --> 00:02:57,240 Dark Sector, having three nodes, actual light particles, and I will also just give 31 00:02:57,240 --> 00:03:03,630 them a glimpse of our parliament. Anything supersymmetry these are the experiments 32 00:03:03,630 --> 00:03:07,800 have the two experiments that they will discuss, but there let's remember that 33 00:03:07,800 --> 00:03:14,760 there are other non elite see proposed or running experiments and that also 34 00:03:15,810 --> 00:03:23,010 targeting such scenarios. Another part of the talk is dedicated to mil charged 35 00:03:23,010 --> 00:03:29,190 particles particles that have a fraction charged with respect to the electron. And 36 00:03:29,190 --> 00:03:35,730 I will just highlight two experiments there, Millikan and metal. So, in the long 37 00:03:35,730 --> 00:03:42,420 live neutral particles universe, here is an overview of the early two dedicated 38 00:03:42,660 --> 00:03:51,540 sets. Experiments so in the CMS direction or not social American are going to get 39 00:03:52,650 --> 00:04:02,850 collisions from point five in point A to Z LHB is Served with metal and Codex B and 40 00:04:02,850 --> 00:04:10,770 discover phaser Novus are going to be near Atlas. I know this is a recent proposal 41 00:04:11,430 --> 00:04:20,970 that is expected to be is planned to, to be installed in one of the shafts of 42 00:04:20,970 --> 00:04:30,420 Atlas. And Alex is going to occupy the L three magnet using probably the Alice TPC. 43 00:04:31,950 --> 00:04:39,060 I'm going to a few details on this experiment. So map is the metal apparatus 44 00:04:39,060 --> 00:04:44,340 for penetrating particles. So this is an extension extension of the already 45 00:04:44,340 --> 00:04:51,390 installed and running metal experiment. It's a is made of two parts the longest 46 00:04:51,390 --> 00:04:57,540 particle and the knee charged particles. So then normally if particle is a box 47 00:04:57,540 --> 00:05:05,730 within a box with a simulator strips as you can see, it is located and around 55 48 00:05:05,760 --> 00:05:11,610 meters away from the actual border around a demand of around five degrees with 49 00:05:11,610 --> 00:05:21,090 respect to the axis. And we expect to have around already in round three, it's worth 50 00:05:21,120 --> 00:05:26,280 to say that math three is an expression of math one, which is going to buy the whole 51 00:05:27,030 --> 00:05:33,840 deal to see one gallery. Jim before will give later this day, some more with more 52 00:05:33,930 --> 00:05:40,710 details on that phaser is already approved, is going to be around 500 meters 53 00:05:40,710 --> 00:05:46,740 from the Atlas inflection point is the most forward of this experiment that is 54 00:05:46,740 --> 00:05:47,940 going to start running 55 00:05:48,210 --> 00:05:49,770 after the long shutdown. 56 00:05:51,120 --> 00:05:58,740 What this was saying here is that phaser two is the most sensitive part phase of 57 00:05:58,740 --> 00:06:05,640 this activity. That is going to run for the Haman our city LLC. And that will have 58 00:06:05,820 --> 00:06:12,270 will feature a larger volume with a radius of one meter as opposed to the 10 59 00:06:12,270 --> 00:06:20,010 centimeter cylinder that is expected for this for the run three phase of this 60 00:06:20,010 --> 00:06:28,170 experiment. Again more details in later in the upgrades and future session in the doc 61 00:06:28,170 --> 00:06:37,530 bytes and codecs B. So this is a reliving of the forward proposals. Let's say we go 62 00:06:37,530 --> 00:06:48,180 to the transfers region. So, it's going to be made of six RPC layers at four 63 00:06:48,180 --> 00:06:58,650 centimeter intervals. He has already planning to have a Codex beta demonstrator 64 00:06:58,680 --> 00:07:07,440 smaller party To prove the concept of the experiment and also to measure backgrounds 65 00:07:08,190 --> 00:07:17,550 that are left from the activity sheet that is also going to be installed and 66 00:07:17,550 --> 00:07:22,680 methodical. So the first law is the only of this experiments that is going to be 67 00:07:22,680 --> 00:07:28,170 installed on the surface. So it has no limitations in terms of volume. It is by 68 00:07:28,170 --> 00:07:36,480 far the largest 100,400 square meters with a height of 25 meters. Again, a very nice 69 00:07:37,170 --> 00:07:43,170 demonstration demonstrator that has been installed has run data and the results 70 00:07:43,230 --> 00:07:52,770 have already been published in this link here. And you are invited to check 71 00:07:53,040 --> 00:08:02,460 editorials poster on this experiment. So let's go to there. So I don't have to add 72 00:08:02,460 --> 00:08:07,620 more more to the hidden sector there were excellent dogs before me. And just to 73 00:08:07,980 --> 00:08:14,070 remind you that they will give some results from dark photos peaks and a 74 00:08:14,070 --> 00:08:25,980 tunnels and also actual like articles. So, the minimum dark photon model, so, this up 75 00:08:25,980 --> 00:08:32,670 here you can see an overview of this, of the expectations from these experiments in 76 00:08:32,910 --> 00:08:41,430 the photon, dark photon mass versus versus mixing up that mixing parameter as you can 77 00:08:41,430 --> 00:08:48,420 see, among the VC experiments and latos law has the lower that is their 78 00:08:49,740 --> 00:08:50,910 longer lifetime 79 00:08:53,310 --> 00:09:02,700 reads why phasor do is going to give to have access to other To do heavier 80 00:09:02,700 --> 00:09:12,360 particles, again with the dark Higgs. So, it was mentioned. So, I give these two 81 00:09:12,360 --> 00:09:20,280 plots to show how phaser to the high luminosity extension, and the map is going 82 00:09:20,280 --> 00:09:27,540 to perform when compared with Codex B. Methuselah and other experiments. So here 83 00:09:27,540 --> 00:09:32,940 again you see that latos law is going to have better sensitivity in larger 84 00:09:32,940 --> 00:09:39,750 lifetimes, but it's by their mind that this is going to run afterwards, while the 85 00:09:39,750 --> 00:09:46,350 phaser and not one are going to be able to run are already around three having you 86 00:09:46,350 --> 00:09:53,550 through leptons. So these are two plots on the mixing between the heavy neutrino and 87 00:09:54,030 --> 00:10:04,470 and the Dow neutrino and its mass and here is for the first two bars. durations. So, 88 00:10:04,470 --> 00:10:12,570 you can see also that Alex before latos law can give some good sensitivity in 89 00:10:12,600 --> 00:10:22,650 these companies will just show here also another having a dream scenario or map can 90 00:10:23,100 --> 00:10:32,250 cannot really cover uncovered parameter in having you reluctance, but map to with a 91 00:10:32,280 --> 00:10:39,000 high luminosity extension can indeed cover in the VSA region some parts of the 92 00:10:39,000 --> 00:10:40,080 parameter space 93 00:10:42,270 --> 00:10:43,860 will just last this 94 00:10:46,260 --> 00:10:47,460 the A's and B's 95 00:10:47,490 --> 00:10:51,480 and just to mention the concrete models they are party relating supersymmetry, 96 00:10:51,480 --> 00:10:57,600 where there are already some studies done for this experiments. So, you can see that 97 00:10:57,780 --> 00:11:05,250 also beyond can that Dark Matter sector there is some sensitivity important in our 98 00:11:05,250 --> 00:11:11,580 body regulating that scenario. And this brings me to the second part of my talk, 99 00:11:11,580 --> 00:11:16,980 which is the media talks particles. So, there are two proposals here the Millican 100 00:11:18,480 --> 00:11:23,940 which is expected to be installed the 17 meters away from the CMS interaction 101 00:11:23,970 --> 00:11:32,670 point. There is already a Millikan demonstrator that has done has produced 102 00:11:32,700 --> 00:11:38,850 some results I will show that later. And as the mapping can be detected, which is 103 00:11:38,850 --> 00:11:44,700 going to be installed at the core of the center of the map LLP detector that I 104 00:11:45,390 --> 00:11:50,910 mentioned previously. So, prototype of this has already been installed in 2017. 105 00:11:51,300 --> 00:11:58,950 And the data is being analyzed so far. And these are some results for military 106 00:11:58,980 --> 00:12:04,590 particles show this One dark photon scenario with garbage the massive dark 107 00:12:04,590 --> 00:12:13,860 fermion really charged sighs So, all these trillion and lower mass particles 108 00:12:14,970 --> 00:12:22,680 production is being consumed consider as you can see that already the Millican 109 00:12:22,860 --> 00:12:28,380 demonstrator has covered some part of the parameters phases here are the 110 00:12:28,380 --> 00:12:38,910 expectations from a medical on top and map and to be below in this context. So, while 111 00:12:38,910 --> 00:12:42,690 there is a value added from these experiments as well in the scope 112 00:12:43,830 --> 00:12:44,910 and just 113 00:12:45,209 --> 00:12:51,329 having a trainer with large EDM, so, dark photon scenarios are not the only ones 114 00:12:51,329 --> 00:12:52,289 that have 115 00:12:53,520 --> 00:12:56,370 that may have sensitivity 116 00:12:57,270 --> 00:13:04,470 may give sensitivity for this formulation And mapping to be the anomalously large 117 00:13:04,500 --> 00:13:08,460 EDM of having neutrinos can also be 118 00:13:09,809 --> 00:13:10,589 used, 119 00:13:11,069 --> 00:13:17,159 for instance, as shown in this plot for map entropy to cover part of the parameter 120 00:13:17,159 --> 00:13:25,409 space. So, this is another case and this brings me to my summary. So there is an 121 00:13:25,409 --> 00:13:30,059 ever increasing interest in longest particle searches and you're invited to 122 00:13:30,089 --> 00:13:38,609 visit this. This links here. There are new ideas for this complimentary to the large 123 00:13:39,029 --> 00:13:42,929 experiments, proposals. They're in various 124 00:13:45,570 --> 00:13:47,730 construction preparation phases, 125 00:13:48,150 --> 00:13:54,930 and they are already some demonstrators that have run. I have proven the concept 126 00:13:54,930 --> 00:14:01,980 of these proposals and they give a different perspective. Long glider or loud 127 00:14:01,980 --> 00:14:03,750 lifetime or the Dark Sector 128 00:14:04,770 --> 00:14:08,670 in the early two, round three and beyond. Thank you. 129 00:14:12,330 --> 00:14:17,250 Thank you very much lightning a huge number of different proposals and 130 00:14:17,250 --> 00:14:23,220 happening experiments. Very, very useful. We can take questions now. If anyone has 131 00:14:23,610 --> 00:14:24,180 something 132 00:14:35,610 --> 00:14:37,500 this is maybe a little unfair if 133 00:14:39,060 --> 00:14:40,980 you were explicitly alleged. 134 00:14:42,840 --> 00:14:49,290 But I found your summary of these these proposals here useful and I track of the 135 00:14:49,290 --> 00:14:52,950 status of shit on there. Do you know 136 00:14:54,120 --> 00:15:00,750 the ship? Yeah, you're breaking up the ship. Yes. 137 00:15:02,190 --> 00:15:09,420 Well, I I couldn't cover also this but there is a significant progress there 138 00:15:09,480 --> 00:15:17,310 actually was a very interesting talk on the SMD detector, which is actually a 139 00:15:17,310 --> 00:15:26,760 neutrino detector for from this ship. So this was presented this week in the LLC 140 00:15:26,760 --> 00:15:27,540 LLP 141 00:15:29,940 --> 00:15:34,530 workshop So, so you can have a look there. 142 00:15:36,390 --> 00:15:40,200 We'll do Thanks a lot. Yes, it's been too bad for the same weekend. 143 00:15:41,940 --> 00:15:46,380 Well, on the other side of that gate, these results are very fresh. Let's see 144 00:15:58,260 --> 00:16:03,300 if there were any more questions For a facility Go ahead, but we also actually 145 00:16:03,300 --> 00:16:08,700 have a little extra time now. And if you have questions for any lists or discussion 146 00:16:08,700 --> 00:16:12,750 points to bring up while we have the experts in the room, then please feel 147 00:16:12,750 --> 00:16:20,070 free. And just in case you can have around 30 attendee lines, so it's reasonable 148 00:16:20,070 --> 00:16:23,760 number to have a little discussion if any points you'd like to bring up. 149 00:16:44,940 --> 00:16:49,440 Okay, then it seems as though everyone is satisfied, in which case maybe we should 150 00:16:49,440 --> 00:16:54,660 close the session and you have a slightly extended coffee break. The next VSM 151 00:16:54,780 --> 00:17:00,990 session is joint with PSM one and we'll start at 215 European Time So hopefully 152 00:17:00,990 --> 00:17:04,440 see a lot of you there. And thanks again for connecting today and thanks to all of 153 00:17:04,440 --> 00:17:05,040 our speakers for
