1 00:00:01,979 --> 00:00:06,329 minutes left etc. Okay, so you can start when you want. 2 00:00:06,869 --> 00:00:10,949 Okay, thank you. Okay so I want to thank the organizer to give me the chance to 3 00:00:11,099 --> 00:00:15,779 introduce some latest work from Atlas and CMS collaboration about this topic the 4 00:00:15,779 --> 00:00:21,779 typos and resna search and the quick searches Okay, so since they actually see 5 00:00:21,779 --> 00:00:26,969 has reached a new Manasa t are 114 volts and dopa so more and more nurses have 6 00:00:26,969 --> 00:00:31,889 reached high sensitivity and precision. So it's impossible to just include all the 7 00:00:31,949 --> 00:00:37,019 all this nice works in just one talk. So today I will just focus on the most recent 8 00:00:37,019 --> 00:00:41,729 results from the SMC Ms. So I'm going to show six and assets about a diverse and 9 00:00:41,729 --> 00:00:48,029 resna search and three for the vo Q. Okay, so we first go to the STI boson resonance 10 00:00:48,029 --> 00:00:52,319 search. So as we all know, the standard model has successfully described the most 11 00:00:52,349 --> 00:00:56,939 of the phenomenon observed in the high energy physics experiments. Still there 12 00:00:56,939 --> 00:01:01,079 essential comments indicate some kind of new physics such as The hierarchy problem 13 00:01:01,079 --> 00:01:06,419 the invocation of the gravity or the document dark energy. So many bsm theories 14 00:01:06,419 --> 00:01:11,189 has been proposed and many of them have predicted new heavy resonances. For 15 00:01:11,189 --> 00:01:16,769 example, the spins are radiant spin one that is a prime w prime or the spin to 16 00:01:16,769 --> 00:01:22,799 this kaluza clang Graviton or the Gk So, add the TV scale they will decay into a 17 00:01:22,799 --> 00:01:28,859 pair of standard model buttons, I mean the W x or gamma. So the search for diverse 18 00:01:28,889 --> 00:01:34,829 resonance is a good prop to the beyond model physics. Okay, so then we start with 19 00:01:34,829 --> 00:01:40,139 this search for the vs vs gnosis in the hydronic find the states for methods. So 20 00:01:40,139 --> 00:01:45,779 this is a process with a pair of W or is that bosons and Higgs boson and the W and 21 00:01:45,779 --> 00:01:51,359 or is that the case into our pair of the quarks and Higgs to our pair peacocks. So 22 00:01:51,359 --> 00:01:59,549 the hvt model is taken as the signal here and so since the Ws s highly boosted so 23 00:01:59,549 --> 00:02:05,069 that can production will be grouped constructed into two large budgets and 24 00:02:05,069 --> 00:02:10,019 also to techno signatures from the Boston decay. They also used jet substructures 25 00:02:10,019 --> 00:02:15,179 information such as the jet master detail arrival and detractors to better 26 00:02:15,179 --> 00:02:20,939 discriminate the signal jets. And then the dye. devera Massey still used to have four 27 00:02:20,939 --> 00:02:26,159 Ps and particle and the background Manningham from the QC D multiple Multijet 28 00:02:26,159 --> 00:02:32,339 processes. And since there is no access from the senemo prediction the limit upper 29 00:02:32,339 --> 00:02:35,939 limit of the production cross section times the branch ratio against the 30 00:02:35,939 --> 00:02:40,919 daydreamer masks are set with the ecliptic with the exclusion of certain mass ranges 31 00:02:40,919 --> 00:02:46,409 for the w prime z prime particles. And this result can also be translated into 32 00:02:46,409 --> 00:02:53,849 exclusions in the ght f play, where the gf gq GH are the couplings of W and z prime 33 00:02:53,849 --> 00:02:58,889 to the fermions quarks and x and a GQ is taken to be equal to gf. In this scenario, 34 00:02:59,999 --> 00:03:03,539 The next analysis this this multi dimensional search for the diverse 35 00:03:03,539 --> 00:03:09,419 resonances in the United States from CMS. And this analysis such as for for COC 36 00:03:09,419 --> 00:03:15,899 final states that merged into two large artists and the prime w prime and the GTK 37 00:03:15,899 --> 00:03:22,769 are taken as the possible signal candidates here. So, the jet mass and this 38 00:03:22,769 --> 00:03:29,879 jet aim subject and as ratio to one are used to tack the signatures and then the 39 00:03:29,879 --> 00:03:35,819 event is divided into two purity categories. Now, as the hpsp and hvlp are 40 00:03:35,819 --> 00:03:41,459 defined based on the top two y values and adorns dominant backgrounds is this acuity 41 00:03:41,459 --> 00:03:45,779 manager the process and the observation matches with the background prediction 42 00:03:45,779 --> 00:03:49,799 Well, so, then the upper limit of the cross section against the requirements is 43 00:03:49,799 --> 00:03:56,249 set and the exclusion is also also set on the w prime minister prime particles. And 44 00:03:56,249 --> 00:04:01,529 thanks to the group in the implementation of the multimedia dimensional fit the 45 00:04:01,529 --> 00:04:08,009 sensitivity significantly improved with respect to the reverse such as the next 46 00:04:08,009 --> 00:04:15,419 search is the statics to bbbbbb production from found from Atlas. So, this ns is such 47 00:04:15,419 --> 00:04:22,199 as for both resident and another's non production mode via the vpf process. So, 48 00:04:22,199 --> 00:04:27,869 but today we will only focus on this resident production mode. And the since 49 00:04:27,869 --> 00:04:32,489 there are four peacocks, the dye experience assigned from them with the 50 00:04:32,489 --> 00:04:37,619 minimal DHH variable that's defined here. And 51 00:04:39,630 --> 00:04:43,740 also multiple variables has been developed and developed to have to suppress the 52 00:04:43,740 --> 00:04:48,810 backgrounds that mainly come from the multi jet and the teapot process and 53 00:04:48,810 --> 00:04:57,420 spectrum of the post the feet and for B distribution here on the bottom left shows 54 00:04:57,420 --> 00:05:01,740 a good agreement between the data and the Standing Order predictions So then the 55 00:05:02,400 --> 00:05:08,040 limits of the signal set. So both broad and narrow resnet signal scenarios are 56 00:05:08,040 --> 00:05:17,400 considered and and they are shown on the on the right. Okay, so the next analysis 57 00:05:17,400 --> 00:05:21,690 this then this new did this have a resident that came to the hex pairing the 58 00:05:21,690 --> 00:05:28,680 BBQ Keanu van states from CMS. And in this NSS there is a presence of a large rpp jet 59 00:05:29,010 --> 00:05:34,080 coming from one hex and the other larger KPJ coming from the W TK, and the other w 60 00:05:34,080 --> 00:05:39,630 from the Higgs would decay that tonically and to get a piece out of the neutrino, we 61 00:05:39,630 --> 00:05:47,280 need to use the left and the the we use need to use the left and the qq jet and 62 00:05:47,280 --> 00:05:54,180 the Higgs mass to solve the corresponding second order equation. And for the signal 63 00:05:54,180 --> 00:06:02,790 models here considered here we are we were using the radian and the Gk Also there are 64 00:06:02,790 --> 00:06:07,230 some Angular cuts applied to the left hand side VB Q, just to make sure that you 65 00:06:07,230 --> 00:06:13,860 Higgs back to back, and main background here, TT bar, Martin jet and Ws jet. The 66 00:06:13,860 --> 00:06:19,440 events are then divided into 12 categories that are summarized in this table based on 67 00:06:19,440 --> 00:06:23,910 the left server and the Jeff substructures, then the BB jet mass and 68 00:06:24,060 --> 00:06:27,630 the die hex resna mass in all categories that fits in Montana State to keep the 69 00:06:27,630 --> 00:06:33,750 limits on the radio and the GTK. This is also the first result from CMS in this in 70 00:06:33,750 --> 00:06:40,560 this channel. And next slide is the search for the heavy resonance, heavy dipole 71 00:06:40,590 --> 00:06:46,440 resonance in the semi electronic states from Atlas. So this analysis covers a wide 72 00:06:46,440 --> 00:06:51,360 range of production and decay modes. So the production mode can be the GTF Julian 73 00:06:51,360 --> 00:06:59,370 or the Vf and one of the bosses can decay into it can decay into 01 or two leptons, 74 00:06:59,550 --> 00:07:04,140 and the other Somebody care hydroponically resulting in either emerged or results 75 00:07:04,140 --> 00:07:11,580 jets the titty bar definition and Ws jet and main backgrounds here but with 76 00:07:11,580 --> 00:07:17,550 different importance in different categories and so, the simpler models 77 00:07:17,550 --> 00:07:25,290 including the radiant the prime the prime and then also the Gk. So, then then the 78 00:07:25,290 --> 00:07:28,980 environment of the system is taken as the discriminant rival except for in the zero 79 00:07:28,980 --> 00:07:33,000 lepton category where it is impossible to review the very mass. So, then the 80 00:07:33,000 --> 00:07:39,600 transverse mass is adopted as the discriminant as So, here's the result of 81 00:07:39,600 --> 00:07:45,480 the upper limits of the different signal models and different production modes. So, 82 00:07:45,480 --> 00:07:49,890 through the gf and to try and process the lower limit on the possible masses for 83 00:07:49,890 --> 00:07:54,960 radian w prime z prime and the Graviton extracted and for the BBF process, 84 00:07:54,960 --> 00:07:56,760 domestic medical grafting is obtained. 85 00:07:58,260 --> 00:08:02,160 Okay, so, the next analysis This stage addressed in a search with the pickers 86 00:08:02,220 --> 00:08:06,750 with a weak supervision from Fs. So, this is a very interesting as it that uses a 87 00:08:06,750 --> 00:08:10,830 machine learning anomaly detection procedure that does not rely on any signal 88 00:08:10,830 --> 00:08:15,510 model. And this is also actually not only a diversity search things the two GS can 89 00:08:15,510 --> 00:08:21,120 also come from other sources like the Taos or quarks and even the bsm particles. And 90 00:08:21,120 --> 00:08:26,430 the core of this and as is the technique of a classification without labels, also 91 00:08:26,430 --> 00:08:31,500 known as the koala. And unlike the supervised learning using labeled samples 92 00:08:31,500 --> 00:08:36,330 based on simulation called ice is a fully data driven method. The classifier is 93 00:08:36,330 --> 00:08:41,700 trained using to mixed samples that suggested statistically identical aside 94 00:08:41,700 --> 00:08:47,190 from different class proportion and then to implement this color in the in the data 95 00:08:47,190 --> 00:08:51,270 resna search the mjg spectrum will be reconstructed and then divided into 96 00:08:51,270 --> 00:08:56,070 multiple things and each as a signal region. Then the two neighboring beings 97 00:08:56,070 --> 00:09:01,620 are called as the US called the sideband regions Then the region the sidebar 98 00:09:01,620 --> 00:09:09,210 regions, just the two mixed samples that are required by color. And then a network 99 00:09:09,210 --> 00:09:13,830 is trying to distinguish the difference of the mjg shape between the given signal 100 00:09:13,830 --> 00:09:17,820 region and the two neighboring sidebar regions using the methods of the Jets as 101 00:09:17,820 --> 00:09:22,980 the input features. If it does not, if it does find the anomaly in the signal region 102 00:09:22,980 --> 00:09:27,330 the signal bump will be enhanced. Otherwise that empty spot on with spectrum 103 00:09:27,330 --> 00:09:32,640 will remain smooth and compare with the condition the bsm search quality is 104 00:09:32,640 --> 00:09:37,740 sensitive to a plenty of signals in instead of just one or a few signals. And 105 00:09:37,740 --> 00:09:43,200 it's also a smart way doing 3d bump count that avoid a lot of trial factors from the 106 00:09:43,200 --> 00:09:50,160 looks out looks as well effect and to stabilize the training procedure some pre 107 00:09:50,160 --> 00:09:57,540 selection made to the to the to the objects and also the MG m one m two it 108 00:09:57,540 --> 00:10:02,670 correlated before the input to the network and then the input samples are separated 109 00:10:02,670 --> 00:10:09,120 into five slices for training cross validation and test and validation of the 110 00:10:09,120 --> 00:10:13,020 network performance you can see the plots on the right here the to the efficient map 111 00:10:13,200 --> 00:10:18,030 with or without a signal injection is shown. And the low efficiency actually 112 00:10:18,090 --> 00:10:23,580 stands for high a score. So, we can see clearly here with the region with the 113 00:10:23,580 --> 00:10:31,650 highest score a suggested region that we injected signal. And so, although this 114 00:10:31,650 --> 00:10:36,000 method is fully data driven and model independent, we can also do a model 115 00:10:36,000 --> 00:10:41,850 dependent feeds for specific signal model to extract the its limit to do such a 116 00:10:41,850 --> 00:10:45,960 thing when the network would be trained with a signal injected and selection is 117 00:10:45,960 --> 00:10:50,910 then applied based on the training result. And then the usual the usual limit setting 118 00:10:50,910 --> 00:10:56,430 procedure is carried out to get the get the results here. And as shown here, this 119 00:10:56,430 --> 00:11:02,670 results of more sensitive data inclusive digest searches And they extend and extend 120 00:11:02,700 --> 00:11:07,410 the coverage of the all hydronic adaptive searches to regions five from from the 121 00:11:07,410 --> 00:11:13,890 Standard Model masses. And since this now we're just we're only doing the two 122 00:11:13,890 --> 00:11:18,930 dimensional two dimensional search where there's a great potential even extend this 123 00:11:18,930 --> 00:11:25,260 method to a bet to get some better result. Okay, so then we can move to the second 124 00:11:25,260 --> 00:11:30,060 part of my talk, which is the backlight clock search. So the vector clocks heavy 125 00:11:30,060 --> 00:11:34,860 non Cairo clocks with a symmetric left and right handed couplings to the Standard 126 00:11:34,860 --> 00:11:39,270 Model particles and the different from the Standard Model quarks. The vector cost 127 00:11:39,270 --> 00:11:43,050 does not obtain mass through the Higgs mechanism, but through a neutron sector 128 00:11:43,050 --> 00:11:49,350 confinement, and the via Q's are predicted in many mbsr theories. And it could have 129 00:11:49,380 --> 00:11:53,370 could have a role in stabilizing the Higgs boson mass and does have a potential 130 00:11:53,370 --> 00:11:59,970 solution to the hierarchy problem. Vector like quarks can be the simplest place or 131 00:12:00,000 --> 00:12:05,370 tripolis and decays into a standard model top or bottom class in association with w 132 00:12:05,370 --> 00:12:10,500 Zed or Higgs boson. And the results shown today are focused on the single production 133 00:12:10,500 --> 00:12:15,450 mode. So compared with the production modes, the single practice production mode 134 00:12:15,450 --> 00:12:21,960 is more sensitive to prop the couplings rather than rather than setting limits on 135 00:12:21,960 --> 00:12:23,130 the big masses. 136 00:12:24,570 --> 00:12:28,620 Okay, then the first American search is this search for the single production as 137 00:12:28,620 --> 00:12:34,770 VOD can into w bottom from Atlas. So this person has a signature by electronic 138 00:12:34,770 --> 00:12:40,500 decayed W and digit in association with a surgeon with former jet and a low energy 139 00:12:40,590 --> 00:12:46,050 DJ that often fall out of their caste acceptance. So then, we have this missing 140 00:12:46,050 --> 00:12:50,910 ticket up to 120 gV, the process of escaping neutrino and some Angular cause 141 00:12:50,910 --> 00:12:56,520 to have to suppress the backgrounds and the interference between the MTP for the 142 00:12:56,550 --> 00:13:01,020 work of signal protection the Standard Model process also considered The next to 143 00:13:01,020 --> 00:13:04,530 the you know the cross section corrected with this interference take into account 144 00:13:05,610 --> 00:13:10,830 and so the main Bronk backgrounds are coming from the TD Bosingwa top and the W 145 00:13:10,830 --> 00:13:14,550 Jade process the data is found to be consistent with the background prediction 146 00:13:15,450 --> 00:13:21,570 and the limit set with the re weighting factors of the interference effect applied 147 00:13:22,080 --> 00:13:28,620 and for the for the B why why the result is competitive with the indirect rate 148 00:13:28,620 --> 00:13:35,550 constraint in the range from 100 to 1350 G and x axis is the search for a large 149 00:13:35,550 --> 00:13:41,400 miscibility with one stop Hawk from SS. So, in this search the vo vo Q is one of 150 00:13:41,400 --> 00:13:46,200 the signal candidates that a vector like peacock decays into a dead person and top 151 00:13:46,200 --> 00:13:50,940 Quark and then that decay into a pair of neutrinos which gives a large miscibility 152 00:13:51,210 --> 00:13:56,040 and the top decays into multiple jets and conduct culminated into one larger budget 153 00:13:56,460 --> 00:13:59,670 and find the discriminant if discriminant will be a transverse mass of the missing 154 00:13:59,670 --> 00:14:06,060 at JIT the main backgrounds are TT bar single top WGS and depthless yet and no 155 00:14:06,060 --> 00:14:13,050 significant excess before above this enomoto expected is found in the limit of 156 00:14:13,050 --> 00:14:16,890 the cross section time rented ratio set with a narrow with approximate a 157 00:14:16,950 --> 00:14:23,130 approximation used. Okay next analysis this electroweak production of backtrack t 158 00:14:23,130 --> 00:14:30,570 cocking fully hydronic states in the states from Sam s, and in this and his the 159 00:14:30,570 --> 00:14:36,030 vector like t kwaku decays into a top that pair or a top Hicks pair where the vector 160 00:14:36,030 --> 00:14:40,290 Boston decays into your pair frequency box and the top Quark decays or hydroponically 161 00:14:41,040 --> 00:14:47,130 for the production of the vector it can either come from wb fusion or Zed t 162 00:14:47,130 --> 00:14:52,020 fusion, and gives different types of outgoing quarks and then search is carried 163 00:14:52,020 --> 00:14:56,820 out into different mass ranges. The low mass range search looks for five jet 164 00:14:56,820 --> 00:15:03,930 resonances with at least three p jets and high Astra wrenches search looks for looks 165 00:15:03,930 --> 00:15:09,900 for the environment of the two larger jets and the plot here shows the background the 166 00:15:09,900 --> 00:15:15,720 modeling the signal regions for hollow and high masses for t that and TX respectively 167 00:15:16,110 --> 00:15:21,030 and the dominant background here at multi jet and the Tiki Bar again this there's no 168 00:15:21,030 --> 00:15:26,760 significant access of data above the standard of prediction. And then the 169 00:15:26,760 --> 00:15:31,920 limits are set on the cross section times the branching ratio for different Messner 170 00:15:31,920 --> 00:15:37,140 with and the partial here actually are combined limits for the TNT that and also 171 00:15:37,140 --> 00:15:40,290 the loan master and then high master enjoyed the best estimate expectation 172 00:15:40,320 --> 00:15:49,080 expected sensitivity. And for the TMS below one TV the modal with with bottom 173 00:15:49,080 --> 00:15:55,620 Kaka strongly constraint okay then oh can finally go to summary. So fortunately 174 00:15:55,620 --> 00:15:59,520 there still no have this for the beyond Standard Model physics yet. But we have 175 00:15:59,520 --> 00:16:04,560 set them at for multiple theory models of diverse resonance and the vo Q, which is 176 00:16:04,560 --> 00:16:08,490 the method the rest of the methods higher, and there's already some combination 177 00:16:08,490 --> 00:16:14,460 efforts made that to give that can give a bigger picture for the type of devil 178 00:16:14,460 --> 00:16:18,750 searches. And we have also developed some new techniques to develop to better 179 00:16:18,750 --> 00:16:24,630 distinguish the, the W Zed or Higgs from Stanmore, the backgrounds and we believe 180 00:16:24,630 --> 00:16:28,590 there will be much more to come with more analysis correct scrutinizing the full run 181 00:16:28,590 --> 00:16:30,480 to data. Okay, thank you very much. 182 00:16:32,880 --> 00:16:33,960 Thank you very much. 183 00:16:35,820 --> 00:16:37,770 Other questions? 184 00:16:48,210 --> 00:16:57,930 Okay, I may have one So, about Victor loquats. I seem to remember that at the 185 00:16:57,930 --> 00:17:05,400 beginning of friend to say There were some kind of incompatibilities between the 186 00:17:05,400 --> 00:17:10,050 Atlas and CMS setup on the way like the generic tools that we use. And so, we 187 00:17:10,050 --> 00:17:16,110 couldn't put for instance side by side, the single new production results at least 188 00:17:16,110 --> 00:17:22,260 not as easy as that to you know, if now, when the results that are produced or that 189 00:17:22,260 --> 00:17:26,670 are being produced or that will be produced, these things will be fixed or 190 00:17:26,670 --> 00:17:27,180 not. 191 00:17:28,740 --> 00:17:31,200 Or I don't know that sorry. 192 00:17:32,910 --> 00:17:33,480 No problem. 193 00:17:36,780 --> 00:17:43,680 Then. So, another question that comes from when we have all these searches that have 194 00:17:43,680 --> 00:17:49,140 final status are basically the same as the one of the terminating background at one 195 00:17:49,140 --> 00:17:54,690 level. So I'm wondering are interferences Are there any interference effect that has 196 00:17:54,690 --> 00:17:58,740 to be taken into account and collected in these searches so I think for instance, 197 00:17:58,740 --> 00:18:03,690 here on the screen Have your two that's one, but I think also for at some point to 198 00:18:03,690 --> 00:18:13,500 die, but I think the the final thing with to these two quotes slept on neutrino 199 00:18:14,070 --> 00:18:21,900 which is basically what one could expect from Chiba is the interference basically 200 00:18:21,900 --> 00:18:22,920 negligible. Yeah. 201 00:18:24,000 --> 00:18:28,770 So, so this one the single production reactor is the only one that I see the 202 00:18:28,770 --> 00:18:33,120 mentioned this in their paper, so I guess for the others, this should be negligible. 203 00:18:37,590 --> 00:18:38,040 Okay. 204 00:18:44,400 --> 00:18:45,360 Okay, interesting. 205 00:18:47,820 --> 00:18:50,850 Okay. Are there any further question?
