1 00:00:02,040 --> 00:00:06,240 Results from from CMS. So please go ahead when you're ready. Good, thank you. 2 00:00:07,319 --> 00:00:12,089 Yes, I'll give you an overview of recent results in Power BI probes from from CMS. 3 00:00:14,009 --> 00:00:18,689 So, these give access to hospital processes and they are produced early in 4 00:00:18,689 --> 00:00:21,809 the collisions with the can be sensitive to the medium evolution. 5 00:00:23,580 --> 00:00:28,680 There will be more categories of posts and during this 6 00:00:30,060 --> 00:00:38,760 say, family of help hopes, liquid bosons and high energy photons. When Yeah, that's 7 00:00:38,760 --> 00:00:45,420 type e d happens so I won't have time to cover within here. We focus on jet related 8 00:00:45,420 --> 00:00:52,200 results say for heavy flavor on California. I would point you to to talk 9 00:00:52,200 --> 00:00:56,640 on Wednesday and then for initial state on liquid hopes that will be on Friday. So we 10 00:00:56,640 --> 00:00:58,530 really focus on jets here. 11 00:01:00,359 --> 00:01:05,189 So let me start with the first result that we'll be talking about, which is a 12 00:01:05,189 --> 00:01:11,489 measurement of charge in p&l equations. So, the idea here is to 13 00:01:12,599 --> 00:01:18,179 to have to extract Quark and given fractions using a charge in ppm outlet. 14 00:01:18,629 --> 00:01:22,259 So, the charge is defined using this equation here. 15 00:01:24,510 --> 00:01:25,530 So, we 16 00:01:30,150 --> 00:01:38,310 have the different tax associated to the to the jet. And you see similar parameters 17 00:01:38,340 --> 00:01:42,090 with the Kappa and there is also a threshold under 18 00:01:43,170 --> 00:01:49,650 the effects which are included in this in this observable. So, this is the first 19 00:01:50,220 --> 00:01:52,410 charge measurement in in collisions, 20 00:01:53,430 --> 00:01:56,730 again exploiting the correlation between the bottom church and the reconstructed 21 00:01:56,730 --> 00:01:59,970 church church, as we see here in this plot 22 00:02:00,000 --> 00:02:05,070 So this is showing the data for PP on the left and the difference in colleges for a 23 00:02:05,070 --> 00:02:10,380 lead. And if we look at the templates, which are built using PCR, we see that for 24 00:02:10,380 --> 00:02:15,810 grants, the template is more or less centered on zero. And then for quarks, we 25 00:02:15,810 --> 00:02:23,130 expect a larger, well positive charge. So on the voyage, and then, and then he gets 26 00:02:23,400 --> 00:02:24,810 discharged from the voyage for 27 00:02:28,230 --> 00:02:33,960 you see that this template feeds give a good description of the data. So this is 28 00:02:33,960 --> 00:02:39,300 after unfolding for the decoy effects. And then if we look at the results from these 29 00:02:39,300 --> 00:02:44,760 templates, we see that so again, these are the same process with the different 30 00:02:44,760 --> 00:02:50,580 societies for a lead here as a function of different like PT thresholds. So we don't 31 00:02:50,580 --> 00:02:54,570 see a significant modification of the charge distribution in lead compared to 32 00:02:54,570 --> 00:02:59,970 pee pee. We see similar compatible results in four four 33 00:03:00,000 --> 00:03:01,590 On cases ppm a lead 34 00:03:03,179 --> 00:03:08,729 so we see consistent fractions extracted from this template fits in ppm a lead for 35 00:03:08,729 --> 00:03:14,249 different similarities. And these conclusions don't really depend on the 36 00:03:14,279 --> 00:03:20,309 charge parameters. So the type e ticket as we see here, and also I'm not showing a 37 00:03:20,309 --> 00:03:25,589 scanning the value of the Discover parameter, but also results are what a 38 00:03:25,589 --> 00:03:26,009 senior 39 00:03:28,110 --> 00:03:34,920 let me move on now to a second measurements, which is a jet budget scan 40 00:03:34,980 --> 00:03:37,380 in the jet nuclear registration factor. 41 00:03:40,650 --> 00:03:50,730 So this is a JPEG and adjust the font measurement to white jets to articles one 42 00:03:52,470 --> 00:03:58,440 and two, in order to measure such wide Jetson in the lead we we have to use 43 00:03:58,470 --> 00:04:00,000 advanced techniques 44 00:04:01,410 --> 00:04:06,510 The blood I'm showing on the top right is the nice patien of the very underlying 45 00:04:06,510 --> 00:04:08,070 events even selection 46 00:04:09,599 --> 00:04:15,179 for candidate for the jets and we're using a for the estimation of the underlying 47 00:04:15,179 --> 00:04:21,149 events we're accounting for for the film in relation to here the x axis is the 48 00:04:21,449 --> 00:04:25,499 candidate phi. And this is used to estimate the 49 00:04:26,820 --> 00:04:31,830 the amount of an event activity under the jet and to correct for it when we make the 50 00:04:31,830 --> 00:04:33,330 measurements. And then the 51 00:04:34,350 --> 00:04:39,840 on the left you can see migration metrics is using the unfolding to generate 52 00:04:39,840 --> 00:04:40,860 valuable quantities. 53 00:04:42,330 --> 00:04:49,560 And then the the top is for now jet so I was open to and the bottom is for y jets 54 00:04:49,770 --> 00:04:56,070 equals one. And the next is for pspp. On the right is BGR plus hydrogen. So this is 55 00:04:56,070 --> 00:04:59,970 Linux events. So after all of this 56 00:05:00,570 --> 00:05:03,420 We come to the results which option is eight six. 57 00:05:05,100 --> 00:05:06,810 So, again this is the first measurement 58 00:05:07,980 --> 00:05:15,270 to this dislodged value of our there will be competing effects for wide jets. Of 59 00:05:15,270 --> 00:05:21,120 course where there is separation but then also when we go to larger angles, we could 60 00:05:21,120 --> 00:05:25,860 expect a recovery of quenched energy. So, based on previous measurements that 61 00:05:25,860 --> 00:05:26,730 studied the 62 00:05:27,990 --> 00:05:33,600 shape and the correlation between trikes and jets, we know that when we go to wider 63 00:05:33,600 --> 00:05:34,170 angles, 64 00:05:35,280 --> 00:05:37,290 we we expect to incur some 65 00:05:38,850 --> 00:05:45,840 quenched energy. These are those here four, four. So different values of our 66 00:05:46,320 --> 00:05:52,020 each of the panels for the different value of our intended existence jpg. And our 67 00:05:52,020 --> 00:05:56,100 data are compared to many models. Not all of them are shown in this box. 68 00:05:57,210 --> 00:06:00,000 And we see that the different models 69 00:06:00,000 --> 00:06:06,180 have very different predictions. So this gives interesting new constraints on jet 70 00:06:06,270 --> 00:06:07,500 jet quenching models. 71 00:06:09,480 --> 00:06:14,580 I'm moving now to Busan check correlations. So, we can use photons or z 72 00:06:14,580 --> 00:06:16,950 bosons as unmodified references 73 00:06:18,600 --> 00:06:22,560 for instance, z bosons and dedicate products to that syntax with the with the 74 00:06:22,560 --> 00:06:28,080 GP. And so, so, this is what is shown here and then this can be used as a reference 75 00:06:28,290 --> 00:06:35,100 to study the recording charged particles. And then we there are several possible 76 00:06:35,100 --> 00:06:39,180 observables such as Angular correlations, just fragmentation. 77 00:06:40,320 --> 00:06:43,140 I'm showing here one example from 78 00:06:44,430 --> 00:06:49,260 a paper and photo that photo tags events and this is a ratio 79 00:06:50,370 --> 00:06:53,370 of the judge shapes. So, this is the correlation between 80 00:06:55,590 --> 00:06:56,610 the tracks and 81 00:06:58,170 --> 00:06:59,970 the jet and we see here are 82 00:07:00,000 --> 00:07:06,510 modification, when comparing center led events making the issue to BP, especially 83 00:07:06,510 --> 00:07:07,830 at large angles. 84 00:07:10,110 --> 00:07:15,360 What I wanted to show here is a new result for this conference, this is the one 85 00:07:15,360 --> 00:07:16,170 collisions. 86 00:07:18,300 --> 00:07:23,610 The first thing I want to mention about this is that this is a very small signal 87 00:07:23,640 --> 00:07:29,460 on the show regarding Plex. So, if we look at the the y axis here, so this is the 88 00:07:29,610 --> 00:07:31,050 number of tracks 89 00:07:32,220 --> 00:07:35,430 as a function of the angle with the with the Z. 90 00:07:37,080 --> 00:07:40,740 And you see that we are really talking about just a few tweaks that we need to 91 00:07:40,740 --> 00:07:44,730 remove the very large underline even to be sensitive to this. And then we are 92 00:07:44,730 --> 00:07:51,810 contained peeps to let let TP is in blue and lettuce is in white. 93 00:07:53,790 --> 00:07:57,990 So we see significant modifications in the azimuthal angle solutions. 94 00:08:00,269 --> 00:08:05,249 Especially for central events, which are shown on the right compared to BP 95 00:08:06,899 --> 00:08:11,459 and also measured our fragmentation functions and had on PT spec coverage on 96 00:08:11,459 --> 00:08:16,709 the change here. For more information and putting the difference at the top here, I 97 00:08:16,709 --> 00:08:19,889 think it's not valuable but it should be in your house. 98 00:08:22,110 --> 00:08:28,380 Again, Moving now to kind of heavy flavor jet results, starting with 99 00:08:29,400 --> 00:08:32,400 mesons in jets positions. 100 00:08:36,000 --> 00:08:41,850 So here what we're studying is the various profiles of Jamaicans and jets. And we're 101 00:08:41,850 --> 00:08:46,260 studying the as a function of the angle between the jet axis and 102 00:08:48,150 --> 00:08:55,560 against studying this in ppl collisions within this kinematic equation which is 103 00:08:55,560 --> 00:08:56,460 written on the blood 104 00:08:57,840 --> 00:08:59,970 So comparing PP and E 105 00:09:00,000 --> 00:09:02,040 blue light and when we see that 106 00:09:03,300 --> 00:09:06,960 they they are consistent with the uncertainties but there is a hint for 107 00:09:06,960 --> 00:09:09,840 wider distribution in the lead to BP 108 00:09:11,550 --> 00:09:14,340 at at low p t, so I'm showing only one of the two 109 00:09:15,599 --> 00:09:22,649 branches, which are we change up here. And so this is sensitive to the charm Quark 110 00:09:22,649 --> 00:09:25,349 division with the Texas 111 00:09:27,240 --> 00:09:35,910 salon heavy flavor this time, beauty. So we also studied beach shaved this thing. 112 00:09:36,060 --> 00:09:38,190 This is the DNA center shooting for 113 00:09:39,390 --> 00:09:43,620 in this store that is only PP at live TV. 114 00:09:44,730 --> 00:09:47,010 So here again, we have the Git shake, which is 115 00:09:48,750 --> 00:09:53,700 looking at the equation between the tracks and the jetpacks is a sufficient angular 116 00:09:53,700 --> 00:10:00,000 distance between the two and we see two things here. The 117 00:10:00,000 --> 00:10:05,580 First one. So what is shown here is the ratio of the gap between PJs and infinity 118 00:10:05,580 --> 00:10:08,700 jets, we see that the issue is not once we do have 119 00:10:10,410 --> 00:10:15,360 a difference, a different shape with respect to the Jets. And we see also that 120 00:10:15,810 --> 00:10:17,070 the PTM 121 00:10:19,109 --> 00:10:24,329 prediction is shown in blue. It's not on top of the data so it's not perfectly 122 00:10:24,329 --> 00:10:25,799 modeled by PCR. 123 00:10:27,000 --> 00:10:33,270 So so we have a flavor dependence of the pattern fragmentation in beauty 124 00:10:35,130 --> 00:10:38,910 and for the last few minutes I want to 125 00:10:41,130 --> 00:10:42,030 is on this 126 00:10:43,590 --> 00:10:45,360 also recent results that 127 00:10:47,580 --> 00:10:53,430 flashed this morning a few hours ago in the plenary session, which is the Watson 128 00:10:53,460 --> 00:10:59,910 helium collisions. First, I'll give a short introduction about quarks to the as 129 00:11:00,000 --> 00:11:04,680 hops they are produced early in the equation, but they also decay very, very 130 00:11:04,680 --> 00:11:07,830 fast educate before the GP is formed. 131 00:11:10,320 --> 00:11:16,080 They can be used as opposed to nuclear yes and they will be performing high x 132 00:11:16,080 --> 00:11:18,780 clearance and say that 133 00:11:21,030 --> 00:11:27,570 nugget out longer term plan for using this probe is to point to the formation time of 134 00:11:27,570 --> 00:11:35,940 the GGP since with much more data than we have now, we could study the the 135 00:11:37,260 --> 00:11:40,290 community note independence of the 136 00:11:42,870 --> 00:11:43,950 production 137 00:11:45,120 --> 00:11:48,960 cost as a function of the RPG and putting 138 00:11:50,220 --> 00:11:52,380 different times inside the GP. 139 00:11:53,610 --> 00:11:57,840 As what is shown on top left is an even display where we see 140 00:12:00,450 --> 00:12:08,010 The characteristics of this device This is a pair, today's Wednesday the electron and 141 00:12:08,010 --> 00:12:10,260 the tube detects detect jets 142 00:12:11,519 --> 00:12:17,489 which we can I find the Feynman diagram and so, we have to be to the ribosomes 143 00:12:17,489 --> 00:12:23,129 which lipnicki then two digits coming from the quantities. 144 00:12:25,320 --> 00:12:29,640 Okay, so we're focusing under that telephone channel, the branching ratio is 145 00:12:29,670 --> 00:12:34,170 rather small as you can see here in this pie chart, but the advantage is that we 146 00:12:34,170 --> 00:12:38,370 have a clean final state with the two the to leptons 147 00:12:40,050 --> 00:12:45,060 also they are unaffected by the cutiepie. So most of the sensitivity is coming from 148 00:12:45,060 --> 00:12:51,450 the immune final state, because the radiant background is following this. This 149 00:12:51,450 --> 00:12:58,020 final stage it would be coming from very young to data, but we also considering the 150 00:12:58,050 --> 00:12:59,640 dialect on Indian channels. 151 00:13:00,000 --> 00:13:04,890 Excluding the gms region, since this provides additional sensitivity, and it's 152 00:13:04,890 --> 00:13:08,100 also a way to control the modeling of the backgrounds. 153 00:13:09,570 --> 00:13:15,540 So as I mentioned in these events will expect to hype hype egb jets. But we 154 00:13:15,540 --> 00:13:20,310 repeated the analysis with and without using this, this information. So this is a 155 00:13:20,310 --> 00:13:25,800 way to to balance either hopelessness, if you don't use the bijection, then we are 156 00:13:25,800 --> 00:13:30,330 completely only relying on the under leptons, which are very wet measures. And 157 00:13:30,330 --> 00:13:35,970 then we can also include the beach so that we we have a better sensitivity. And one 158 00:13:35,970 --> 00:13:40,650 thing that I also want to stress here is that it's not so often that we do this in 159 00:13:40,650 --> 00:13:47,190 heavy data analysis, but we developed the analysis techniques using only one third 160 00:13:47,190 --> 00:13:53,250 of the full data set. So in such that we were not sensitive to the signal in such a 161 00:13:53,310 --> 00:13:56,580 small amount of data. And once everything was 162 00:13:57,870 --> 00:13:59,970 designed and finalized, then 163 00:14:00,179 --> 00:14:04,109 Only then we will look at the full dataset. I mean, do you have two more 164 00:14:04,109 --> 00:14:05,939 minutes? Okay, thank you. 165 00:14:08,400 --> 00:14:13,560 So these are the results on the left, what I'm showing is the dialect on general 166 00:14:13,560 --> 00:14:17,700 without the digits. So what I haven't mentioned so far is that this is a 167 00:14:17,700 --> 00:14:23,070 multivariate analysis we're using within the decision trees. And we see here the 168 00:14:23,070 --> 00:14:29,220 signal in whites at high value values of stability. And then on the right, this is 169 00:14:29,220 --> 00:14:35,040 when we add the counting of digits, we make categories to be just one digit to be 170 00:14:35,040 --> 00:14:44,550 just as expected, the signal is mostly in the 1d and 2d categories. And in this way, 171 00:14:44,550 --> 00:14:46,890 we have a better sensitivity. 172 00:14:48,270 --> 00:14:54,060 All in all, we have four sigma significance. So this is not we are below 173 00:14:54,060 --> 00:14:56,910 five sigma. But this is all based on evidence, very strong evidence. 174 00:14:58,170 --> 00:14:59,970 And this is the mutual connection. 175 00:15:00,000 --> 00:15:05,760 Compared to what we get in BP and also compared to predictions. 176 00:15:08,189 --> 00:15:13,889 See that's our measurement is slightly below the prediction which is consistent 177 00:15:13,889 --> 00:15:14,159 with it. 178 00:15:15,690 --> 00:15:20,940 So I'm coming to my summary, the lab large data samples from ADC when to give access 179 00:15:20,940 --> 00:15:26,700 to power probes and higher precision. So this is a list of what I've presented so 180 00:15:26,940 --> 00:15:27,210 far. 181 00:15:29,190 --> 00:15:34,860 We have access to this new and better ways to to study the properties and putting 182 00:15:34,860 --> 00:15:43,800 links to more results, which I haven't covered today. And this is an into to zoom 183 00:15:43,830 --> 00:15:47,760 if some people want to discuss after the session. Thank you. 184 00:15:49,320 --> 00:15:53,760 Very many thanks for showing us all of these beautiful results in media. So we 185 00:15:53,760 --> 00:15:59,400 have now time for questions both to this presentation and to all of the 186 00:15:59,400 --> 00:16:00,000 presentations. 187 00:16:00,000 --> 00:16:05,880 that we've seen today. So we can discuss in general hardware probes and heavy 188 00:16:05,880 --> 00:16:10,260 items, or we can have specific questions related to these talks. 189 00:16:12,000 --> 00:16:17,430 So the way this will work is if you press the raised hand button in zoom, then I can 190 00:16:17,430 --> 00:16:25,260 call on the various people and unmute everybody. So please go ahead and do that. 191 00:16:25,290 --> 00:16:29,490 If it doesn't work, just write a message in the chat and then we will also see your 192 00:16:29,490 --> 00:16:30,240 question there. 193 00:16:38,550 --> 00:16:42,180 Yes, I see brother has the first question. Please go ahead. Wow, hello. 194 00:16:43,350 --> 00:16:48,990 Yeah, congratulations on this nice measurement of Tiki Bar production by CMS. 195 00:16:49,320 --> 00:16:54,150 Actually, I wanted to ask two questions related to that topic. The first one is 196 00:16:54,150 --> 00:16:58,440 related to retardant techniques. Could you tell us a little bit about protecting 197 00:16:58,440 --> 00:16:59,550 performance in 198 00:17:00,269 --> 00:17:04,079 The lead lead system and another question is about 199 00:17:05,670 --> 00:17:12,330 nuclear modifications to PDF. How you want to explore that topic forever in the 200 00:17:12,330 --> 00:17:12,900 future? 201 00:17:14,130 --> 00:17:19,860 Yes. Okay. So I'll start with B tagging. So, we used techniques which are similar 202 00:17:19,860 --> 00:17:24,270 to what is used in collisions with a limited via discriminant for for V 203 00:17:24,270 --> 00:17:30,900 tagging, but it was trained specifically for for optimized for heavier 204 00:17:31,080 --> 00:17:35,280 environments. And then the performance of it was 205 00:17:37,410 --> 00:17:38,070 also 206 00:17:39,810 --> 00:17:41,430 also studied and 207 00:17:45,180 --> 00:17:52,200 machine on simulation but we also so in order to, to extract the connection 208 00:17:52,200 --> 00:17:55,800 measurements using critical information, we have to assume 209 00:17:57,390 --> 00:18:00,000 jet punching and we 210 00:18:00,329 --> 00:18:04,409 We included chickeny jet quenching effects in the analysis. 211 00:18:05,670 --> 00:18:13,170 But we with weather, conservative uncertainties on the amount of quenching 212 00:18:13,770 --> 00:18:19,110 and we designed the analysis such that, I mean, we're really only counting digits, 213 00:18:19,140 --> 00:18:26,580 we are not too sensitive to the details of the tagging efficiency of fake rates. We 214 00:18:26,580 --> 00:18:30,630 don't have so much fake right, there's actually an audit question. So 215 00:18:32,460 --> 00:18:38,550 that this is also why we have the two versions of the energies and we're 216 00:18:40,080 --> 00:18:44,430 confident in our results with using the tagging but then 217 00:18:45,600 --> 00:18:50,490 the other one is also there to show that they know that things are consistent even 218 00:18:50,760 --> 00:18:56,970 when you don't use anything. And the second question was about PDFs. So as you 219 00:18:56,970 --> 00:19:00,000 see, as of today, we have barely 220 00:19:00,000 --> 00:19:06,960 And observation, so when it's still not say, very sensitive to the fact Yes. 221 00:19:08,099 --> 00:19:12,419 But it's still interesting that we have this new process which is focusing on the 222 00:19:12,419 --> 00:19:17,729 ones, which is also possible to study important acquisitions as we had the 223 00:19:17,729 --> 00:19:23,039 observation couple of years ago in this system. So we think together in small 224 00:19:25,830 --> 00:19:32,340 midterm goal that well, now we have this data, and maybe they can provide a bit 225 00:19:32,850 --> 00:19:35,490 more sensitivity in the high x region. 226 00:19:41,850 --> 00:19:42,270 Thank you. 227 00:19:44,070 --> 00:19:45,420 Yeah. Thanks, everyone, and thanks. 228 00:19:46,680 --> 00:19:48,270 Are there other questions? 229 00:19:54,570 --> 00:19:57,060 Okay, I see a question from heavier 230 00:19:58,530 --> 00:19:59,370 Yeah. Hi. This is 231 00:20:00,510 --> 00:20:06,630 So, just to answer to the earlier question by by them on that presentation. So in 232 00:20:06,930 --> 00:20:13,530 this we need to have the Sigma two s and Q one s as a function of multiplicity MPP. 233 00:20:13,530 --> 00:20:14,310 Coalition's. 234 00:20:15,750 --> 00:20:20,460 There are some preliminary results, and there is a paper in preparation with more 235 00:20:20,460 --> 00:20:24,150 data that will come in next few months. 236 00:20:26,520 --> 00:20:26,880 Thank you. 237 00:20:29,460 --> 00:20:33,030 Great, thanks. It'll be very interesting to see the results from Alice, which we 238 00:20:33,030 --> 00:20:36,630 can also look back at the previous results from CMS and compare as well. 239 00:20:38,070 --> 00:20:44,400 There is also a poster that will be on this topic, but I'm not sure about the 240 00:20:44,400 --> 00:20:45,090 content. 241 00:20:50,520 --> 00:20:54,840 I'll get good. Yes, that's a good point. So just to everybody to advertise the 242 00:20:54,840 --> 00:20:59,040 poster session where we will be seeing more results from all of our experimental 243 00:20:59,040 --> 00:20:59,970 colleagues there. Yes. 244 00:21:04,500 --> 00:21:06,570 So are there further questions? 245 00:21:09,960 --> 00:21:13,470 I know unfortunately Mario's have to leave which is too bad because I had a question 246 00:21:13,470 --> 00:21:18,090 about the Atlas results, but we can of course ask via email also later. 247 00:21:19,980 --> 00:21:22,740 Sir, anything anyone wanted to discuss now? 248 00:21:47,910 --> 00:21:53,760 Okay, I see no further hands being raised and since it is near the end of our 249 00:21:53,760 --> 00:21:54,360 session 250 00:21:56,370 --> 00:22:00,000 I will remind you that most of our panelists have created 251 00:22:00,000 --> 00:22:06,300 Added sort of a Zoom Room where you're welcome to go join and chat with them. At 252 00:22:06,300 --> 00:22:12,240 the end of this session. The point is here that that we are missing our coffee break 253 00:22:12,240 --> 00:22:16,740 chats because we're doing this conference online. So we have encouraged all speakers 254 00:22:16,740 --> 00:22:22,050 to create a Zoom Room for after their session where people can go and discuss 255 00:22:22,050 --> 00:22:28,140 more and have more detailed conversations. So all of those links were in the slides, 256 00:22:28,170 --> 00:22:33,510 but I will actually also post them in the chat window now so that you can click on 257 00:22:33,510 --> 00:22:38,790 them and the password will be the same as the password that you had to get into this 258 00:22:38,790 --> 00:22:44,970 room. So let me post to those links. And of course, if anybody has any further 259 00:22:44,970 --> 00:22:46,980 questions, then we're happy to take them now.
