1
00:00:02,070 --> 00:00:09,840
Thanks sorry that I cannot make the full
screen of my slides. So, I have only

2
00:00:09,840 --> 00:00:16,140
working on this way and so my talk will be
on associated production in PvP and how

3
00:00:16,140 --> 00:00:24,270
they have AI installations. So first some
discriminate because because associated

4
00:00:24,300 --> 00:00:28,590
particle production is very broad topics
so it's it's going to be interesting

5
00:00:28,770 --> 00:00:33,990
interesting for thousands of reasons
right. So, me Of course, we should ask our

6
00:00:33,990 --> 00:00:38,850
questions is we why we are interested in
these associate production process of

7
00:00:38,850 --> 00:00:43,290
course, we we are interested in that
aspect to that is single inclusive

8
00:00:43,290 --> 00:00:44,820
particle production usually has

9
00:00:45,600 --> 00:00:47,970
much lyrics cannot tell us or tell

10
00:00:48,000 --> 00:00:50,700
us in a very limited way. But even that,

11
00:00:50,820 --> 00:00:55,680
I think it's impossible to cover
everything even not I mean, cover some of

12
00:00:55,680 --> 00:01:02,400
them overview of all interesting aspects,
right. So I Here is just a bigger one

13
00:01:02,400 --> 00:01:07,440
point I would like to talk here. So the
point I will talk is, is I mean, I'm

14
00:01:07,440 --> 00:01:11,910
working a bit on especially on
phenomenology side, about the double

15
00:01:11,910 --> 00:01:16,740
bottom scattering at hc Actually, we
already see a few of the measurement new

16
00:01:16,740 --> 00:01:24,240
measurements that was reported already in
this conference. So double paddle

17
00:01:24,240 --> 00:01:30,330
scattering. Usually, I mean we use in the
hc fullness right? So the cross section,

18
00:01:30,660 --> 00:01:36,900
and you I mean, you you can, all the cross
sections, we calculate the HST based on

19
00:01:36,900 --> 00:01:41,280
some factorization, zero factorization
conjecture. So that's the convolution of

20
00:01:41,280 --> 00:01:45,060
the partial distribute function and, and
the pythonic cross section that can be

21
00:01:45,060 --> 00:01:50,640
perturbative calculated. Usually that we
don't care about double bottom scattering

22
00:01:50,640 --> 00:01:55,410
because if you looking at the Julian's
just inclusive productions there, of

23
00:01:55,410 --> 00:02:01,410
course you allow a lot of the softer
interactions at the at the exit. An MPI I

24
00:02:01,410 --> 00:02:06,390
mean, but but if you do not ask to detect
these eggs, usually, I mean unitarity

25
00:02:06,420 --> 00:02:11,670
guarantee that you, you don't care these
right just just looking at one pattern

26
00:02:11,670 --> 00:02:15,480
scattering with another part of skirts in
front and that'd be to produce the

27
00:02:15,510 --> 00:02:22,140
producer laptop pair for example. But if
as long as you ask questions that how

28
00:02:22,230 --> 00:02:28,650
things happens when I detected both my
laptop and AIX, then you are going to

29
00:02:28,650 --> 00:02:34,620
something of a mechanical production that
you needed to know what these interaction

30
00:02:34,620 --> 00:02:39,030
happens here right? The example is, for
example, Higgs production z and Higgs

31
00:02:39,030 --> 00:02:43,920
associate production right. So, if the two
are both of the interactions, could it be

32
00:02:43,920 --> 00:02:49,350
hard that is allow you to do some
perturbative calculations then you you are

33
00:02:49,350 --> 00:02:54,630
working in the in the usual I mean master
formalism of the factorization serum. It's

34
00:02:54,630 --> 00:02:59,910
called the double bottom scattering and
these actually this kind of I mean, this

35
00:02:59,910 --> 00:03:04,440
is Kind of mechanics has contributed a lot
both for some signals if you're interested

36
00:03:04,440 --> 00:03:08,130
that you get interested in the development
of scattering studies or to the

37
00:03:08,130 --> 00:03:15,750
backgrounds right he example is effects
production, but I mean of course, this

38
00:03:15,780 --> 00:03:20,910
sometimes you need to care or of course,
the DPS productions well, but for these I

39
00:03:20,910 --> 00:03:26,310
mean probably not relevant, I will tell
you that because usually DPS is high test

40
00:03:26,490 --> 00:03:31,800
contribution, so usually power suppressed
to come down to the single scattering. But

41
00:03:31,860 --> 00:03:36,780
I mean DPS can be enhanced it right. So if
you see that you have the two part tonic

42
00:03:36,810 --> 00:03:43,650
incoming platonic PDFs if you're you have
PDF, you have go to high high energy. So

43
00:03:43,650 --> 00:03:49,350
you have high high platonic densities like
bronze to the small eggs, then of course,

44
00:03:49,350 --> 00:03:55,410
you enhance your sketching subsections. So
normally, that single paddles scattering

45
00:03:55,410 --> 00:03:59,370
you just said the at hc, for example, it's
just at the bottom density squared, but

46
00:03:59,790 --> 00:04:07,710
for DPS advanced scattering paddle density
photos and then how to blow up with the

47
00:04:07,710 --> 00:04:12,630
double bottom scattering SDHC. And while
we I mean since we know that the power

48
00:04:12,630 --> 00:04:18,090
counting about the other part of
scattering first of course, if we do not

49
00:04:18,090 --> 00:04:23,730
go to extremely large scale, we just go to
some low scales a bit low but still in the

50
00:04:23,730 --> 00:04:29,010
perturbative region for example, some
hydro on the heavy flower production or

51
00:04:29,010 --> 00:04:33,300
the accordion productions right in
principle these surprises not so much. So,

52
00:04:33,300 --> 00:04:38,190
you have the you have the chance you have
heard to extract the significant GPS

53
00:04:38,190 --> 00:04:45,480
components and also you of course, you can
see me Similarly, you can see some large

54
00:04:45,480 --> 00:04:48,840
yields production for example, not
particularly hard yards but you're looking

55
00:04:48,840 --> 00:04:54,330
at the more inclusively like the jet mouse
jet productions they have a lot of I mean

56
00:04:54,330 --> 00:05:00,000
large yields cross sections. So the
normally you have to see some DPS company

57
00:05:01,650 --> 00:05:06,960
All you can precise measure this process
then you may see some very small

58
00:05:07,320 --> 00:05:12,720
deviations compared to your SPS
simulations. And also I mean it's it you

59
00:05:12,720 --> 00:05:18,570
need to be very precise measurements also
very precise calculations in this case to

60
00:05:18,600 --> 00:05:24,270
strap the GPS and then also if you're good
high high energy as I say the main if he

61
00:05:24,360 --> 00:05:29,550
becomes a VPS is is part of the density of
the full dependency with respect to the

62
00:05:29,550 --> 00:05:35,430
SPS squared. So if you get high energies
of course the enhancement is is more

63
00:05:35,460 --> 00:05:42,360
repetitive in the DPF thing, then SPS. So,
you go to a tv 14 tv to even hundred TV Of

64
00:05:42,360 --> 00:05:48,090
course 200 TV you will you'll see even
more processes

65
00:05:48,120 --> 00:05:48,780
in principle

66
00:05:49,560 --> 00:05:56,160
and also you can go to the ion sir because
if you go to the proton nuclear or nuclear

67
00:05:56,160 --> 00:06:01,740
nuclear coalition, so each each each
collisions you Have you have the

68
00:06:01,800 --> 00:06:06,150
enhancements from that because you have a
lot of nuclear enters into your

69
00:06:06,150 --> 00:06:13,410
collisions. So you will see that the
enhancements of DPS is more quickly then

70
00:06:13,650 --> 00:06:14,340
then the

71
00:06:14,970 --> 00:06:15,750
SPS

72
00:06:17,490 --> 00:06:19,830
I will go to these ponds later.

73
00:06:21,180 --> 00:06:27,720
So, the good thing is like SPS I mean like
single particle scattering we right now we

74
00:06:27,720 --> 00:06:32,040
have settled theory foundation that is
proved completely proven fact law So, you

75
00:06:32,040 --> 00:06:35,670
can see a room for the double bottom
sketch of course, I mean for the color

76
00:06:35,670 --> 00:06:41,550
singlets final state Doubletree. Yeah but
also even for SPS we only approved the

77
00:06:41,580 --> 00:06:46,800
kind of single is final states. So, in
principle, I mean, this is the two papers,

78
00:06:46,830 --> 00:06:52,950
I prefer the two, the first paper trying
to resolve the coming to see that all the

79
00:06:53,520 --> 00:06:58,080
billable grounds can be factorized, and a
second amount to finalize all the softer

80
00:06:58,110 --> 00:07:03,270
sub graphs, you'll see that the picture
So, right now, in principle we can say

81
00:07:03,270 --> 00:07:09,120
that okay we can write to the cross
section of the two particle I mean to

82
00:07:09,180 --> 00:07:14,730
interaction final state production can be
writing in fact lies the way that is each

83
00:07:15,990 --> 00:07:20,490
each one each and this is one atomic
scattering and then the second pattern is

84
00:07:20,490 --> 00:07:26,190
cancelled and convoluted is some general
lies that double Patil foundation sorry

85
00:07:26,250 --> 00:07:32,370
Patil pattern distribute functions, okay.
So, here this is you can also view that,

86
00:07:32,850 --> 00:07:36,900
this kind of way, if you imagine VPS What
do you can learn Of course, you can learn

87
00:07:36,900 --> 00:07:41,610
that So, you have a new way to access the
information of the non fungible structure

88
00:07:41,610 --> 00:07:46,560
of nucleotides that is not can provide in
the in one body in a single part of

89
00:07:46,560 --> 00:07:51,870
scattering that's usually relates to one
body atomic structures. So, he has to say

90
00:07:51,870 --> 00:07:56,640
that you you, you have the generalized the
double part on distributions and these two

91
00:07:56,640 --> 00:08:03,780
is simply the platonic scattering tu tu tu
tu egg scattering if you want okay? Of

92
00:08:03,780 --> 00:08:09,780
course it still I mean we starting from
these these forms we can I mean there's a

93
00:08:09,810 --> 00:08:15,510
large unknown from these two Nativity
functions that matter also matter the bank

94
00:08:15,600 --> 00:08:22,170
dimensional the Y the spirit things we
needed to do some simplifications, okay?

95
00:08:22,470 --> 00:08:27,960
So most of phenomenology actually rely on
all these strong assumptions. That is

96
00:08:27,960 --> 00:08:35,490
you're assuming that your your general
patterns and functions can be factorized

97
00:08:35,520 --> 00:08:39,870
out into the longitude boards and the
transfers boards and also the longitude

98
00:08:39,870 --> 00:08:44,730
part actually, you can you can factorize
out and that can be factored out. Okay. So

99
00:08:44,730 --> 00:08:50,250
this is the usual a PDF, single one body
single PDF and these double double PDF,

100
00:08:50,280 --> 00:08:55,800
okay. And also, I mean, if you assuming
there's just to get rid of the idea

101
00:08:55,800 --> 00:09:02,310
dependency, you have the one single just
the ones perturbative sorry non

102
00:09:02,310 --> 00:09:09,000
perturbative number okay to to predict to
predict all the DPS sections Valley

103
00:09:09,000 --> 00:09:12,990
predictive but of course you can cast to
the in adults that way that these

104
00:09:13,020 --> 00:09:19,140
assumptions are valid general but even me
even you can get rid of some of the

105
00:09:19,170 --> 00:09:23,940
federalization assignment simplification
so you just have starting from these that

106
00:09:25,050 --> 00:09:30,720
this double PDF actually there's only one
okay in the market because they are very

107
00:09:30,720 --> 00:09:37,410
very complicated to solve these is already
included a multi dimensional structure

108
00:09:37,410 --> 00:09:40,890
also even for the evolution itself you
gotta be collaborative who have

109
00:09:40,890 --> 00:09:44,790
evolutions. it's valid it's very
complicated. So there's I left a few

110
00:09:44,790 --> 00:09:49,320
papers you if you're interested in the
last few studies on these on these

111
00:09:49,320 --> 00:09:57,180
collections. So in general, the philosophy
we have to how to how to be preceded for

112
00:09:57,210 --> 00:10:03,840
Ah, phenomenology is, let's ask justice.
If we simply pop the formula and we

113
00:10:03,840 --> 00:10:08,700
compare with our predictions with with the
experimental data, and if we find some

114
00:10:08,700 --> 00:10:12,060
deviations and we trust all our
measurements or trust all of the

115
00:10:12,060 --> 00:10:18,120
calculations in this film here we can see
that these deviations can be calling for

116
00:10:18,120 --> 00:10:24,570
the sum more leg loss treatment, okay. So,
there are a few a few possible deviations

117
00:10:24,570 --> 00:10:30,690
to compare to the pocket formula. I just
pick up a few examples. First is if you go

118
00:10:30,690 --> 00:10:37,800
to the devil, I mean you do not use these
federalized PDF double PDF you just just

119
00:10:37,800 --> 00:10:42,930
working collecting these double PDF and
you do the double Ecolab evolutions. Of

120
00:10:42,930 --> 00:10:44,580
course you don't know what's the initial

121
00:10:46,110 --> 00:10:51,390
assuming that the initiative scalable PDF
is same as as in a scale of a single PDF

122
00:10:51,390 --> 00:10:56,940
squared. Then you perform the evolution.
You see that there's a difference is

123
00:10:56,940 --> 00:11:02,610
blonde blonde over two grams at the end
case with higher electric scale, you will

124
00:11:02,610 --> 00:11:12,210
see that for the the most I mean probation
seems lafley Okay, I mean 10% 20% for most

125
00:11:12,240 --> 00:11:17,220
of x regions, except at the extremely high
x reaches, okay you have you have some

126
00:11:17,220 --> 00:11:23,190
problem. I mean these apparently not
working work well and mo and the second

127
00:11:23,190 --> 00:11:29,850
one is, I mean, when you work in the
perturbative qc approach, you will see

128
00:11:29,850 --> 00:11:35,370
that actually not only have the two v two
scattering, okay, you in fact have the

129
00:11:35,370 --> 00:11:40,320
perturbative non perturbative wrong comes
out from the front. Hi, john Dang, the

130
00:11:40,320 --> 00:11:44,700
drunk and the debaters sprinting into the
two patterns then have the scatterings

131
00:11:44,700 --> 00:11:51,510
code the two two v 2222 v 101 v two, okay.
In principle you need to include because

132
00:11:51,510 --> 00:11:55,590
this is not including a single pattern
scattering calculations well, right. So,

133
00:11:56,370 --> 00:12:00,690
you needed to include all of these
contribution but you can argue that some

134
00:12:00,690 --> 00:12:05,700
point, this kind of contribution, could it
be? Since it's perturbative regions could

135
00:12:05,700 --> 00:12:10,230
have been an activity or the contributions
property suffers some points. But

136
00:12:10,230 --> 00:12:15,780
actually, the luminosity itself is not if
you just calculate the luminosity of the

137
00:12:15,810 --> 00:12:22,050
wrong with with two grounds. And also the
to mean for grants. I mean, you're for

138
00:12:22,050 --> 00:12:27,510
grants and one grant and two grants. So
three grants, if you see the one, the two

139
00:12:27,540 --> 00:12:33,990
or two the one compares to the two for the
two chip side and for the W and the cape

140
00:12:33,990 --> 00:12:37,860
side mass, which means you will see that's
the actually compatible.

141
00:12:39,570 --> 00:12:40,140
And

142
00:12:42,570 --> 00:12:47,910
then I mean, the third one is that is that
you can you can introduce a bit to the

143
00:12:47,910 --> 00:12:52,470
pattern pattern collections, you do not
assume zero correction, aka full name, oh,

144
00:12:52,800 --> 00:12:58,440
and then you ask yourself what happens in
that case? So then you will see some

145
00:12:58,470 --> 00:13:03,030
actually your stick by facts. Would it be
not a number in mo it would it be depends

146
00:13:03,030 --> 00:13:09,390
on some some convex like because the x one
x two and even some scares okay. So, this

147
00:13:09,390 --> 00:13:16,500
is this is a few papers and studies
include these for the study this same sign

148
00:13:16,530 --> 00:13:24,900
up a W you see that these these long one
is human zero collisions but if you if you

149
00:13:24,900 --> 00:13:30,240
have to put the collisions in you will see
some the Sigma factor extracted from the

150
00:13:30,240 --> 00:13:37,170
different climatic regions it's a new one
new to eat I want you to is is just the

151
00:13:37,170 --> 00:13:38,580
liquidity of the of the

152
00:13:39,720 --> 00:13:40,740
web. Okay.

153
00:13:41,490 --> 00:13:44,970
You have about two minutes left so I think
it may be necessary to speed up

154
00:13:45,299 --> 00:13:50,669
Yeah, okay, thanks IV IV quickly I could
go through. So you will see that there are

155
00:13:50,669 --> 00:13:55,019
some bitter, bitter dependent but it's
very challenging because the DPS sip

156
00:13:55,079 --> 00:14:01,769
itself in the WWE already very small, they
projected to see that you mean that if you

157
00:14:01,769 --> 00:14:06,959
find some one sigma deviation from the
first being into the last day licklider

158
00:14:06,959 --> 00:14:12,239
1000. Emerson's about to observe these
colors so the dependence is quite weak

159
00:14:13,349 --> 00:14:14,939
so actually there's a lot Hobbes

160
00:14:14,970 --> 00:14:19,470
says it quickly goes through so there's a
if you see that the plot you will see them

161
00:14:19,740 --> 00:14:27,960
many jets measurements of final state and
hc the photons as the W z bosons or

162
00:14:27,960 --> 00:14:36,990
observed the DPS have a flavor own use and
W Yeah, okay. Of course, here I plot the

163
00:14:37,080 --> 00:14:41,040
Sigma factor from different entities you
see that about the uncertainty still large

164
00:14:41,040 --> 00:14:48,690
enough, but you will you may see some non
universal super effective patterns okay.

165
00:14:48,870 --> 00:14:52,170
So you can ask question with this rather
dependent energy dependent kinematic

166
00:14:52,170 --> 00:14:58,620
dependence. So this is also see the talk
on the Tuesday there's supposedly sensor

167
00:14:58,620 --> 00:15:04,830
same w this one The T by CMS. So, of
course there's a caveat to that. There's a

168
00:15:04,830 --> 00:15:09,840
traveling thing to differentiate SPS DPS
is easily expand ours, we can discuss all

169
00:15:09,840 --> 00:15:11,490
these how to extract the visa.

170
00:15:12,599 --> 00:15:13,259
This

171
00:15:13,289 --> 00:15:17,909
one example concrete example gave is the
oops wrong magnify this arrow at the

172
00:15:17,909 --> 00:15:23,279
beginning they assume there's no DPS SPS
and then you extract all the DPS the value

173
00:15:23,309 --> 00:15:28,739
if you Sorry, if you go to the include a
bit of SPS you will see that value I mean,

174
00:15:28,799 --> 00:15:33,749
especially automatic changes this cabinet
but if you go to heavy ion, as I said,

175
00:15:33,749 --> 00:15:40,439
there's there's DPS enhanced today is in
particular for pa you see that is a factor

176
00:15:40,439 --> 00:15:46,289
of three A times of the day but to be
known as Ts, it's the scanning as a as no

177
00:15:46,289 --> 00:15:52,229
nuclear modification and it is even
enhanced mode. Of course, we know we

178
00:15:52,229 --> 00:15:56,189
cannot neglect to these nuclear
modifications, these examples for heavy

179
00:15:56,219 --> 00:15:59,669
flavor and a core corneum. You'll see that
the nuclear modification trade is very

180
00:15:59,669 --> 00:16:08,789
large. Probably 0.47 I mean RPA so we
accommodated on my paper, I tried to think

181
00:16:08,789 --> 00:16:12,809
about these questions and to accommodate
all the nuclear PT effect and the

182
00:16:12,809 --> 00:16:16,229
geometry, the previous release
pharmacology, I'm shooting back.

183
00:16:17,549 --> 00:16:18,149
So,

184
00:16:18,570 --> 00:16:24,900
I quickly goes through that you see that
the G delta G journalize double bottom

185
00:16:25,140 --> 00:16:31,620
structure functions right non dependence
on these impact parameters. And, if I mean

186
00:16:31,680 --> 00:16:35,010
these Likewise, we know actually the
nuclear modification at different

187
00:16:35,010 --> 00:16:38,850
positions, because it's one of the nuclear
means will be depends on the impact

188
00:16:38,850 --> 00:16:45,270
validators Actually, this has been this
kind of thing is is clashing to always be

189
00:16:45,270 --> 00:16:49,680
there as also you can also see from
previous token, you need assuming

190
00:16:49,680 --> 00:16:53,070
something of the impact paramita
dependence in the nuclear modifications.

191
00:16:53,430 --> 00:16:57,570
So, in the central clarity dependent
observables out there, but worldwide

192
00:16:57,630 --> 00:17:04,200
assumptions, these kind of functions can
linearly dependent on the on the on the

193
00:17:04,200 --> 00:17:10,470
sickness function. So, this gives us the
idea that actually DPS in hockey I have a

194
00:17:10,470 --> 00:17:15,060
equations can have the potential to
constrain these dependents okay. So, this

195
00:17:15,060 --> 00:17:20,160
is a concrete example I in my lesson
papers see that if you looking at to the

196
00:17:20,520 --> 00:17:25,650
proton and and lead Christians for the
website and the nasm production, you'll

197
00:17:25,710 --> 00:17:30,720
see that my DPS the nuclear modification
factor with depends on at i mean i

198
00:17:30,720 --> 00:17:36,330
assuming the my g function is just the
synchronous function time. So, that times

199
00:17:36,360 --> 00:17:41,640
a as opposed to a then you will see that
it depends on the on the single part

200
00:17:41,700 --> 00:17:47,580
single nuclear manufactured modification
factors and also geometry enhancement also

201
00:17:47,580 --> 00:17:49,590
the other terms comes.

202
00:17:50,130 --> 00:17:52,560
So, either actually these pieces you can

203
00:17:52,560 --> 00:17:56,430
calculate or fixed by other measurements
under the same conditions for example,

204
00:17:57,000 --> 00:18:01,140
right. So, in particular use I mean you
see that why there Such a tripping hazard

205
00:18:01,140 --> 00:18:07,050
and this kind of thing, in fact gives you
a very large enhancement. I mean if you're

206
00:18:07,050 --> 00:18:13,440
sick when in fact it's not small enough
small enough So here is an example that I

207
00:18:13,470 --> 00:18:19,170
studied. In my paper you see that for the
chips ID zero production as the period.

208
00:18:19,920 --> 00:18:26,370
The difference we have some description
power to differentiate the DPS components

209
00:18:26,370 --> 00:18:32,580
and SPS components and also DPS strongly
dependent on the assumption of a g

210
00:18:32,580 --> 00:18:39,810
function. Okay. This is RTA. So I quickly
I think, I quickly afresh these warming

211
00:18:39,810 --> 00:18:44,580
these are actually our first DPS
measurements in heavy IoT become soon by

212
00:18:44,640 --> 00:18:46,920
HCP has been seen on Wednesdays

213
00:18:47,040 --> 00:18:47,610
talk.

214
00:18:48,750 --> 00:18:55,440
So I go to my conclusion, associate
production is at hc actually opens a new

215
00:18:55,440 --> 00:18:59,460
area for studying GPS and if you have
witnessed a lot of theoretical and

216
00:18:59,460 --> 00:19:03,660
phenomenon logical and experiments
progress, but some theoretical issues

217
00:19:03,660 --> 00:19:08,640
still persist to better predict the future
is implied. And the main interesting

218
00:19:09,000 --> 00:19:14,700
measurements are coming. It's also
exciting time that the first GPA studying

219
00:19:14,700 --> 00:19:19,980
heavy is coming. And I believe that we can
definitely learn more from these these

220
00:19:19,980 --> 00:19:24,780
measurements this data, for example, I
give example the we can learn actually the

221
00:19:24,780 --> 00:19:29,010
impact on the dependent nuclear power
distributed functions. And you can also

222
00:19:29,010 --> 00:19:35,250
sync that other nuclear modification
factors, how these can be included in the

223
00:19:35,280 --> 00:19:36,990
in these DPS focus.

224
00:19:37,860 --> 00:19:42,870
Okay, thank you. Thank you very much
rushing for this very comprehensive and

225
00:19:42,870 --> 00:19:47,310
detailed talk. It's very interesting. Now
in order to keep up with the schedule, I

226
00:19:47,310 --> 00:19:53,370
think we probably did not have time for a
question right now. But we are of course

227
00:19:53,370 --> 00:19:58,200
able to come back and discuss and ask
questions about this set of slides and

228
00:19:58,200 --> 00:20:00,480
this nice presentation during our
discussion. session.

229
00:20:01,650 --> 00:20:04,020
So let's think crushing again and we move
