1
00:00:02,040 --> 00:00:02,730
Hear Me?

2
00:00:03,000 --> 00:00:04,380
Yes please start when you're ready.

3
00:00:05,130 --> 00:00:09,870
Okay, so this is morning from central
China and Memorial University on behalf on

4
00:00:10,440 --> 00:00:15,150
CB collaboration. Next I will give an
introduction about the measurements and

5
00:00:15,150 --> 00:00:19,290
the prospects on electronic physics from
RCB experiment.

6
00:00:20,610 --> 00:00:24,120
I'm mainly and I can't see your slides
anymore I don't know whether the other

7
00:00:24,120 --> 00:00:30,060
convenience also have this problem. Yes,
maybe your day somehow disappeared when

8
00:00:30,060 --> 00:00:31,080
you went to full screen.

9
00:00:31,290 --> 00:00:33,330
Now I can see them okay.

10
00:00:38,310 --> 00:00:44,700
So at first I will do a introduction but
our detectors. Our detector is single arm

11
00:00:44,700 --> 00:00:48,990
forward spectrometer power ratings are
very unique acceptance in the forward

12
00:00:48,990 --> 00:00:54,990
regions, and the design for the 30s of the
protocols continues to be undersea cracks,

13
00:00:55,380 --> 00:00:59,970
and the RCP Taurus creates instability in
the electroweak physics and the tracks

14
00:01:01,260 --> 00:01:06,840
Because our CV is the only filter as an RC
with the precision tracking coverage in

15
00:01:06,840 --> 00:01:12,750
the forward region and it has excellent
momentum resolution, high new either the

16
00:01:12,750 --> 00:01:18,810
efficiency and the how or good performance
of the electronic reconstruction. And our

17
00:01:18,810 --> 00:01:24,660
CB detector has a silent or texted
reconstruction which can help tag B and C

18
00:01:24,660 --> 00:01:33,150
guides your to the unique four regions
that are CB car size, new kinematic range

19
00:01:33,150 --> 00:01:40,110
to offer complimentary speak range with
respect to authorize and CMS for

20
00:01:40,110 --> 00:01:45,960
electronic measurements. And they could
also allow sensitivity to PDF items high

21
00:01:45,960 --> 00:01:54,870
values and low x values which is explored
by other experiments are to be performed

22
00:01:54,870 --> 00:02:00,180
some measurements of the atomic physics in
the recent three years into cells In the

23
00:02:00,180 --> 00:02:05,490
16th RCB data the total and differential
cross section measurements of the W and z

24
00:02:05,490 --> 00:02:12,870
production in associations with jazz use
in 2010. data at at a measurement of

25
00:02:12,900 --> 00:02:18,120
vector both on production in associations
with the drugs in the forward regions is

26
00:02:18,120 --> 00:02:23,790
important to test the PDF and provide
constraints on the test to the same model

27
00:02:23,790 --> 00:02:29,820
and provide the constituents on the PDFs,
the W and the Z both on the identifiers to

28
00:02:29,820 --> 00:02:36,240
the Wk to new and the cDk to new new key
channels for the leptons or procedural

29
00:02:36,240 --> 00:02:44,400
rapidity greater should be greater than
two to 4.5 on the transverse momentum

30
00:02:44,430 --> 00:02:49,770
greater than 20. Under the fiducial
criteria required at least one jet will

31
00:02:49,770 --> 00:02:55,260
transfer some momentum which then 20 T and
the procedure liquidity in the range 2.2

32
00:02:55,260 --> 00:03:03,090
to 4.2. The jet is also required to be
separated by radius of 0.5 from the travel

33
00:03:03,090 --> 00:03:08,190
leptons produce the in the authenticate
the contributions to the sector the wi the

34
00:03:08,190 --> 00:03:13,740
jet samples are shown in the left of
clouds, the yard is determined by fittings

35
00:03:13,740 --> 00:03:21,510
on new solutions the distribution
securities is about 46% or purity of the Z

36
00:03:21,840 --> 00:03:27,690
at the Jet sample is determined to be
aborted 98% It is very hard. So, total

37
00:03:27,690 --> 00:03:33,750
cross section for W jet and the jet
production option the by summary or the

38
00:03:33,750 --> 00:03:39,360
measures core section in terms of jet
eater. The wt ratios and the W plus W men

39
00:03:39,360 --> 00:03:44,580
are symmetries are also determined. The
measurements are in good agreements with

40
00:03:44,610 --> 00:03:51,360
the theory predictions as the red plot
shows. x a measurement of the production

41
00:03:51,360 --> 00:03:56,790
cross section of z bosons. As a society
it's pretty intense using the demo and the

42
00:03:56,970 --> 00:04:03,450
electron final state. So, luminosity is
interesting ISIS is about 300 people or

43
00:04:03,720 --> 00:04:08,520
more speakers. So cross section is a
measure of the four leptons within this

44
00:04:08,520 --> 00:04:13,380
fiducial range. The inclusive the Busan
core sections for the case to the moon is

45
00:04:13,380 --> 00:04:19,590
about 200 people or two electrons that is
about 100 netic force taking the

46
00:04:19,590 --> 00:04:26,250
luminosity to the forecourt imitates this
two measurements are considered consistent

47
00:04:26,280 --> 00:04:33,540
at the level of one on one sigma and alene
are combined to get this result. As the

48
00:04:33,540 --> 00:04:37,800
second plot shows the integrated cross
section for both time you're anti

49
00:04:37,800 --> 00:04:42,660
electrons and estates in the fiduciary
acceptance as a function of the tables on

50
00:04:42,660 --> 00:04:47,760
rapidity. On compared to the theory
predictions, the differential cross

51
00:04:47,760 --> 00:04:52,140

momentum normalized the total total core

52
00:04:52,140 --> 00:04:57,480
sections are shown in the red plots. Just
says medical ascertains can be a marker a

00:04:57,480 --> 00:05:02,340
console console when these distributions
are Our eyes and the nose significance

54
00:05:02,340 --> 00:05:05,490
declarations are sitting between the data
and standard model.

55
00:05:07,949 --> 00:05:13,139
For the W boson production, I submitted a
measurement of the core section for W

56
00:05:13,139 --> 00:05:18,329
decay to a new using the data
corresponding to integrated the luminosity

57
00:05:18,539 --> 00:05:25,319
of tumors Finbar to Z, the electrons are
required to have more than 20 gV off the

58
00:05:25,319 --> 00:05:32,459
transverse momentum and in this pseudo
repetitive range, after all sections the

59
00:05:32,459 --> 00:05:39,539
purity is about 60%. The transverse
momentum distributions of the 42 side with

60
00:05:39,569 --> 00:05:45,899
the result of the fades or light as the
top right shows the signal years are

61
00:05:45,899 --> 00:05:52,139
determined by frequency the electron
transverse momentum distribution after all

62
00:05:52,139 --> 00:05:57,239
correction corrections that acts as an
efficiency, the differential w plus and

63
00:05:57,239 --> 00:06:03,479
the W manners cross section in beans of
eater at the The bottom left shows the

64
00:06:03,479 --> 00:06:08,939
bottom panel panel displays a series of
predictions divided by the measure of the

65
00:06:08,939 --> 00:06:15,329
core section, it could be seen that the
result is compatible with predictions and

66
00:06:15,329 --> 00:06:20,669
the interest analysis the production of W
bosons has also been started in the mutual

expectations either reprise into by the

70
00:06:36,839 --> 00:06:41,489
way the line could be seen by it's the
ratio of bronchial fraction has the

71
00:06:41,699 --> 00:06:47,429
precision that exists the opposite
termination of the Hadron Collider as well

72
00:06:47,429 --> 00:06:55,829
as measurements made as the law. This is
the latest electronic physics result in

73
00:06:55,829 --> 00:07:01,589
your CV set of forward theta K to total
production at t Corresponding to an

74
00:07:01,589 --> 00:07:07,559
integrated element of tombs Finbar, the
reconstruction of top hair candidates is

75
00:07:07,589 --> 00:07:13,559
performed in both electronic and the
hydronic decay model, most of the top Tom

76
00:07:13,859 --> 00:07:25,769
requiring at least one atonic model for
the top hair. This at least one laptop or

our use of the photo reconstruction. The

80
00:07:43,079 --> 00:07:50,639
backgrounds to the K total are mainly from
the city and the W. The GS are SMEs with

81
00:07:50,789 --> 00:07:56,399
data data driven methods. The environment
domestic environment meant mass

00:08:02,099 --> 00:08:10,679
gray hair. So, cross section the results
compared with the program state k tomeo

84
00:08:10,679 --> 00:08:17,579
and the E measurements inside the same
satin region at 30 entity as color shows

85
00:08:18,089 --> 00:08:25,679
the predictions from the theory models the
combined cross section is about 96 people

88
00:08:36,959 --> 00:08:42,179
uncertainties respectively. This result is
compatible with the next method in the

92
00:09:02,820 --> 00:09:08,790
okay the summary priority to finish next
move to the prospector of some electron

93
00:09:08,790 --> 00:09:14,370
physics in a third CB, the Ric mixing
angle is k parameters in the Standard

94
00:09:14,370 --> 00:09:19,800
Model our CB can make our competitive
measurements of the mid mixing angle in

95
00:09:19,800 --> 00:09:26,520
the air, because the forward backward or
symmetries increase as repetitive of the

96
00:09:26,520 --> 00:09:32,040
balls and increase them and the dilution
effects, which means the possibility of

97
00:09:32,040 --> 00:09:36,840
wrong directions determination could be
decreased in high iterations as the

98
00:09:36,840 --> 00:09:42,240
laughter plot shows, which means that the
course bondings systematical uncertainties

99
00:09:42,270 --> 00:09:48,720
is expected to be smaller in RCB. The
second plot shows the relative trend in

100
00:09:48,720 --> 00:09:53,400
the forward backward symmetry is
integrated over the for RCB acceptance

101
00:09:53,850 --> 00:09:59,970
from a shift in effective laptop.
Electronic makes angle also showing up

102
00:10:00,000 --> 00:10:05,670
I'll plot out a PDF acetates on the
forward backward century, the different to

103
00:10:05,670 --> 00:10:11,880
demo environments, mastery interest being
more sensitivity to PDF variations and

104
00:10:11,880 --> 00:10:17,220
others being most of the activity to
variations in the effective electronic

105
00:10:17,220 --> 00:10:24,900
mixing angle. So mixing so mixing angle
angles has been measured with our CB

106
00:10:24,900 --> 00:10:30,630
detector using the Raman data multiple
other shows or comparisons of the way we

107
00:10:30,630 --> 00:10:35,130
can mix the angle or it's out from the
different experiments to actually be

108
00:10:35,130 --> 00:10:40,110
result of course we always work our way
outrage and is one of the most the purse

109
00:10:40,260 --> 00:10:42,810
size measurement from the heart on
clatters.

110
00:10:44,820 --> 00:10:46,860
Five minutes ago just to let you know,

111
00:10:47,940 --> 00:10:53,190
okay, expanded acetate with the most 36
are surely enough to pull out the

112
00:10:53,190 --> 00:11:00,450
stratasys acetate is is expected to be
very small environment all under you drawn

113
00:11:00,750 --> 00:11:05,760
to Office metal consultants are statistic
limited. So, with the increase of the

114
00:11:05,760 --> 00:11:11,100
statistics, the systematical uncertainties
it also could be decreased. And with

115
00:11:11,130 --> 00:11:16,050
enough data to PDF root cause
uncertainties could be reduced to very

116
00:11:16,050 --> 00:11:22,380
small buildings are waiting. This means
that with a good control of other sources

117
00:11:22,380 --> 00:11:27,450
of uncertainties or measurement to
actually be using the full data set about

118
00:11:28,110 --> 00:11:34,830
300 inverse images from the bars can be
significant and more precise that so the

119
00:11:34,830 --> 00:11:41,310
combinations of the measurements are Atala
upon SRV and as on the corresponding to

120
00:11:41,310 --> 00:11:46,530
the latest that are see yellow report as
the red brother shows RCB has come has

121
00:11:46,800 --> 00:11:54,270
kindly come up with a Muslim very comic,
very process measurement of the mixing

122
00:11:54,270 --> 00:12:00,990
angles. Another important measurement to
electronic physics is W mathematics. So

123
00:12:00,990 --> 00:12:06,450
electronically cafe two predicts the Ws
with only a certain amino acid that is

124
00:12:06,450 --> 00:12:12,390
bad. So the best individuals measurements
now have uncertainties all about 20 years.

125
00:12:13,050 --> 00:12:19,470
And the plot shows the Mian transfers and
distributions peaks at off. Okay.

126
00:12:20,940 --> 00:12:21,480
Okay, sorry.

127
00:12:23,550 --> 00:12:28,500
So yeah, so Okay, I think I had skipped
last eyes

128
00:12:29,790 --> 00:12:34,950
run to an ISIS is imprecise that makes me
Ganga is measured by using the full

129
00:12:34,950 --> 00:12:39,390
angular distribution of the balls on the
case, because it contains more information

130
00:12:39,450 --> 00:12:43,830
and forward back or symmetry. And the
angular core efficiencies measurements is

131
00:12:43,830 --> 00:12:48,570
also ongoing. So a four is relative to the
weakness in Angular and the reason for it,

132
00:12:48,570 --> 00:12:53,820
we help with the process of understanding
of how to capture additional alignment is

133
00:12:53,820 --> 00:13:01,590
to perform offline but this additional
elements 35% improvement In the masculine

134
00:13:01,590 --> 00:13:06,660
resolution could be observed at the Red
Cross shows. Another important measurement

135
00:13:06,690 --> 00:13:12,240
in electronic physics is W mass
measurement. Yeah. Now, but now the best

136
00:13:12,240 --> 00:13:18,060
experimental stuff is about only certain.
And the plot shows the VR transfers and

137
00:13:18,180 --> 00:13:22,770
momentum distributions peaks at this
position but the distributions is a

138
00:13:22,770 --> 00:13:29,010
stronger influence vacuity promontory is
the W transverse momentum shape, the

139
00:13:29,010 --> 00:13:33,360
details, which has the lumbee considered
as a source of activity as a measurement

140
00:13:33,420 --> 00:13:38,370
data loss on the same as the W mass
measurement. ercp is ongoing for this

141
00:13:38,370 --> 00:13:44,580
measurement and CB has some advantages.
The first is to be permanent about to me

142
00:13:44,580 --> 00:13:48,930
with statistical precision, you don't want
to data the secondary the pattern

143
00:13:48,930 --> 00:13:54,450
distribution function, as it is with a
partially console in our age of FCB with

144
00:13:56,160 --> 00:14:00,450
our PDF activities can be tightly
constrained with a fade to the About

145
00:14:00,450 --> 00:14:05,520
crucial distribution interest versus
momentum and data, it is possible Is it

146
00:14:05,520 --> 00:14:10,800
possible to simultaneous constituents and
W transfer some shape and the faith Why is

147
00:14:10,980 --> 00:14:17,130
so mitigated acuity absentees? Okay? So
family or short summary actually perform

148
00:14:17,130 --> 00:14:22,440
the measurements of the actual rake in the
forward region of pivotal agents are

149
00:14:23,310 --> 00:14:28,410
explored by other experiments, that unit
surplus or CB could provide some unique

150
00:14:28,410 --> 00:14:33,030
test of the stand model and the
consequence to the PDFs, a lot of work

151
00:14:33,030 --> 00:14:37,680
that I put aside for new executive
management. That's all thank you.

152
00:14:39,600 --> 00:14:44,220
Thank you very much for the interesting
and insightful talk. We have time for some

153
00:14:44,220 --> 00:14:47,220
questions, so please raise your hands if
you if you have them.

154
00:14:51,270 --> 00:14:52,980
Hi, Alexa, do go ahead.

155
00:14:54,930 --> 00:14:59,610
Yeah, could you give a bit more details
about the key weighting techniques to

156
00:14:59,610 --> 00:15:01,590
register PDF print certainties

157
00:15:01,620 --> 00:15:04,500
are the sons creditor, please?

158
00:15:06,480 --> 00:15:13,170
You mean that? Yes. Okay.

159
00:15:18,510 --> 00:15:19,350
So

160
00:15:23,430 --> 00:15:30,600
I think I think early on can give me your
help about introduction of religions

161
00:15:30,600 --> 00:15:31,170
technic,

162
00:15:31,650 --> 00:15:34,230
I mean only if you want me to I can say a
few words here.

163
00:15:35,550 --> 00:15:36,270
The

164
00:15:37,320 --> 00:15:42,390
so the solid black line is the PDF
uncertainty from current knowledge. So

165
00:15:42,390 --> 00:15:45,090
that's all measurements to date. And
here's what you get if you just do that in

166
00:15:45,090 --> 00:15:51,030
PDF 3.1. And that comes in at around 20
times 10 to the minus five. But of course,

167
00:15:51,060 --> 00:15:59,010
we know that you can look at the data
itself and ask which of the PDFs which are

168
00:15:59,010 --> 00:16:03,120
the PDF replicas in this case and then
PDF, agree best and you can look at the

169
00:16:03,120 --> 00:16:09,360
chi squared. And you can do this chi
squared weighting, which is of course very

170
00:16:09,360 --> 00:16:14,130
similar to what has been done by Atlas and
CMS with their on one measurements. And

171
00:16:14,130 --> 00:16:19,860
you can apply this and with this, you get
the open circle lines. And so you see that

172
00:16:19,860 --> 00:16:26,460
eventually with 300 inverse empty bomb,
which is the target of HCP with the

173
00:16:26,490 --> 00:16:33,210
proposed HCP upgrade to the uncertainty is
below 10 times 10 to the minus five, just

174
00:16:33,210 --> 00:16:38,820
using this free waiting. Now this is only
using statistical uncertainties within the

175
00:16:38,820 --> 00:16:45,090
study for the high lineal hc. So if there
were systematics those would obviously

176
00:16:45,090 --> 00:16:49,200
also need to be included the politicals
one of the key points is that going

177
00:16:49,200 --> 00:16:56,760
forward hcb you start with a PDF
uncertainty that is relatively small in

178
00:16:56,760 --> 00:17:00,240
comparison to the what you might see in
the central region. Because of that, This

179
00:17:00,240 --> 00:17:07,500
dilution factor is less of a penalty. And
so the actual work that's done by this re

180
00:17:07,500 --> 00:17:12,870
weighting in reducing the uncertainty is
is is smaller at HCV as well.

181
00:17:16,230 --> 00:17:21,540
Okay, thanks average. If I may ask your
question actually asked the same question

182
00:17:21,540 --> 00:17:25,500
right. So what is the like 12 right, what
is the timeline? Or is there a timeline

183
00:17:25,500 --> 00:17:31,200
for an interdimensional? I mean all these
all these generated studies in fantastical

184
00:17:31,200 --> 00:17:31,530
of them

185
00:17:42,870 --> 00:17:43,590
so

186
00:17:45,270 --> 00:17:48,330
yeah, that's like 12 you talk about the
battery mass measurements and

187
00:17:50,130 --> 00:17:54,420
I mean, these these studies have shown in
the past regenerate studies have shown in

188
00:17:54,420 --> 00:17:56,160
the past, there has been a massive benefit
of

189
00:17:57,900 --> 00:17:58,560
pre commitment

190
00:18:00,000 --> 00:18:02,970
And just wondering if there's a there's a
timeline for that.

191
00:18:04,799 --> 00:18:07,169
Coming from CMS, I wonder if there's gonna
be first

192
00:18:08,730 --> 00:18:09,630
and second serve.

193
00:18:18,180 --> 00:18:24,180
mainland. Do you want to comment on that?
Or do you want me to? Okay.

194
00:18:25,200 --> 00:18:29,130
Yeah, so the studies are ongoing. I think
it's similar to what you said your

195
00:18:29,160 --> 00:18:35,220
yourself that I think putting a time
timescale on it now is I don't want to be

196
00:18:35,310 --> 00:18:39,810
held to an optimistic timescale. But the
studies are ongoing. We are actively

197
00:18:39,810 --> 00:18:42,360
working on it. Okay.

198
00:18:46,020 --> 00:18:49,590
This CD are good enough. Can I also ask
the question

199
00:18:52,470 --> 00:18:55,980
on slide 11.

200
00:18:56,430 --> 00:19:02,340
You see here the full length or
distribution of this ebook And contains

201
00:19:02,340 --> 00:19:09,990
more information than the forward backward
symmetry. The long did this the case but

202
00:19:10,500 --> 00:19:14,520
which coefficient says are you about to
measure?

203
00:19:17,039 --> 00:19:22,619
You mean the Angular CLI finances? We also
use it to take care of

204
00:19:25,110 --> 00:19:32,280
Yeah, I mean, how many efficiencies Are
you going to measure like first flow for

205
00:19:36,180 --> 00:19:43,710
you until now we just calculated is zero
to a four by two we can also measures a

206
00:19:43,710 --> 00:19:48,480
zero to a seven Yeah.

207
00:19:50,040 --> 00:19:50,700
Thank you.
