STAR Flow, Chirality and Vorticity PWG

[Chunjian Zhang <chun-jian.zhang AT stonybrook.edu>]

Dear Shinlchi,

I could not find the plots that Sergei wanted to see in our earlier presentations 

in the PWG: the individual "normalized mean pt fluctuations of 2nd and 3rd order" 

for each species separately first before making ratio Ru/Zr. Please point us the location, 

Sure. No any problem. I will send the separate email with the slides for the plots that you and Sergei want. This is the email for replying you in advance. 

You were showing the correlation between vn and pT earlier, that you do not these days, 

are you still looking for these quantities also in isobar as well? 

We also looked at vn-pt correlations for isobars. I can also show them or present them in the FCV meeting. That’s ok to me. But what I want to point out is:

1)  three particle correlation needs more statistics in central. Even though isobar has 2B events, but it’s medium-system, so the Nch is small. Then we are still statical hungry. 

2)  Uranium is high-deformed system that’s why we can easy get the negative correlations for vn-Pt. However, Ru beta_2 is around 0.15 which is roughly same as Xe in LHC. That’s why we may also have no clear negative signal as what LHC XeXe shown. Also Zr beta_3 has some distortion. We need to be careful about this. I believe we try to understand them step-by step. I think shengli present vn-pt before for studying initial momentum corrections with dAu. Also 2021 runs has more dAu dataset for study this. So, Shengli may also want to converge this together. Anyway, we have all the calculations and we can talk it in the FCV meetings. 

Shengli used all dataset without corrected refmult. Also, he had the nice epd results, please find it in advance https://drupal.star.bnl.gov/STAR/system/files/FCV0406Shengli2.pdf

We will converge them using new corrected refmult. 

By the way, thank all of you for the nice discussion and comments.

Best regard,

Chunjian

if you have already shown us before. You might have shown for AuAu and UU only?

Dear Shinlchi and all,

I would like to discuss the comparison with CME draft and request preliminary plots for the upcoming DNP conference. The slides will be uploaded soon. Thank you.

Best regards

Dear Jiangyong, Prithwish and ShinIch,

I would like to give an update on;

1) The 2-particle momentum correlations

2) QA for new 19.6 GeV Run-21 Data

Thanks,
Niseem

Dear FCV PWG colleagues

We will have our weekly FCV PWG meeting on this Wednesday morning 29/Sep/2021
9:30AM in BNL (NY time zone) at our usual time and place. So if you have anything to
present, please let us know and please post your slide by Tuesday. The zoom room link,
ID and pass for the FCV PWG meeting are in our usual drupal agenda page below.
Please also keep in mind that all the preliminary plots should have already been there
in the summary area below.
Best regards, Jiangyong, Prithwish and ShinIchi
