STAR Flow, Chirality and Vorticity PWG

[Yicheng Feng <feng216 AT purdue.edu>]

Hi ShinIchi,

Thank you for your comments.

For the ~2sigma deviation in 50-60%,

I think I can mention this in the talk, as it is.

For safety, I prefer not to draw any conclusion from this single datapoint.

For the DN vs. a1+ and a1- separately,

I don't have the results for now, but I submitted jobs in RCF to get this information.

Hopefully, I could give an update in the coming PWG meeting this Wednesday.

For your question "Nobody have ever looked this in 200GeV AuAu, yet?",

For now, this analysis is only conducted in Run18AuAu27GeV. 

At 200 GeV the polarization is smaller so it may be difficult. 

But it doesn't hurt to look at 200 GeV data as well.

As instructed by you, I made a blog for my preliminary summary:

https://drupal.star.bnl.gov/STAR/blog/fengyich/dnp2020-preliminary-plots-ebye-corr-btw-lam-handedness-and-cme-run18auau27gev

including the slides and all the STAR preliminary plots (.jpg and .png).

I also updated the slides (EbyeCorrLamPolCME_DNP2020talk_YichengFeng_v3.pdf) to

https://drupal.star.bnl.gov/STAR/node/52374

There are only three small changes:

(1) backup removed, 

(2) "Run18, Au+Au, \sqrt{s_{NN}}=27GeV" added to all preliminary plots,

(3) The sequence in Eq.5 is rearranged (the first equal sign moved to the third).

Sincerely,

Yicheng

Dear Yicheng

After you prepare the preliminary summary page with all your preliminary plots to be linked 

at special drupal area for the preliminary location with necessary information at : 

https://drupal.star.bnl.gov/STAR/pwg/bulk-correlations/bulkcorr-preliminary-summary

then I would approve your talk. 

Best regards, ShinIchi

Dear Yicheng
I would sign off your nice talk with a few comments.

You have chosen to say no signal for both 10-50% and 0-80%,
which we all agree, but I would say there is one “2-sigma” signal
deviation point at 50-60%...

For your future PWG presentation, could you also please show
us just with Lambda (or anti-Lambda) as well as just with a+ (or
a-) in stead of Delta_a (a+ and a- combined), the signal could
be there in any of these covariances.

Nobody have ever looked this in 200GeV AuAu, yet?  
Best regards, ShinIchi
