STAR Flow, Chirality and Vorticity PWG

[Niseem <niseemmagdy AT yahoo.com>]

Hi ShinIchi,

Thanks for your email!

As you know life is not very start all the time so I do my best to get some of what you asked for.
Please find attached the plots for 10-30 central Au+Au at 200 GeV. This is related to what I will show at the APS.
When I have more time (since I'm changing house those days) I will send you more info as you asked.

Thanks,
Niseem

      Dear Niseem

I do not see any of the supporting analysis plots of your results here yet that you’ve promised…

Best regards, ShinIchi

Dear ShinIchi,

So sorry I did not see this email before.  I can do that in fast way for the normal R_2. I will need more time to create all of the requested plots. I will work on that now and hope to send you some plots very soon.

Thanks,
Niseem

Dear Niseem

I was hoping at least to see some of the answers to my earlier questions/requests 

(attached below) to your pwg presentation last week before approving your plots as 

preliminary for the APS presentation, but I did not see the answers, maybe I’ve missed?

I remember you have mentioned that you would be indicating your previous presentation 

and analysis notes for the possible answers that you could point-out. I would also think 

the step-by-step guidance of your analysis and correction procedures would also be 

appreciated and useful in the conference like APS, since people like to see what you 

really did. 

Best regards, ShinIchi

Dear Niseem

Thanks for the correct link in the chat window :

Thanks for the plots in our backup slides. 

Could you overlay 2 or 4 data sets from p19 in one plot (A), 

and show their relation to p20 in (B), then to p21 in (C), 

for both data and ampt side-by-side : (A,B,C) 3 plots x 2 case?

and for a few centrality cases and a few q2 selections? : 3 plots x (3+3) cases?

Maybe also for a few pT windows as you did in p12? : 3 plots x 3 cases?

And also for a few <Ach> window as you did in p16? : 3 plots x 3 cases?

And I would also like to see the analysis steps 

S -> S’ -> S” for both data and ampt                            : 3 plots x 3 cases?

Sorry to ask you too much, though. 

I would like to see these plots in order to understand the analysis better, 

which could also be helpful (or even used) for your APS/DNP talk? 

Best regards, ShinIchi

Hi Prithwish,
Thanks for your nice comments, please find my updated slides at the same link

https://drupal.star.bnl.gov/STAR/presentations/aps-april-meeting-2021/characterization-quadrupole-charge-separation-200-gev-implicati

>>slide#7 Mention how centrality was done.
I did not understand what you mean do i need to say that we do centrality by cutting on multiplicity?
For the AMPT data I'm using the a published plots which i added reference to it.


Thanks,
Niseem

Hello Niseem,   The slides look good. I have a few comments -- with these included I sign off.

Since you have new preliminary results please follow the STAR policy of making a page (if you haven't done so yet). Regarding the model plots, I would also request you to make the AMPT data available on RCF somewhere.

General comments:
1. I think we need to make a point that this analysis is promising and still in the exploratory phase as we need more time to explore the sensitivity to different background scenarios. Maybe some help from the theorists would be welcome. Also, isobar data may help to establish the efficacy of the observable. It would be great if you can add a few comments along these lines.

2. Please make sure not only every plot but each panel has a label saying either "STAR Preliminary" or "AMPT".

3. Put more details about the AMPT model on the slides. In particular, the version, link to publications wherever applicable.

Specific comments on the slides:

slide#4: "Prior/ongoing" --> "Prior"

 "make more discerning" --> "make a discerning"
slide#6: You need to define what "f" (or "f_q") is. What is the value of "f" on lower right plot ?
slide#7 "Run-11 data" --> "data from year 2011" Mention how centrality was done.

slide #8:
"The correlator response in " --> "The correlator response to" (this sounds better)

slide#9: Put the centrality for AMPT on this plot.
Slide#10:
Somewhere on this slide you need to put a quantitative statement. How about:
"Variation of q_2 leading to ~30% variation of v_2 in 10-30% centrality does not lead to any significant variation of R_{Ψ2}" ?

Slide#11:
Left plot inset requires more labels for x and y axes.

Slide#12:
This is the best place to put the comment on the exploratory nature of this study and add that more model  studies on sensitivity to background underway after the last bullet.

Best,
Prithwish
