STAR Flow, Chirality and Vorticity PWG

[Zhiwan Xu <zhiwanxu AT physics.ucla.edu>]

Hi Subhash,
 Thank you for the comments. I have updated a STAR logo on each slides.
 Please find the new version:

 AVFD and AMPT: The AMPT does not handle the coupling between v2 and momentum 
conservation and/or local charge conservation as well as AVFD. The ensembled 
average of dg112 measured with AMPT is much smaller than data or AVFD. AVFD 
has tuned the LCC to the experimental values, and as a hydro model it 
resonably well deals the momentum conservation. Therefore, to our 
understanding so far, AMPT can not fully represents the background in CME 
measurement. It still requires some further accessmenet.

 s#7 the number of events in BES-II is from my own cuts. Thank you for point 
that out, I will confirm with other BES-II measurements.

 s#8 the large statistic error mainly derives from a long-linear 
extrapoation, which is referring to the large gap between first data point 
and v2=0. I added an arrow pointing to the region on plot. Thank you for 
catching that.


Best,
Zhiwan

Dear Zhiwan,

Very well polished slides. I have only a few comments/suggestions for 
your consideration:

General: we usually keep a star logo in the corner of each slide or 
mention STAR in each slides. But it's up to you.

s#3: 1st bullet v_2 and in other slides # 11

s#6: Could you help me understand why the ESS method works for AVFD, but 
not for AMPT?

s#7: Please make sure number of events are consistent with other QM 
talks or mention analyzed events or accepted good events.

s#8: I don't understand the first bullet. What drives large statistic 
error?

Thanks and regards,
Subhash
