STAR Flow, Chirality and Vorticity PWG

[ShinIchi Esumi <esumi.shinichi.gn AT u.tsukuba.ac.jp>]

Dear Chunjian
Thanks again for the detailed summary, and sorry to bother you with these 
E-mails several 
times, I had one more question that I’m always forgetting to ask you during 
your talk. Have 
you try to compare the results with RefMult2 (|eta|>0.5) or separating 
acceptances for the 
centrality from the measured region? Now your measurements are done within 
some 
overlapping eta acceptance in the mid-rapidity with centrality definition, 
right? This is not 
the multiplicity fluctuation, so the effect might be smaller than the 
net-number fluctuation 
studies, but we might like to know if there is any possible auto-correlation, 
which could also 
depend on the order of the cumulant), have you tried to look into this? 
Further studies 
including EPD could clarify more about the effect, as we see in some of 
Shengli’s slides 
with more eta-gap, though... 
Best regards, ShinIchi
