STAR Flow, Chirality and Vorticity PWG

Dear Chunjian

Very nice results!

In order for you to think about some possible answers in advance, I would like to send 

a few more questions for the meeting tomorrow (tonight for me). 

1. You do have two variables for pT variance (variance and reduced one), while you 

have only one dynamical variance for v2, which is pre-determined by the difference 

between 2- and 4-particle cumulants, have you tried to use other v2 variance definitions? 

My real question is whether this is the best normalization variable? What happens 

if we define this as same as the one for pT variance? 

2. You’ve shown the standard and sub-event result comparisons in Fig.6. Although 

one might expect and you also mentioned that this is a better with sub-event especially 

for peripheral, but you have chosen the standard one for the final plots, which might be 

understandable because of the better statical significance. But anyway, I do agree it 

would not matter much for this data, though. 

3. I would still like to see some closure test starting from some model with detector 

filters including acceptance and efficiency, which I hope you could show us sometime 

in the future before your final publication. 

4. You labeled “two centrality definition”, however I would think this is done with 

one centrality definition but presented in two different ways: Nch and centrality. 

I would also like to see if you could plot as a function of ZDC energy, for example, 

where we trigger on the ultra central events, or "refMult vs BBC” centrality comparison. 

Best regards, ShinIchi
