STAR Flow, Chirality and Vorticity PWG

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

Dear Jagbir
Sorry for the long delay, you have not shown the final results fCME 
or conclusion on how it does change with your selections with window size 
and asymmetry cut, that I would also like to see. I do see the sensitivity 
(resolution w.r.t. Psi2) does not change much with dumbbel window size, 
while it changes with the dumbbell asymmetry cut at least for the average. 
From your comment on p7 with fDb dependence, it seems you say it would 
be better with smaller dumbbel window size, but why? Can you say the 
sensitivity has really improved or the fluctuation has increased? Do you 
understand why the sin term deviate from zero (positive in central and 
negative in peripheral) that I’ve worried? This is also related to my another 
question why the distributions in p4 and p5 are deviating from -cos(2x) shape 
especially in central events? Does it help to flatten the Psi_DB distribution 
just like what you do for the Psi_EP as you show in p3. Could you also plot 
just Psi_DB distribution first without any subtraction (which should be 
flat)? 
When are you going to talk about these results in the PWG? What about 
the coming collaboration meeting in about a few weeks? 
Best regards, ShinIchi

PS : Are you planning to do this study with isobar data sets?  Since blind 
analysis is mostly over, so I guess you can also go ahead. I’m eagerly 
waiting to see your results there, too. Thanks again.
