STAR Flow, Chirality and Vorticity PWG

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

Dear Xiaoyu

I could sign off your nice talk, but you have not discussed this in the 

PWG yet, so it would be nice that you could have shown us before. 

P7-8 : The statistical errors are invisible, but do you know why the difference 

between track(pure sim) and hit(including geant) is suddenly increasing at

|eta|>4. Are they a strong detector effect from a large dE/dx from spectator?

You use the true R.P. angle for both cases, is this geant simulation done 

taking a full AuAu event of UrQMD or taking a single track from the UrQMD 

event one by one? 

P9-10 : Do you like your data plots to be approved as preliminary even with 

the uncorrected data? (for E.P. resolution and BG and detector effects) 

If you insist to show these, I would at least label them more clearly that this 

is uncorrected for many possible other effects, not just for R.P. resolution) 

If you like to explain your analysis methods in detail, you would not need to 

use the experimental data, but can be done more with UrQMD data. It seems 

we do see a strong spectator contributions in both v1 and v2 (and most-likely 

in dN/deta distribution as well) in data, but you can not really defend what 

this is just with uncorrected data, so I wonder what we can say with these 

plots. 

Best regards, ShinIchi

Hi, xiaoyu,

Here is my comments for sign off

cheers,

Jiangyong

P1: please add "for the STAR Collaboration" and only keep your name

P2: For outline consider avoiding technical terms such as "nMIP" and StEpdFastSim in

P4: I would swap the order the two sub-bullet of the nMIP

P5: Fit to extract "the probability of 1-2..k-MIP events" in bin j

P6: please indicate the AuAu 27 GeV on this figure and also other figures where appropriate.

resolution correction --> correct for the event plane resolution

P7: StEpdFastSim--> EPD fast simulation

same format as in the STAR offline data.

a random point on the tile--> do you mean the center of the tile?

P8: ring one--> the inner-most ring

 to correct for the measurement-->to account for residual detector effects

The plots have been symmetrized around y=0, if so please indicate that

P10: please add some statement on this slide

Plots on P8-P10 should have proper x- and y-axis labels

P11: we developed a new method
