STAR Flow, Chirality and Vorticity PWG

[Shengli Huang <shengli.huang AT stonybrook.edu>]

Dear ShinChi,

    I have no idea for the task force but I think you are in the task force. I am still finalizing the paper draft now. So once it is done. I will request for the pwgc review. Sorry for the waiting, COV-19 really ate most part of my time.

Thanks!

Dear Shengli

I see. The sub-nucleon structure would be there in all the case, but the 

nucleon fluctuation is getting dominant in dAu and 3HeAu cases, so I can 

also agree. Then it’s now getting closer to the phenix conclusion then, I 

thought you were saying more about multiplicity rather than the geometry 

from star side, or? I’m open to both cases, which is in deed interesting. 

Could you remind me your publication status on this? I thought we were 

forming some task forces to resolve these issues between the experiments, 

do you know about that as well? By the way, one of our student Yuri from 

Tsukuba has started to looking into dAu, so let’s see what she would say 

in the PWG, hopefully very soon... 

Best regards, ShinIchi

Dear ShiniChi,

    Even with sub-nucleon fluctuation, the eccentricity in centrally dAu will be 20% larger than pAu. So the multiplicity will not be the only reason for the flow difference between these three small systems.

    There is no energy dependence between RHIC and LHC even in large system while the <Nch> can be a factor of 5 difference. 

Thanks

Dear Shengli

I thought your results could be explained by a general multiplicity

trend from pA -> dA -> 3HeA? Therefore I was wondering why you

need (or like) to say “pA” is similar to LHC, I just like to know what 

is special on pA and/or different from dA and 3HeA...

Best regards, ShinIchi

Dear ShinIshi,

     I am a little confused about you second comments. Similar to pPb is by comparison which we show in BUR. But we do not say p/d/He are similar.

Dear Shengli
I can also sign off your nice abstract with a few comments below.
You say the results are not sensitive to the methods, but I understood
that you’ve selected the methods based on the consistency of the results.
Is your pAu qualitatively different from dAu and 3HeAu? I’m asking this
because you say it's similar to pPb at LHC…
Best regards, ShinIchi
