STAR Flow, Chirality and Vorticity PWG

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

Dear Niseem (and Chunjian)

I also sign off your nice abstract with one request to make the title more clear what is discussed 

in the talk, where the contents of your talk seems to be more focused on the rho and c2, which 

is somewhat different from Chunjian’s abstract is more focused on mean pt fluctuation, while the 

both title sounds very similar “transverse momentum correlation (or fluctuation)", so please include 

rho and c2 or please try to make a clearer distinction in the title in order to make both accepted 

as a talk. 

Best regards, ShinIchi

Hi Jiangyong,

Thanks for the nice comments.

Please find the updated abstract at the same link,

https://drupal.star.bnl.gov/STAR/node/53482

I think that both sets of results will guide the extraction of \eta/s. I rephrased the abstract to reflect the value of each set of measurements. 

Thanks,
Niseem

Hi, Niseem,

Nice abstract 

1. Please mention STAR in title

2. The scope of the abstract is quite broad, I would suggest you to focus on the C2(Δη,Δφ) in BES.  Since there might still be systematic checks to be done, for example how stable are the results if you vary the pair cuts, this aught to be one sources of uncertainty.  Also the vn-pT correlation is a bit distraction to your eta/s focus, I suggest you just show your previous prelim results. 

Cheers,

Jiangyong

For your comments,

It is not clear what this new observable is C2(Δη,Δφ) does not clearly indicate that you're measuring transverse momentum correlations. 
>> It's written that C2(Δη, Δφ) is the “longitudinal two-particle momentum correlations”


Do you think you'll be done with systematics by CPOD
>>The standard systematics i.e. tracks and events variations exist, currently along with others we are working on the systematics associated with the extraction of the \eta/s

I remember you looked at \rho for three energies: 
https://drupal.star.bnl.gov/STAR/system/files/Flow_PT_5.pdf 
Did you look at all other energies for 200-11.5 GeV, if not do you plan to update soon ? Or I missed it? 
>>I’m working on including some of the lower beam energies, however, I rephrased the sentence to reflect the energy range for the different measurements 

Thanks,
Niseem

Some general comments/question: 

It is not clear what this new observable is C2(Δη,Δφ) does not clearly indicate that you're measuring transverse momentum correlations.
