Hi, Ashik and all,

As both of us are interested in the v1 splitting, and we all got some interesting results, I want to bring out a discussion here.
Your analysis focus on the produced quarks via kinds of combinations of hadrons, you see violations of NCQ scaling and this violation increases with charge difference(\Delat q) and strangeness difference(\Delta S). 
I have no doubt about your analysis, but I want to discuss a little about the interpretations.
Although you given a sentence in the paper draft that \Delta q and \Delta S are inevitably correlated, but you imply the \Delta q is the dominate effect and trying to explain it by EM-field. 
When you do so, you imply the EM-field will introduce positive \Delta v1 slope between positive charges and negative charges, while the theoretical prediction is negative.
On another hand, our measurement shows the \Delta v1 slope between proton and anti-proton is negative, which is qualitatively consistent with theoretical calculations. 
So there is an apparent conflict, which should be avoided and understood before the publication.
From my point of view, if you want to argue the positive \Delta v1 slope is introduced by EM-field(\Delta q), you should fit \Delta q within a constant \Delta S. 

Best,
Diyu

Dear Conveners,

We would like to request for GPC of the analysis on "Electric charge and strangeness dependent directed flow splitting of produced quarks in Au+Au collisions".  We replied to all comments from FCV-PWG and PWGC. There are very minor updates of the results as per the comments from PWGC: 
1. Lower pT/nq cut is shifted from 0.1 to 0.13 GeV/c to get proton identification right. 
2. Only 5 independent combinations are shown in the plot of delta-v1 slope vs charge and delta-v1 slope vs strangeness.

Here are the details of the analysis, replies and the paper draft:


If there are no further comments/suggestions from the PWG, we wish to request for GPC.

Thanks,
Ashik (for the PAs')

Hi Prithwish, Shinilchi, all,

We were discussing at the FCV today about the STAR presentation (from FCV) for the upcoming DNP21 conference and I was told to share the agenda. Here is the information on the talks (by me, Niseem and Chunjian) from FCV group:

triangular flow of multistrange hadrons in Au+Au collision at 54.4 GeV.
