STAR Flow, Chirality and Vorticity PWG

[dshen <dshen AT rcf.rhic.bnl.gov>]

Dear Conveners and all,

Please find the slides for our updates via link below:
https://drupal.star.bnl.gov/STAR/system/files/Updates%20on%20paper%20proposal%20II.pdf

We also prepared a draft of analysis note for your reference:
https://drupal.star.bnl.gov/STAR/system/files/main_11.pdf

This update mainly focus on addressing the comments collected in my last 
presentation.
Just a quick reminder, those comments are:

General recommendation:
Combine relevant items from various presentation materials and prepare
a document with analysis details in one place and share with FCV. This
will help focus our discussion, help experts to pinpoint their
comments and save time for PAs and everyone. Also, this document can
eventually metamorphose into the analysis note. While making further
materials please consider addressing the following points, maybe make
small notes on the points.

i) Estimate Delta_v1 expected from coulomb interaction in peripheral 
collisions

ii) Address how to understand large Delta_v1 is seen for protons and
not for kaons and pions.

iii) It seems we see a difference in "Delta_v1" vs "y" between Au,
Zr+Ru species. How do we understand this system size dependence?

v) Consider adding differential v1 measurements, pt differential v1,
v1 separately for Zr+Zr and Ru+Ru species (if statistics is not enough
can consider two pt bins for example). If <pT> values are different
between different species it will be good to show the pT dependence
for each species even with two pt bins.

vi) Is it possible to estimate the relative contribution of
transported quark in Delta_v1?

vii) Consider a model calculation w/o EM field (e.g. UrQMD, AMPT) to
strengthen the point that the centrality dependent sign change cannot
be reproduced by non EM-field effects.

viii) Short summary for why PRX (250 words) will be useful. Usually
published along with paper. For now even a short para will be helpful
to move forward (e.g. during PWGC proposal).

Thanks,
Diyu
