STAR Flow, Chirality and Vorticity PWG

[Chunjian Zhang <chun-jian.zhang AT stonybrook.edu>]

Dear Subhash, 

Thank you for your kind comments. Please find the revised draft in 
https://drupal.star.bnl.gov/STAR/system/files/ICNFP_Proceeding_CZhang_v2.pdf

Please let me know if have further nice comments. thank you.

Done. Only two places, now I remove one.

I would like to keep the “New” to mention people this is the 1-2 years STAR 
results.

here the fundermental means “all possible direction in heavy-ion”.

done. revised it.

it’s not “it’s” or “its”. I would like to keep hydrodynamical. that’s 
different.

good suggestions. thank you.

one is good. two is too short for both.

remove this? …and … are different meaning. I would like to keep it.

remove first. FXT 4.5 is the first.

the trends of pi+ and pi-  are opposite.
