STAR Flow, Chirality and Vorticity PWG

[Jiangyong Jia <jiangyong.jia AT stonybrook.edu>]

Hi, Niseem,

The abstract looks very good. My only suggestion is to try align the
physics better with initial state of the Heavy ion collisions.

Right now you mainly talk about the final state, but I believe jet
tomography also constrains initial geometry (via the scaling relations) 

You might want to mention something about the scaling aspect and what
one can learn by comparing with LHC.

Other than this, I sign off.
