STAR Flow, Chirality and Vorticity PWG

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

Hi CW,

I am interested in this inv-mass method, maybe because I am doing the 
J/psi spin alignment analysis. So I recalled myself today your 
presentation, and I found I have a terrible memory. Could you explain 
again why/how the fitting function f in slide 4 is derived? and why 
<cos^2 theta*> = (1+\rho_fit)/3 ?

Thank you!

Diyu
