STAR Flow, Chirality and Vorticity PWG

[Prithwish Tribedy <ptribedy AT rcf.rhic.bnl.gov>]

Hello Yicheng,
 I sign off your nice abstract with one comment:

"While the ∆a1 variance measured via ∆γ = ⟨cos(ϕ1 + ϕ2 − 2Ψ)⟩ has not 
led to affirmative conclusion on the CME, covariance measurement between 
∆n and ∆a1 may reveal new insights"
-->
"While the ∆a1 variance measured via ∆γ = ⟨cos(ϕ1 + ϕ2 − 2Ψ)⟩ is 
designed to test the existence of CME, covariance measurement between ∆n 
and ∆a1 may reveal new insights on the phenomenon and on initial 
imbalance of chirality created in the medium."

(something along the line of this)


Best,
Prithwish
