STAR Flow, Chirality and Vorticity PWG

[ASHIK IKBAL <ashikhep AT gmail.com>]

Dear Subhash,

Thanks for your nice comments. I have taken care of them in the new version: https://drupal.star.bnl.gov/STAR/node/58864

Here are my replies inline:

"...complicated by the low magnitude of directed flow..." --> It is true
for mid-rapidity or higher beam energy, right? Can you be specific in
the abstract.

>> Mentioned this in the new version.

" e.g., v1(Ω−(sss)) − v1(Ω¯ +(¯ss¯s¯))," --> This is under the
assumption s and s-bar have same v1, right?

>> Actually, I tried to show an example here of how we can compare the different produced particles. The Ω−(sss) − Ω¯ +(¯ss¯s¯) is the simplest one to show, since only two particles are involved here. We don't have to assume that the s and s-bar have the same v1. If they have same v1, then v1(Ω−(sss)) − v1(Ω¯ +(¯ss¯s¯)) should be estimated as zero, as per coalescence sum rule. But this is not the case. We measured this and a non-zero splitting (Delta q = 2, Delta S = 6) is observed. 

"We measure v1 as a function of rapidity; and then ∆q and ∆S dependence
of v1..." --> First, we measure v1 as a function of rapidity; and then
we estimate ∆q and ∆S dependence of v1...

Thanks,

I sign off once you address them.

Thanks and regards,
