STAR Flow, Chirality and Vorticity PWG

Hi, Han-Sheng :

Thanks for the clarification. So the invMass selection is not reflected in the final plot. It is a bit confusing as at one place we highlighted the advantage of the invMass technique but then later on the money plot we avoided of using it.  

But it is ok, I at least understand what you actually did.

Thanks,

Aihong

The ESE data point comes from the red point on the right-hand side plot (ZDC EP) on slide 8. The data point is the y-intercept over inclusive mass regions so we do not add invM cut on it.

The POIs are hadrons with assumed mass equal to pion mass because we have not applied any PID cuts on those tracks.

Thanks for your comments.

Best regards,

Han-Sheng

Comment:
Hi, Zhiwan/Han-sheng :
On slide 13, does the ESE have an invariant mass cut to select low invM
region ? If so, can we add the invM cut to the legend ?  Also, In the legend
shouldn't the "h-h" for ESE be labeled as "pi-pi" because you now calculate
invMass so I assume you analyze pions instead of charged hadrons. Similar
comment on slide 8 & 9.
Thanks,
Aihong
