STAR Flow, Chirality and Vorticity PWG

[Alexey Povarov <povarovas AT gmail.com>]

Dear Subhash,

I implemented your comments. You can find slides here:

https://drupal.star.bnl.gov/STAR/system/files/ASPovarov_NUCLEUS_2022_pres_ver4.pdf

Kaon data points were restricted to pT ~ 1.5 GeV/c  because we had some dispute about the PID method and got preliminary for this range.

I updated of comparison our own NCQ scaling results with those published. Slides attached below.

Best regards, 

Alexey

Dear Alexey,

Thanks for these comparison plots. It is not apple to apple as you have
a different centrality class. BTW, what is the reason for your kaon data
points to be restricted to pt ~ 1.5 GeV/c?

Please add x (and y) axis label on the left figures on slide 8.

Thanks and regards,
Subhash
