STAR Flow, Chirality and Vorticity PWG

Dear Fuqiang,

Thank you very much for your very valuable comments.

Here is the link to my updated poster: 
https://drupal.star.bnl.gov/STAR/presentations/Quark-Matter-2023/Directed-and-triangular-flow-identified-hadrons-and-light-nuclei-f-0

Here are some of the explanations:
The magnitude of pion also shows and increasing trend with rapidity (as 
shown in the figure 4: left side in red marker) but its is opposite 
direction because of shadowing effects at lower collision energies.

The proton v1 is measured over the range of 0.4 < pT < 2.0 GeV/c. In 
this measurement, the lower cutoffs of light nucleus pT are restricted 
to the same value in terms of pT/A (> 0.4 GeV/c). The pT upper limits 
are determined based on the pT versus y acceptances. We have tried to 
incorporate the maximum without compromising with the signal purity.

In order to extract the slope parameter(a) for every particle of 
interest we have used the 3rd order polynomial of form (ax+bx^3) and 
considered the other order functions in systematics. Fitting is done in 
range [y: 0,-1].


Please let me know if you have any further comments.

Thanks and regards,
Sharang
