STAR Flow, Chirality and Vorticity PWG

[郗宝山 <xibaoshan AT sinap.ac.cn>]

Dear Prithwish,

Thanks for your nice comments.

We have made modifications to the abstract based on your comments.  At the same time, modifications were made based on the opinions of the Fudan group.  We upload the abstract of the new version to the original location.

Thank you very much.

Best,
Baoshan

主题: [Star-fcv-l] STAR presentation by Baoshan Xi for Quark Matter 2023 got commented by Prithwish Tribedy

Dear star-fcv-l AT lists.bnl.gov members,

Prithwish Tribedy ( ptribedy AT bnl.gov ) has commented on a material originally  
submitted by Baoshan Xi ( xibaoshan AT sinap.ac.cn ) at
https://drupal.star.bnl.gov/STAR/presentations/Quark-Matter-2023/New-Insights-Spin-Alignment-Heavy-Ion-Collisions-Measurements-phi-om

Comment:
Nice abstract! Here are my comments.

"The STAR collaboration recently discovered" -->"The STAR collaboration  
recently observed"


"in the first phase of the RHIC Beam Energy Scan program (BES-I)" -->
" in Au+Au collisions using the data from the first phase of the RHIC Beam  
Energy Scan program (BES-I)"

"may be accommodated by vector meson force fields."
-->
"may be attributable to the influence of vector meson force fields"

We should revise lines 10-12. Instead of referring to "higher precision data"  
from the BES-II program, we should use the term "higher statistics data". We  
should reserve the word "precision" for "measurements". Here is my  
suggestion:

"With higher precision data from the BES-II program, new measurements of  
$\phi$-meson global spin alignment as a function of transverse momentum,  
centrality, and rapidity in Au+Au collisions at $\sqrt{s_{NN}}$ = 7.7, 14.6,  
and 19.6 GeV will be presented."
-->
"In this contribution, new precision and differential measurements of  
$\phi$-meson global spin alignment as a function of transverse momentum  
($p_{T}$), centrality, and rapidity ($y$) at $\sqrt{s_{NN}}$ = 7.7, 14.6, and  
19.6 GeV will be presented, using higher-statistics data from the BES-II  
program."


line 15-16, let's make it a bit more clear:
"\We are presenting $\phi(s,\bar{s})$, $\omega(u,\bar{u}, d, \bar{d})$, and  
$J/\psi(c, \bar{c})$ together to understand the role of the strong field in  
nuclear structure and the evolution of nuclear matter."
-->
"A comparative study of the spin alignment of  $\phi(s,\bar{s})$,  
$\omega(u,\bar{u},d,\bar{d})$, and $J/\psi(c,\bar{c})$, will be presented.  
This study with vector mesons of various quark contents aims to understand  
the role of the strong field in nuclear structure and the evolution of  
nuclear matter."


"These species and decay channels measurements may help to disentangle..."
-->
"The addition of new species and measurements through previously unexplored  
decay channels may help to disentangle..."

I have to say the following part of the sentence is complex:
"...may help disentangle the effects of in-medium and hadronization  
mechanisms, guiding theoretical progress towards understanding global spin  
alignment intricacies."

How about changing 16-19 like this:
"The addition of new species and measurements through previously unexplored  
decay channels can help understand the intricate effects of in-medium and  
hadronization mechanisms on global spin alignment, advancing theoretical  
progress."


I don't think spin alignment can influence CME, it can influence the change  
separation, let's rewrite this as follows:

"Furthermore, the global spin alignment of $\rho^0$ mesons can effectively  
influence the measured Chiral Magnetic Effect (CME), which needs to be  
addressed for a clean interpretation of CME observables."
-->
"In addition, we show that the global spin alignment of $\rho^0$ mesons can  
effectively influence the measurement of charge separation across the  
reaction plane."

"Our results’ implication on the CME search will also be discussed in this  
talk."
-->
"The implications of our results for the search for the Chiral Magnetic  
Effect will be discussed"
