STAR Flow, Chirality and Vorticity PWG

[Gavin Wilks <gwilks3 AT uic.edu>]

Dear Subhash,

I have addressed the comments and have re-uploaded to drupal. Here are the details of my updates:

slide#5: You can mention: For the first time, a large positive global spin alignment ... at mid-central collisions

slide#8: Seems redundant. You can combine 8&9 and indicate the expected improvement for BES-II.

I have made these changes.

slide#13: You can refer to this recent arXiv posting on the expected pT dependence from this phi field model: https://nam04.safelinks.protection.outlook.com/?url="https%3A%2F%2Farxiv.org%2Fabs%2F2205.15689&amp;data=05%7C01%7Cgwilks3%40groute.uic.edu%7C59b0683a3a964d500ffd08da490466c2%7Ce202cd477a564baa99e3e3b71a7c77dd%7C0%7C0%7C637902580511632170%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&amp;sdata=3WV%2F2oMgAxb3UL%2BZTGa6yFVySgKsCaUzV3wcEGI6ha4%3D&amp;reserved=0 (Figure 2)

Now slide #12: I referenced this arXiv figure at the bottom of the text box.

slide#14: Can you indicate the model fit is through BES-I data, may be you can also change the color of the fitted line same as BES-I to reflect that.

Now slide #13: I changed the color of the line to black to match the points and the legend now specifies “(Fit to BES-I only)”.

slide#15: You mentioned that it is supported by vector meson strong force field, which is fine. But in view of recent comments that we received from the Nature referee, it would be good if you could also indicate that more inputs from theory calculations are needed or something along that line. So that it sounds STAR doesn't imply that it is the only possible explanation.

Now slide #14: I added “More inputs needed from theory”.

Thank you and Regards,

Gavin

Dear Gavin,

Thanks for addressing my comments. I have a few additional suggestions:

I am fine with your presentation once you addressed the above comments.

Thanks and regards,

Dear Subhash,
Thank you for the comments on my sQM slides. I have addressed these
comments and uploaded the new copy to drupal.

slide#14: Does the model fit include BES-II data?

No, the model fit is just to the BES-I data.
Also, I have updated the values for the event counts from BES-II using
the most updated version of the BUR for runs 23-25.
Thank you and Regards,
Gavin

Dear Gavin,
Nice slides. I have a few suggestions for your consideration.
Title: you can probably mention either RHIC BES-II or STAR BES-II
slide#5: seen --> observed
"conventional physical mechanisms" --> conventional physics mechanisms or, conventional
polarization mechanisms.
"phi meson vector strong force field." --> phi meson strong force field or vector meson strong force field.
slide#7: "Polarization in late stage of hadronic interactions" --> Different late stage of hadronic interactions. Because I think hadronic re-scattering can destroy the polarization signal.
"Correlations between d and s-bar fluctuating vector meson fields .... " --> fluctuating vector meson fields for d and s-bar are expected to be weaker than s and s-bar
slide#8: Remove validate BES-I. We should stress what are the improvements at BES-II than BES-I, e.g. increased statistics, better event plane resolution etc. Also later in your slides mention as a future outlook that we can increase kinematic coverage in BES-II.
slide#9: Double check the number of events from our recent BUR.
"Improvements to STAR" --> can you be specific here, increased acceptance, statistics etc.
slide#11: Mention Run-2019 inside Figure.
slide#12: "Correct yields using efficiency calculated from STAR detector and Pythia6 simulations." --> Correct yields using efficiency calculated from STAR detector simulations. We probably don't need Pythia6, since it is techical part of analysis.
Check the prime symbols after "A" and "B" in the first bullet of right box.
"is set by simulation" --> is determined by simulation
slide#13: Space between 19.6 & GeV. Inside figure mention data taking year, rapidity acceptance.
slide#14: Does the model fit include BES-II data?
slide#15: "Consistent with BES-I results." --> Stress on the improvement than consistent.
slide#17: You can remove this since you don't have any backups here.
Thanks and regards,
Subhash
