STAR Flow, Chirality and Vorticity PWG

[付曈 <futong626 AT mail.sdu.edu.cn>]

Dear Conveners,

I am writing to follow up on the status of our request for the PWGC review of the analysis titled "Global polarization of Lambda and anti-Lambda hyperons in Au+Au collisions from the RHIC Beam Energy Scan-II." It has been about a month since our initial request. Could you kindly provide an update on the current status and an estimated timeline for the review?

Thank you very much for your time and assistance.

Best regards,
Tong

Dear Conveners,

If there are no further comments, we would like to request the PWGC review for the analysis of "Global polarization of Lambda and anti-Lambda hyperons in Au+Au collisions from the RHIC Beam Energy Scan-II."

And please find the paper proposal website: https://drupal.star.bnl.gov/STAR/blog/futong/Paper-proposal-Measurements-global-polarization-Lambda-hyperons-AuAu-collisions-RHIC-B-0

Best regards,
Tong

Dear All,

Thank you for your valuable comments.

1. Based on your suggestions, we have included an additional figure in the paper showing the dependence of Lambda polarization on |y_Lambda|. We have also added theoretical curves (Zuo-Tang Liang et al. 2021 Chinese Phys. C 45 014102, Fig. 13c) to this plot. Please find at link: https://drupal.star.bnl.gov/STAR/system/files/Fig5_3.pdf

2. Regarding the plot of energy dependence of global polarization, based on the latest theoretical developments, we plan to include two new theoretical models. Please find at link: https://drupal.star.bnl.gov/STAR/system/files/Fig2_8.pdf

3. As for the splitting of polarization between Lambda and Lambda-bar, we found that using a constant fit across the seven BES-II data points from 7.7 to 27 GeV gives P_0 = 0.134 +/- 0.061, with Chi2/NDF = 3.413/6. Applying a linear polynomial fit (P_0 + P_1 * x) yields P_0 = 0.286 +/- 0.211 and P_1 = -0.008 +/- 0.011, with Chi2/NDF = 2.853/5. For a constant fit using all BES-I and BES-II points from 7.7 to 27 GeV, we obtained P_0 = 0.144 +/- 0.06, with Chi2/NDF = 2.822/6.

4. As for the lower limit on the magnetic field, it is zero for all energies(95.4% confidence level).

Other comments are welcome.

Best regards,  
Tong

Dear convener and all,

I would like to first provide an update on the rapidity dependence of global polarization results, followed by a paper proposal on the global polarization of Lambda hyperons from BES-II.

Please add me to the agenda. I will send the slides later. Thanks.

Best regards,  
Tong Fu
