Subject: [Star-gpc-355-l] Updates from higher statistics and corrected cuts for HIJING
Date: Fri, 7 Jul 2023 13:55:42 +0000

Hi GPC,

I want to report an update at the next GPC meeting.

For the current paper draft results, the HIJING quenching off statistics were marginal.

We have now accumulated significantly more statistics.

This resulted in some small numerical changes.

For the HIJING results in the current paper draft, we did not apply \Delta\eta_ab gap, and we used an incorrect \eta range for single particles.

Correcting those resulted in some small changes as well.

The biggest change is in the central value of Group-2 Subevent result, by about 0.5 sigma of statistical uncertainty.

The details of those updates can be found in the slides

In addition, in data analysis, the calibration is now done in a period-by-period manner as was done in the blind analysis.

This does not make any visible difference to the results.

Please let us know if you have any comments.

If you agree with the changes, we can quickly update the paper drafts.

Sincerely,

Yicheng for PAs
