Yan Huang:
dN/dy measurement for strange hadrons(|y|<0.5) and pions (|y|<0.1) are done in different rapidity ranges and therefore additional systematic error on strange/pi ratio need to be estimated.

https://drupal.star.bnl.gov/STAR/event/2021/01/04/lfs-upc-pwg-meeting

Hui Liu:  
There is a small discrepancy between Hui Liu and Ben Kimelman's results (proton yield), needs to be fixed. 

Ben Kimelman :
There is a issue in spectra fitting , working to fix this.

Matthew Harasty:
Feed-down correction has been done using UrQMD. There was a debate on the method of feed-down correction, data driven vs UrQMD.  

Zachary Sweger: 
Galuber model (with two component particle production) can not explain multiplicity distribution at 7.2 GeV FXT. Investigation is ongoing. 

Yue Hang Leung :
First look at the pT spectra of hyperhuclei at 3 GeV, FXT. Need to understand correction due to thickness of target. 

Wlodek Guryn:
paper proposal on Elastic cross-sections in p-p collisions at 510 GeV. PWGC review very soon.

Minutes:
Presentation by 
Yue Hang Leung:
Rapidity cut <-0.3 is been used to minimise effect of mis-match between Embedding and Data inTPC Nhits distribution. 

Presentation by Dingwei Zhang:
Data driven feed down correction has been used and feed down correction found to be inconsistent with previously published results. Old feed down correction was based on UrQMD model (which under predict the measured lambda yield ?)

Presentation by 
Yan Huang:

Suggested to check phi/pi ratio.

2020/12/14:
https://drupal.star.bnl.gov/STAR/event/2020/12/14/lfs-upc-pwg-meeting

Minutes:

 
Presentation by Hui Liu
 1) Need to show comparison of proton analysis with Ben Kimelman
 2) Systematic from different fit functions are shown, systematic due to tracks cuts need to be evaluated. 

Presentation by Maksym Zyzak:
1) Bad runs need to be removed ( 3.85 GeV data)
2) Is the lifetime of hyper-nuclei consistent with the LBL group (Yue Hang)?
3) Topology cuts tuning? : Manual 

Presentation  by Kong Tu:
1) Chi-square fit has been used for yield extraction, suggested to cross-check the results using the log-likelihood method.
2)  only statistics errors are shown on the cross-section ( systematic needs to be evaluated )

3) Expected PWGC preview: January 2021

1. QM readiness:
- dielectron (Shuai)

1. Current status: The UU@193GeV (MB trigger) di-electron analysis is

basically done, and the proposed physics plots have been already generated.

2. The parts not finished yet: The systematic uncertainty of hadron

contamination (will be done in one week); make the physics plots in good

shape.

3. Results I intend to show:

http://www.star.bnl.gov/protected/lfspectra/syang/conference/QM2015/Proposed_plots_for_QM.pdf

- Jet quenching S parameter (Stephen)
- Rapidity density at BES (Chris)
