1) Paper preview: Measurements of H3L and H4L Lifetime and Production Yield in sNN =3 GeV Au+Au Collisions at RHIC
- Brief introduction from the PWG conveners (5’) [Dan Cebra]
- Paper proposal (15')  [Presentation by Yue-Hang Leung]
- Open discussions (35')
- Summary from the conveners' panel (5’)
2) APS meeting: 
- Please comment and approve presentations from PWG
- New preliminary results from JetCorr using Isobar data: SLIDES

Conclusion: there is no objection in releasing the new preliminary results based on combined Isobar data from JetCorr. 


3) What to run if there is one week left this year? The chance is quite small though. 

Conclusion: conveners will bring to PWG members' attention. Any proposal should be first discussed within the PWG. 

4) Shall we save only hlt-allvtx triggers for BES-II production?

Conclusion: the suggested method is not supported by PWGs, given the potential bias for peripheral events and small gain in resources. All the recorded events should be produced. 

5) Vertex selection for BES-II PicoDst 

Conclusion: the default vertex should be selected for PicoDst. 

6) eTOF calibration for 14.5 GeV: good performance up to day 118, and only one sector fully functional afterwards

Conclusion: PWGs are fine with having calibrated eTOF data up to day 118. Will not use eTOF data after day 118. 

7) Do we want to run eTOF in 2022 (pp 510 GeV)? What is the physics motivation? 

Conclusion: no physics motivation brought up so far. Cold QCD will discuss this item at the upcoming weekly meeting. 

8) Acknowledgement of old STAR preliminary results in a STAR talk

Conclusion: for any STAR preliminary results presented in a STAR talk, it is required not to associate it with a particular name, either the main analyzer or the person who presented these results the first time. These are STAR resutls, and anyone can present and defend them. On the other hand, the conference information where these preliminary result were firstly shown can be added if desirable. 

9) FCV: propose to produce Run19 200 GeV data

Conclusion: this dataset is already on the priority list, and we will revisit this once the TPC calibration is ready, and BES-II data production starts.
