Hi Sevil,

Those will also be a background source (any known physics that contributes to the OS-SS difference will be background). The physics nature of the background isn’t important to the analysis. One doesn’t need/want to quantify each possible individual background source; that wouldn’t be robust. We try to use data wherever possible to assess nonflow effect, and where we cannot, we try to assess a conservative syst uncertainty. 

Best regards,
Fuqiang

Thank you Jamie,
Also to follow up on the 3p correlation vs 2p correlations estimate, is there any study that you can point to the effect of 3 particle decay of a resonance of which only 2 same sign are measured due to in efficiency/acceptance of the detector  (ex: sigma(1385)—> lambda+pi—>proton+pi(-)+pi but only proton and pi) and repeat the same for the positive charge. It can be that there is no correlation remaining for the 2 of the 3 particles, but do we know that?

Notes from first meeting:
May 23, 2023

Prithwish gave a background on history in PWG.

Sevil: as a bit of an outside observer of the CME world questioning why the PRL is necessary

Answer (Prithwish, Yicheng)
is that the community is expecting a compact answer
to the isobar data; no PRL yet.  This would give that with
an explainable upper limit.  

Conclusion: the PRL needs to be crafted to make that clear.

Yu and Jamie:
    On the baseline plot: either show with all 12 datapoints of original PRC plot or only the
    four datapoints for which the baseline is found.  The current
    mixture of showing 7 of the measurements of which 4 have a baseline
    is confusing.

Yu:
    Feels the short paper needs some work on the general audience side
   
    Group names: drop individual group names and stick to Group 1,2, etc.

Ankita:
    Started looking at the code and the analysis note.
    Read the analysis note.  Yu and Ankita will discuss separately.

Sevil:
    Question about 2-particle correlation: OS-SS assumes all resonances
    are neutral.  What about the effect of charged resonances?
    (Yu stated that most 2 particle correlations are from neutrals like
     the rho.
     But following up: Delta++?  Are there model studies that show that this
     method gets all 2 particle correlations?)
    This needs a followup, maybe a model analysis.

Yu:
    Question about upper limit: very specifically on Ru.
    Slightly different for Zr.  Needs to be a bit clearer in the
    paper, which doesn't mention Zr at all.

Meet again in 2 weeks.  In the meantime please send a full first
round of comments to the list.

Dear Jamie, and All,

As you may know Yicheng and I are taking STAR shift for this and the next week. I'm on the day shift, he is on the night shift. And I will be on travel until 25th.
I think since I followed most of his work in the CME group meeting, and it is the first GPC meeting, please feel free to hold the meeting next week if everyone else is available.
I'll try to join if the shift is less busy, or if you can take a record, I can follow up after the meeting by the record video and email.

Thank you.
Best,
Yu

Dear All,

Thank you all for agreeing to serve on this committee.
I've set up a when2meet at 
for the next 2 weeks for an inaugural meeting.  Please fill that out
when you can.  I'd prefer a first meeting next week if possible.

Thanks,

Dear Jamie, Yu, Sevil, Ankita, Prithwish, Yicheng,

Thank you for agreeing to serve on the God Parent Committee (GPC) for the new STAR paper. The committee members are:
=========================
Chairperson: James Dunlop
Member(s) at large: Yu Hu
Member for English/Grammar QA: Sevil Salur
Member for Code QA: Ankita Nain
PWG representative: Prithwish Tribedy
PA representative: Yicheng Feng

Information on the STAR paper to be reviewed by the GPC :
=========================
Paper title: Estimate of Background Baseline and Upper Limit on the Chiral Magnetic Effect in Isobar Collisions at $sqrt{s_{NN}}$=200 GeV at the BNL Relativistic Heavy-Ion Collider
 
PAs: Yicheng Feng, Fuqiang Wang
 
Targeted journal: Phys. Rev. Lett (short version), Phys. Rev. C (long version)
 
 
Paper Manuscript: 
 
 
Code: $CVSROOT/offline/paper/psn0811
 
 
 
Charge to GPC: 
=========================
The GPC is requested to review the new STAR paper indicated above, and let STAR Management know when it is considered ready for review by STAR. The GPC should ensure that the presentation of the physics message and data is clear and impactful. It should take into account the logical flow and construction as well as the technical accuracy and correctness of the analysis. 
 
Please note that a dedicated mailing list (https://lists.bnl.gov/mailman/listinfo/star-gpc-355-l) has been created for this GPC, and all the PAs and GPC members have been subscribed. Please use this mailing list for all GPC communications, which will be archived automatically.
 
When the GPC Chair writes to the PAC/Spokespeople to ask for release to the collaboration review. The PAC/Spokespeople will download acknowledgements, and send to the PAs for inclusion into the paper draft. "The STAR Collaboration" will be used as the author. The PAs and GPC should not be using an author list up to that point.
 
It is highly recommended that PAs prepare YAML data tables to be uploaded to HepData before the paper is announced to RHIC. Instructions on preparing YAML tables can be found here: https://drupal.star.bnl.gov/STAR/blog/marr/instructions-hepdata-submission. 
 
More information about the paper submission procedure can be found here: https://www.star.bnl.gov/central/collaboration/authors/
 
 
Guidance to GPC :
=========================
Guidance for the GPC process is described in the STAR publication policy item 14.
 
The Technical Notes and codes should be revised as necessary during the GPC process. The purpose of the STAR Technical note accompanying every paper is to describe the analysis, data and methods used, and all necessary background information. This would then allow each collaboration member, if desired, to repeat the analysis at a later time in the exact same fashion and reproduce the results published. A member in the GPC is assigned the responsibility to check, in discussion with PAs, if the analysis code compiles and processes the designated data set. When the paper is released by the GPC to the spokesperson for next steps towards publication, the PA's, in agreement with the GPC chair, are required to provide a note on the changes made to the Technical Note if any and the code check has been satisfactorily completed.
 
The manuscript recommended to the collaboration by the GPC should be a finished, sound, grammatically correct scientific publication ready for journal submission aside from final comments and tuning by the Collaboration at large. The GPC is requested to ensure that when the manuscript is released to management it should have the latest author list of STAR Collaboration, obtainable from the STAR web page and the latest acknowledgments.
 
It is presumed that most of your work can be carried out through email correspondence and also by phone/SeeVogh/BlueJeans conferences. If you require a meeting or direct discussion with the principal authors, then that should be also possible. Once you are satisfied with the manuscript, then STAR Management should be informed and it will be announced to STAR that the paper is available for review and comments by STAR for a two week period. At or near the end of those two weeks, the principal authors will be asked to prepare a modified version which addresses suggested changes with a statement about those changes that they feel are not warranted. This latter statement can take place in the form of email responses as the comments from STAR arrive and should be logged for reference if questions arise later. The God Parent Committee or GPC Chair may be asked for final review of the revised version before journal submission if deemed necessary.
 

Thanks and Best regards,
Sooraj
