- Open discussions (35')
- Summary from the conveners' panel (5’)
 
Proposal page: https://drupal.star.bnl.gov/STAR/blog/tinglin/Paper-Proposal-2015-pp200-Endcap-Dijet-ALL-Measurement
PA: Ting Lin
Target journal: PRD

NOTES
 
2) Data production 
  • Production priority (LIST)
    • Treat O+O data with two polarities as two independent datasets in terms of calibration
  • Embedding - Run19 19.6 GeV TpcRS tuning (SLIDES)
    • nTimeBucket comparison, difference seen in data/MC, particularly for low pT tracks. Impact on efficiency is very small
    • nHits comparison looks reasonable. Some further tuning was done. 
    • Mostly ready to produce embedding samples for BES-II data. 
  • eTOF calibration
    • 7.7 GeV almost ready
    • 9.2/11.5 still running
    • Run20 FXT: clock jump issue largely improved. now overall 0.1% remaining contribution, two counters have <5%. Currently investigating the multiplicity dependence. 
  • BES-I MuDst->PicoDst conversion
    • AuAu62_production, P10ik
    • AuAu39_production P10ik
    • AuAu27_production_2011 P11id
    • AuAu19_production P11id
    • AuAu11_production P10ih
    • AuAu7_production P10ih
    • Chain option: picoDst PicoVtxMode:PicoVtxDefault PicoCovMtxMode:PicoCovMtxWrite PicoBEmcSmdMode:PicoBEmcSmdWrite
  • Run17 st_fms: new production with P22ib done
    • Can we remove MuDst and PicoDst of P18ic?
  • BES-II datasets are being duplicated (Progress)
Conclusions:
- Conveners agree with the current priority of producing 200 GeV d+Au and O+O data before other Run21 datasets given that quite a few groups are interested in analyzing these data for QM. 
- Run20 FXT data: the eTOF software coordinator is currently investigating the multiplicity dependence of the impact of the clock jump. Once done, we will summarize all the findings and caveats, and communicate with analyzers. 
- Run17 st_fms P18ic data can be removed from distributed disk

2) LRP white papers
Conclusions
- There are multiple white papers ongoing: i) one from the hot and cold QCD townhall; ii) one for hot QCD organized by conveners/speakers from townhall. It will be good to know which STAR members are on these writing committees for easier coordination. 
- It was suggested that the STAR white paper should focus on the future programs (what physics STAR can do in the next years). Summaries of what have been learnt since last LRP should be concise and about physics, not a laundry list of measurements. 
- Better to submit the STAR white paper to arXiv such that it can be cited. 
- The Nov. 7th deadline set by the townhall organizers for white paper submission is quite rushed. We should probably communicate with them about this. Cold QCD folks have already written to them. 
- Will continue the discussion in the next weeks. 

3) Follow up
  • Do we still need to duplicate small-size datasets on distributed disk?
  • List of key BES-II measurements: LIST
  • pwg_tasks space: usage
Conclusions: conveners will send feedbacks they received to the PWGC mailing list, and Rongrong will update the tables accordingly.

NOTES

2) Hot QCD Community White Paper
  • From Megan: "Jean-Francois and I were asked to organize a Hot QCD white paper that helps put the other white papers in context of the physics goals in our field. My understanding is that STAR was preparing to write a white paper but wanted to suggest that we join efforts and would like to invite those in STAR who were planning to contribute, to help write the relevant sections of the document we are preparing. Below is the draft outline of topics that we are planning to cover. We appreciate any recommendations you have for writers or any other suggestions on this process."
  • STAR members already in the committee: Xin Dong, Prithwish Tribedy, Jiangyong Jia, Kong Tu
Conclusions
- We will not write a separate STAR white paper. But instead, use the BUR as the reference for details.
- Will propose the following people to join the hot QCD community white paper writing committee: Rongrong Ma, Takafumi Niida, Dan Cebra, Nihar Sahoo

3) Data production news
  • DAQ proudction
    • Run17 pp 510 GeV st_fms with pp2pp option - done (0.5% remaining)
  • PicoDst -> MuDst conversion
    • Run17 pp 510 GeV st_physics - done
      • Is the jet tree production finished? Can we remove MuDst files from RCF?
    • Run12 UU 193 GeV - done
    • Run14 AuAu 200 GeV prod_low/mid - waiting for PWG QA to resume
  • Data restoration
    • Run16 st_upc MuDst - done
    • Run11 AuAu 200 GeV - done (DD+RCF)
    • Run18 FXT AuAu 3 GeV - duplicated on DD
  • Anyone using MuDst of pp500_production_2013 P14ia and P14ig data? We have 2% - 60% on DD depending no the data stream. 
Conclusions
- Run17 pp 510 GeV st_physics: need a couple more weeks to produce jet tree from MuDst. 
- pp500_production_2013: ColdQCD PWG will check if anyone is using MuDst files of this dataset

4) Data production priority (PRIORITY LIST)
  • Run21: O+O vs. d+Au
  • Run22: st_physics, st_mtd, st_fwd, st_W
 Conclusions
- FCV PWG prefers to have a slightly higher priority for O+O than for d+Au. Looking forward towards QM 2023, if we want to show results from O+O, we probably need to produce them immediately after 11.5 GeV Au+Au data. Will continue to discuss this. 
- Run22 datasets will be produced after Run21 datasets. For the four main streams in Run22, st_mtd can be placed with lowest priority. ColdQCD PWG will discuss the relative priorities of the other three data streams.

NOTES

2) Organizational news for LFSUPC co-convener
  • Incoming: Yue Hang Leung
  • Outgoing: Dan Cebra
3) New PWGC meeting time: 9am BNL time on Fridays?

Conclusions: will change the meeting start time from next week (Nov. 18th)

4) Data production priority (PRIORITY LIST)
  • Run21: O+O vs. d+Au
    • Production time: 2 weeks each
    • Calibration time: d+Au - 4 weeks; O+O - a few months
  • Run22: st_physics, st_mtd, st_fwd, st_W, st_upc, st_zerobias
Conclusions: 
- One suggestion: (Run20+21) 26.5 FXT (7.2) > 3.85 FXT I (3.0) > 44.5 FXT (9.2) > 70 FXT (11.5) > 100 FXT (13.7) > 200 GeV d+Au  > 200 GeV O+O >? 17.3 COL  > 3.85 FXT II (3.0). Will continue the discussion next week.
- PWGs are asked to poll the interests of analyzing O+O data for QM
- Suggested Run 22 priority: st_upc > st_zerobias > st_W > st_physics > st_fwd > st_mtd
-- ColdQCD PWG will determine a list of runs for EMC calibration, which could be produced before physics production
-- it should be very fast to produce st_upc and st_zerobias streams
-- need to discuss with S&C team whether it is efficient to produce st_zerobias stream standalone and couple it with other data streams
 
5) Embedding production
  • Mismatch seen in nHits distributions was identified to be offline vs. online cluster finder, which is now fixed for Run18 and BES-II. (See DETAILS here)
  • Need 1-2 weeks to fine tune TpcRS after fixing the cluster finder issue
  • Do we need to prioritize the embedding requests or just follow the natural order according to the request date (first come first serve)?
  • FXT embedding strategy
Conclusions: 
- Currently, we can go with the natural order of embedding requests, i.e. first come, first serve
- Will discuss priority for embedding production needed for HP2023 conference
- Dan presented and submitted some FXT embedding request with high priority in order to verify if it is OK to combine embedding production for various FXT energies


6) Agenda for Dec. analysis meeting: DRAFT

Conclusions: will continue the discussion next week

Conclusions: sizable UrQMD simulations have been produced for several energies, which can be found here: /gpfs01/star/pwg_tasks/simulations/UrQMD. PWGs will continue the discussion on this topic, and feedback from analyzers are very welcome. 

2) Forward triggers for Run23 Au+Au run
  • Expected to present trigger configurations, thresholds, rates, etc, at the forward meeting in Aug/Sep
Conclusions: conveners will ask proponents of mid+forward rapidity Jpsi trigger in UPC  to present their studies in a LFSUPC weekly meeting

3) Collaboration meeting
  • Take presenters' time zone into account when scheduling talks in the parallel sessions
  • Food truck operates between 11am - 1 pm at BNL. 
Conclusions: 
- Anyone who wants to attend the meeting in person should fill out the form (https://forms.gle/H5gAn22nGQNF7U78A) such that organizers know the head-count. There is a limit of 50 people for the BNL large seminar room. 
- If none of the conveners plans to attend the meeting in person, it is recommended to find a delegate who will be in charge of the parallel session on site

4) Disassemble GPC #216 and #276

Conclusions:  Dan will confirm with all PAs of the two GPCs about the disassembly.

1) Paper preview: Measurements of unpolarized cross section and transverse single spin asymmetry of $Z^{0}$ in 500/510 GeV p+p collisions
- Brief introduction from the PWG conveners (5’) [Qinghua Xu]
- Paper proposal (15')  [Presentation by Xiaoxuan Chu]
- Open discussions (35')
- Summary from the conveners' panel (5’)
 
Proposal page: https://drupal.star.bnl.gov/STAR/blog/xchu/Z0-cross-section-and-TSSA-paper-proposal
PA: Elke-Caroline Aschenauer, Xiaoxuan Chu, Oleg Eyser, Salvatore Fazio
Target journal: PLB

NOTES
 
2) Zoom meeting on Aug.  22nd to discuss input from STAR on the Longe Range Plan (LRP)
  • Each PWG prepares 2-3 slides on what you think is/are the most important discovery(ies)/interpretation(s) from STAR since the last LRP
Conclusions
- Zoom link: https://bnl.zoomgov.com/j/1602246597?pwd=aTFqdnp0dHlQS05meGt4VFhEeWRtUT09
- Agenda: https://drupal.star.bnl.gov/STAR/event/2022/08/22/LRP-planning-STARRHIC
- Everyone is welcome to join
- These important results could be ideas from before last LRP, but we have gained important insights into them since last LRP
- These presentations from each PWG hopefully will serve as the starting point for the white paper

3) Run21 7.7 GeV COL data
  • Production done
  • An issue in nSigmaX distribution is found. See details here. This is being investigated. 
Conclusions: there seem potential issues with eTOF as well. Will inform the experts. A reproduction of MuDst or PicoDst is likely needed. 

4) Run19 14.6 GeV bad run and centrality almost ready
5) Cold QCD: request to reproduce Run17 st_fms data by adding "pp2pp" option. Only MuDst's are needed. (SLIDES)
  • Current production: P18ic, "DbV20171001 pp2017a StiCA btof mtd mtdCalib PicoVtxDefault fmsDat fmsPoint fpsDat BEmcChkStat OSpaceZ2 OGridLeak3D"
  • Which library is preferred, previous one or the latest one?
Conclusions:
- Will consult with PAs which library is preferred
- Since there are no large ongoing production, the proposal is to start this production immediately and share the farm with other BES-II production when they are ready 

6) Tasks for Code QA
  • Reproduce exactly the analysis results,  provided by PAs, based on a few (1-2) MuDst/PicoDst/Embedding files
  • Reproduce paper figures based on the instructions, codes, histograms from full statistics, all provided by PAs
Conclusions: 
- Conveners are generally supportive of this proposal. Will apply them to new GPCs.
- For currently active GPCs, Rongrong will remind them that all the analysis codes, not just the plotting macros, should be committed to CVS. 

7) Embedding helper: FCV PWG

Conclusions: 
- We have found two embedding deputies: Maowu Nie (SDU), Xionghong He (Lanzhou)
- The FCV PWG will continue to search for a helper. But Xianglei can already start with the current team (2 deputies, 5 helpers)

8) Submitted presentations (LINK)

Conclusions: conveners and PAC will go through the list of submitted presentations to provide comments or discard obsolete entries. 

9) Deadline information, when available, is now included in the notification email

NOTES
  
2) Centrality meeting on Oct. 18th, 11am BNL time AOB
- What is the definition of small-sized dataset that could be duplicated on DD?
- At this point, we suggest that PWGs ignore this criteria and list all the datasets that they want to be duplicated on DD. Once we receive feedback from all PWGs and decide on a priority list, we will discuss with the S&C team to see which datasets can be actually duplicated due to the capacity of the DD.

- What is the current progress of BES-II embedding?
- A postdoc from BNL/KSU is leading the efforts to understand the issue and tune TpcRS. Currently, the discrepancy between data and embedding seems to originate from different TPC cluster finders used. Further investigations are ongoing.
