STAR Flow, Chirality and Vorticity PWG

[Takahito Todoroki <todoroki AT bnl.gov>]

Dear Subash,

Shengli is right. We Tsukuba group is interested in this dataset to look at vn using 

the two-particle correlation and event-plane method to understand the kinematic dependence 

of vn i.e. the difference between STAR and PHENIX results.

A PhD student and/or myself will work on this analysis depending on the situation.

Best regards,

Takahito

Dear Subhash,

     A couple of groups are interested in the dAu and OO data set for QM preliminary. We listed the some of hot topics here:

1) One top priority is to gain insight on longitudinal dynamics to resolve differences from phenix. We do this by performing analysis within phenix acceptance and both dAu and OO are useful:

v2{2}, v3{2} and v2{4} vs Nch and Pt in dAu and OO && 2p vs EPD method----Chuan Sun, Shengli Huang, Jiangyong Jia(SBU) 

And I believe that Tsukuba group will also interested in this topic

2)The other top priority is to probe the internal nuclei structure such as alpha cluster in Oxygen and vn-pt correlation will be powerful tool to study it:

Measurement of vn-pt correlation in dAu and OO: Shengli, ChunJian Zhang, Jiangyong Jia(SBU)

3)The lambda polarization in small system is also a very hot topic and SDU are interested for it:

Lambda polarization: Xingrui Gou, Zhenyu Chen, Qinghua Xu(SDU)

4)Decorrelation in dAu and OO: Gaoguo Yan, Zhenyu Chen(SDU)

5)Flow in v-proton collisions from dAu:Prithwish(BNL)

Those are hot topics which we would like to push for the QM preliminary. Therefore adjustment of production priority for dAu and OO will be much helpful!

Thanks!

Dear All,

You may have seen email from Rongrong (see below) that we are collecting
inputs for data production priorities keeping QM'23 in mind. Please let
us know if you or your group are involved/interested in analysis for O+O
or d+Au systems targeting for QM? It will help us setting up priority of
production for these datasets.

Thanks and regards,
Subhash
for FCV conveners

ps:Here is Rongrong's email:

4) Data production priority (PRIORITY LIST)
https://drupal.star.bnl.gov/STAR/pwg/common/production-priorties
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
