 So far we have received response from 


------------------------------------------------------------------------------
1. Shengli, 
1) v2,v3 as a function of pt in different centrality from tpc-tpc and tpc-epd methods
2)integral v2(2), v2(3)and v2(4) vs centrality
3)vn-pt vs centrality

------------------------------------------------------------------------------
2. Zuowen, 
1）List of promised results
    a) v1/v2 of pi+/pi-, K0s and lambda at 3, 3.2, 3.5, 3.9 GeV (anti-flow of kaons)
    b) v2 of pi/K/p, phi, K0s, lambda, cascade and omega at 7.7, 14.6, 19.6 GeV (NCQ scaling of v2)
    c) v1 of pi/K/p, phi, K0s, lambda at 7.7, 14.6, 19.6 GeV (energy dependence of net-particles v1)
2) Status of analysis
a) We have show systematic uncertainty study for  v1/v2 at 3, 3.2, 3.5 GeV and requested preliminary. And we would also show systematic study at 3.9 GeV at next week on FCV meeting.
b) v2 at 14.6 and 19.6 GeV results are already STAR preliminary. For 7.7 GeV, centrality definition is not finalized, we plan not show v1/v2 at 7.7 GeV in our talk.
c) v1 at 19.6 GeV results are already STAR preliminary. 
d) v3 at 19.6 GeV results are already STAR preliminary.
3) Potential issues
 a) centrality definition at 7.7 GeV

3. Zhiwan, 
-- list of promised results observables, collision system, beam energies,
   CME: Delta gamma of h-h, including intercept, 7.7 GeV AuAu , 11.5 GeV AuAu , 14.6 GeV AuAu, 19.6 GeV AuAu, 27 GeV AuAu (BES-II)
        Delta gamma, value of intercept, 200GeV Au+Au
   CVE: Delta gamma of lambda-p, including intercept, 19.6 GeV AuAu, 27 GeV AuAu (BES-II)

-- status/readiness of your analysis
   CME: 14.6, 27, 200 GeV AuAu, central values finished, systematics finished.
        7.7, 19.6 GeV AuAu central values finished, systematics ongoing.
        11.5 GeV need more time to started
   CVE: 19.6, 27 GeV AuAu, central values finished, systematics ongoing.
-- any potential issues, show stoppers, centrality/embedding
      - 11.5 GeV has no official centrality so far. I am running my own QA and will use old centrality. If time does not allow, we could possibly skip this data set.

4. Xingrui,
 -- list of promised results observables, collision system, beam
energies
   Re: Global and local polarization of Lambda/AntiLambda hyperons in
isobar collisions at 200GeV.

   -- status/readiness of your analysis
   Re: At present, both my results and Hu Qiang’s results for QM2023 have
been preliminary approved, but there is no news about Kokubo’s
results(correlation between the global polarization and directed flow).
I have sent him an email to remind him to preliminary, but have not
received a reply.

   -- any potential issues, show stoppers, centrality/embedding  etc.
   Re: If time permits, I would like to talk about the "Update on Pyc2 in
isobar collisions" at the upcoming FCV meetings on August 9th and 16th.

6. Rishabh,

Here is a summary of the key points:
– Our initial plan was to show v2 and v3 of light nuclei in Au+Au collisions at √sNN = 7.7 - 54.4 GeV.
– In the upcoming FCV meeting, I will discuss the v3 results of light nuclei (protons and deuterons) in Au+Au collisions at √sNN = 14.6, 19.6, 27, and 54.4 GeV. I already have preliminary v2 results.
– Depending on the availability of the bad run list and centrality, I may include 7.7, 9.2, and 11.5 GeV results.

7. Chengdong,

1. list of promised results observables, collision system, beam energies
List of promised results observables: 1) Light-Nuclei Directed Flow v1 ; 2) Hyper-Nuclei Directed Flow v1 ; 3)  Light-Nuclei Elliptic Flow v2 Measurements;
Collision system: Au+Au Collisions at RHIC-STAR
Beam energies: 2019 3.2 GeV (4.59 A GeV);  2020 3.5 GeV (5.75 A GeV); 2020 3.9 GeV (7.3 A GeV)

2. Status/readiness of your analysis
1) Currently, there are already 3.2 GeV embedding data, we have made efficiency corrections to the 3.2 GeV Light-Nuclei v1(v2) and Hyper-Nuclei v1, so we have preliminary Light-Nuclei v1(v2) and Hyper-Nuclei v1 analysis results of 3.2 GeV.
2) At present, there is no embedding data for 3.5 GeV and 3.9 GeV, so we are currently using the embedding data of 3.2 GeV to take efficiency corrections for 3.5 GeV and 3.9 GeV of Light-Nuclei and Hyper-Nuclei Collectivity.

3. Any potential issues, show stoppers, centrality/embedding  etc.
1）Only the 3.2 GeV data [2019 3.2 GeV (4.59 A GeV)] has an official centrality definition; and 3.5 GeV[2020 3.5 GeV (5.75 A GeV)] and 3.9 GeV[2020 3.9 GeV (7.3 A GeV)] have no official definition yet.
2) Currently, there is no embedding data for 3.5 GeV and 3.9 GeV, so we are currently using the embedding data of 3.2 GeV to take efficiency corrections for 3.5 GeV and 3.9 GeV of Light-Nuclei and Hyper-Nuclei Collectivity. This may cause some fluctuation to the final results of the 3.5 GeV and 3.9 GeV of Light-Nuclei and Hyper-Nuclei Collectivity.

8. Xiaoyu,

-- list of promised results observables, collision system, beam energies 

  • Charged particle v1 at large |\eta| for Au+Au at 27 GeV and 19.6 GeV
  • Proton v3 using the first-order event plane vs centrality, rapidity, and pT for collision energies 3.2, 3.5, and 3.9 GeV fixed target.
  • Pion, deuteron and triton v3 using the first-order event plane for collision energies 3.2, 3.5, and 3.9 GeV fixed target.


-- status/readiness of your analysis

  • v1  is ready, 27 GeV results have already been approved as preliminary, 19.6 GeV results has requested preliminary at FCV
  • Proton v3 data points complete and systematic uncertainties complete. Will request preliminary August 9th.
  • Pion, deuteron and triton v3 data points complete and systematic uncertainties complete.


-- any potential issues, show stoppers, centrality/embedding  etc.

  • Waiting for proton embedding for 3.2, 3.5, and 3.9 GeV.

9. Aditya,

The status for abstract id #347+356 is as follows

1) Promised results- Deltav1 as a function of rapidity, centrality and pT, rn(eta), G2(eta,phi), flow angular correlations, SC(n,m){4} and SC(n,m){6} in BES II

2) Status- Deltav1-19.6GeV systematics in progress, 14.6 systematics done, 7.7 running with official pile up cut and badrun list, Longitudinal de-correlation of 19.6, 27 and 54.4 GeV done

3) Rcf was slow which delayed the progress, we should be able to present the plots in the upcoming FCV meeting on 16th August.
