STAR Correlations and Fluctuations PWG

[yghuang <yghuang AT mails.ccnu.edu.cn>]

Dear Conveners,

If time allows, I would like to give a remote talk on ‘updates on net-proton cumulants from BES-II collider energies’.

Detailed information is as follows:

1.1) Analysis topic: Net-proton cumulant study from 11.5 GeV to 19.6 GeV (with previous embedding)

1.2) Expected timeline: waiting for latest requested high statistic embedding data and finish the calculations (including systematic uncertainty) with them (for all COL data sets) by this May. The analysis note is parallel ongoing and will be ready as soon as we finish the analysis. Paper draft will be completed soon as well.

1.3) Requests: no more requests as high statistic embedding requests have already been submitted.

2.1) Paper status: We are still in the analysis stage.

2.2) Physics points: 

2.2.1) For short paper: Complete energy dependence of cumulant ratios (e.g. C4/C2). With upgrades of detector, we have wider acceptance and better centrality resolution, as well as more statistics (i.e. smaller uncertainties). Those updated hardware and experimental conditions may give us a brighter sight to reveal the physics that colliders / detectors are showing us.

2.2.2) For long paper: More detailed discussions will be presented here, including centrality dependence, rapidity scan and pT scan of proton/antiproton/net-proton cumulants and factorial cumulants for each collider energy. 

2.3) Timeline: Detailed time schedule has not been determined yet.

3.1) I would attend the meeting online.

3.2) My preferred title is: updates on net-proton cumulants from BES-II collider energies.

If more information is needed, please let me know.

Best regards,

Yige

Hi All,

Since we have not received any discussion items for today’s meeting, I suggest one topic:

CF-PWG discussion during next STAR Collaboration meeting March 18-22 at BNL:  

Please let us know of the following:

(i) Your analysis topic, timeline, request(s) such as embedding …;

(ii) Your paper status, physics point(s), timeline, …;
(iii) If you plan to attend the meeting in-person or zoom, presentation title

We will start to collect these info and preparing for the PWG report at the collaboration meeting.

Many thanks,

Hanna and Nu
