Hello Shinichi,

Thank you for your email, I have added the plots you asked for. You were indeed correct about my FXT kinematic acceptances, I compounded it with the Collider kinematic acceptances.

I have separated them now and added the 2D histograms.

Dear Rutik

I looked at the top-right panel in your slide 3. Why is your entry is smaller by factor of 2 

compared to the top-left? It looks like you start with the UrQMD sample with |eta_cm|<0.5 

(pre-selection) cut and give additional cut with FXT eta window, or? I would think you need 

to start without any pre-selection cut on UrQMD sample and to apply FXT kinematic cut 

just after the boost. I think the upper edge of the eta distribution in the FXT frame without 

any kinematic cut should start from (close to) zero in eta towards negative… 

Looking at the lower-left panel, it looks we might have quite significant spectator contribution 

with |eta_cm|<0.5 cut, I would like to suggest you to look at 2D eta-pT distribution in both 

frames without any kinematic cut, first. Please also try to look at the resulting c_m with 

|eta_cm|<0.2 in order to be dominated by the participant region, alone… 

Thank you very much. 

Best regards, ShinIchi

Hello Conveners, 

I’d like to give an update on pt-pt correlations at 3GeV. I shall upload my slides ASAP.

Dear CF Activists,

We invite you to our weekly CF PWG meeting on Thursday, December 21st, at 9:00 AM (BNL time).

If you would like to contribute, please let me know the latest 6 hours before the scheduled meeting.

Taking into account the average duration of the meeting and the number of contributions, we decided to limit the duration of a single meeting to 90 minutes. This will help us to focus on the discussed content. 

Please post your slides at least 6 hours before the presentation to allow everybody to look at the slides before the meeting. 

We will connect via Zoom. Please find the connection details under the meeting webpage.

Thank you,

Hanna and Nu
