sPHENIX discussion of physics

["Huang, Jin" <jhuang AT bnl.gov>]

Dear Tracking and HF Team

Congratulations on the exciting progress shown in the preQM meeting today! We are writing to confirm the procedure for the HF preliminary performance plot approval as discussed in the meeting: 

• We request another update on D0 performance plot tomorrow (Thu). And either the Apr 2nd or 3rd tagged D0 result would be approved as preliminary 
• For the emerging Lc peak, we request constant analysis updates and open discussion on https://chat.sdcc.bnl.gov/sphenix/channels/joint-hfquarkonia-tg for the Lc analysis. If sufficient confidence is built for Lc peak, we could consider to approve it either in Thu 9AM EST preQM session or in the Sunday 1PM CEST rehearsal at Frankfurt (with zoom connection at https://indico.bnl.gov/event/26857/ ).
• The tracking IAN should be updated with new plot before presentations. 

This is an exceptional procedure given the importance of the first HF result and high stake conference. Looking forward to the exciting results. Happy peak hunting. 

Best regards,

Jin & Megan

Dear all,

Thank you for all the useful discussion at this morning's approval session and congrats to everyone working toward these impressive plots. The list of suggestions I noted during the meeting are listed below.

Best,

-Megan

Approval - Performance Plots April 2, 2025


Yuko - 2PC

Pile up numbers are calculated and documented in AN
-Rate ->MBD trigger rate
-explain in poster text that it’s a small fraction of events collected 
-20% needs to be unfolded to get contamination and have a smaller effect on the v2
-increase font size
-quote the range of rate
-dN/dclus / dN/dclus (>400Hz)
-pp -> p+p
-should have axis ticks on the top and right as well of 3D plots
-MVTX + INTT tracklets -> silicon tracklets  
-change pT label to pT > 1 GeV
-Trigger Mode to Trigger
-Can drop Y= part of 3D axis label


Joe - Tracking plots

-Slide 4-6:
-Add collision info and more detail on the left
-simplify axis labels to \Delta r \phi residual and define on the poster

-Increase font size of the collision info etc in plots on following slides
Slide 8:
-move MeV from next to sigma to after 8.9

Slide 10:
-Add width

Slide 11
-remove Kaon dEdx p cut label
-change Width to sigma
-table should include the dEdx cut

Slide 12
-Increase label sizes
-Add widths
-Make a version without the pull

Slide 13:
-move MeV from next to sigma/mu to after the number  
-update at tomorrow’s approval session and plan to approve there

Slide 14:
-Updates to the Lambda_c plot are ongoing and being updated via Mattermost discussion

-For approved plots, update the note and send the preliminary stamped figures to Dennis once everyone's comments are addressed

Dear Collaborators

We had a productive day-1 of preQM meeting! Today, we will start with QM25 plenary talk rehearsal by Christof Roland starting at 10AM EDT, which is followed by PPG04 and performance approval sessions. Zoom link and recording at https://indico.bnl.gov/event/26857/ 

Best regards

Jin & Megan

Dear Collaborators

Please join our preQM meeting week, starting soon at Monday 9AM EDT: https://indico.bnl.gov/event/26857/  . The Monday session starts with a brief collaboration status update, followed by parallel QM25 talk rehearsal and PPG09 approval. 

• This preQM meeting is a zoom-based event. Zoom link on indico page above.  
• For collaborators at BNL, Physics building room 2-219 is reserved for the preQM week. 
• sPHENIX 1008 Conference may be used by collaborators joining preQM while working on the run, though the room use will prioritize Run25 related activity. 

Looking forward to talking to you soon

Best regards

Jin & Megan

Dear Collaborators

As the run and QM activity ramp up, we are writing to remind you again of a few exciting events in the coming week.  

• PPG ConfNote commenting periods ending: 

• PPG-09 inclusive jets in p+p, comment deadline today, https://sphenix-invenio.sdcc.bnl.gov/records/00nre-xdn68 
• PPG-04 underlying event in Au+Au, comment deadline tomorrow, https://sphenix-invenio.sdcc.bnl.gov/records/dfgeh-d6p63 

Friday Mar 28, Noon @ 1008: start of run Taco party. 

Monday/Tue Mar 31/Apr 1st: potential for first collision and start of beam studies, followed by physics data taking 

Monday-Thu Mar 31-Apr 3: preQM meeting

• Indico: https://indico.bnl.gov/event/26857/ , starting Monday 9AM
• For BNL participants, primary room: Physics building 2-219, satellite room: BNL 1008 conference room (at lower priority than run-related events)

Sunday Apr 6: QM25 in person rehearsal at conference site (at student day venue). Details to come.

We will NOT have Physics Coordination Meeting, General Meeting and preGeneral Meeting this/next/QM week, given the Run start and QM meetings. Nonetheless, we will give news introduction with brief run report slides at the beginning of preQM meeting

We would like to thank our collaborators working hard preparing the impressive set of new results for QM25 and those dedicated for Run25! Hope to see you soon at one of the events.

Best regards

Jin & Megan for Management Team
