sPHENIX cold QCD topical group

["Riedl, Caroline" <criedl AT illinois.edu>]

Dear Spinners,

As you may remember, the previous RHIC Spin Plan comprised the period 2017-2023 (https://arxiv.org/abs/1602.03922), and now DOE asked us for its renewal (for the next 5+ years). Elke was charged to lead the effort.

Another plan ("The RHIC Cold QCD Program") was generated a year ago during the course of LRP developments: https://arxiv.org/abs/2302.00605. We intend to use it as a basis for the new RHIC Spin Plan with the updates having happened since then, and detailed information on contributing groups, topics, time scale and requested resources (computing, etc.) to accomplish the tasks.

To get it going, the initial meeting with the Spin conveners from PHENIX, sPHENIX and STAR was held last week.

sPHENIX will provide a list of institutions involved in spin analysis and how long which analysis will take to be completed. This may not be easy to pin down for sPHENIX since we haven't taken any spin data yet. We should also estimate the timescales for calibrations and reconstruction (calorimeter clusters, tracks, jets). The time granularity should rather be in fiscal years, not months.

Everyone is welcome to come up with any other ideas/suggestions and/or willingness to contribute. If there are any changes to your group or analysis plans, please let us know

Cheers,

Ralf and Caroline
