sPHENIX cold QCD topical group

["Mattson, Gregory William" <mattson5 AT illinois.edu>]

Hi all,

Please see the updated abstract draft:

The sPHENIX experiment is a new detector at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory. Designed for precision measurements of jet and heavy-flavor observables, sPHENIX provides precision vertexing, tracking, and electromagnetic and hadronic calorimetry in the central pseudorapidity region |eta| < 1.1 with full azimuthal coverage. In addition to measurements of the quark-gluon plasma produced in heavy ion collisions, sPHENIX also enables new and improved measurements in cold QCD. This talk will describe the status of an analysis of transverse single-spin asymmetries in pi0 and eta meson production using transversely polarized p+p collision data taken by sPHENIX in 2024. These asymmetries are sensitive to twist-3 multi-parton correlators, which are linked to the Sivers TMD PDF.

Best,

Greg

Hi Greg,

Indeed, I would suggest just deleting the last sentence in your abstract. And apply the other change that Dennis suggested. 

Best,

Caroline

Hi Dennis, Ralf, all,

Thank you for the feedback! You raise a very good point I had not considered.

I am not sure how to modify the last sentence, "Comparisons to existing results from the PHENIX experiment and to theoretical models will be shown." Would you recommend omitting this entirely?

Thanks,
Greg

Hi Greg,

I second Dennis' comment, we never promise results that are not yet

available even if it is likely by the time of the meeting/conference.

Please adjust the abstract accordingly.

Cheers,

Ralf

Hi Greg,

Thanks for the draft.

I guess since this is the APS March/April “Global” meeting, the

abstract is likely to just be accepted and we do not need too much

careful tweaking.

If I could make one suggestion, it would be to write “analysis” ->

“analysis status”. It seems plausible that sPHENIX could converge

on a Preliminary pi0/eta A_N on that March timescale, but since we

have not even officially formed PPGs yet (a topic for discussion in

the PCM tomorrow), it might be prudent to describe it as the status

report.

I hope you can also pick a snappy title!

Hello everyone,

I would like to propose an abstract for a talk at the APS meeting in

March 2025, focusing on the pi0 and eta A_N measurement. The

abstract submission deadline is next Friday, Oct 25. Please let me

know if you have any feedback or suggestions.

Thanks,

Greg
