sPHENIX discussion of physics

["Perepelitsa, Dennis" <dvp AT bnl.gov>]

Dear sPHENIX colleagues,

Thanks to the many collaborators who have prepared and commented on draft 
poster abstracts. As Gunther mentioned on this email list last week, we are 
now in editing these in a “central” manner, with more information on the 
exact procedure for submission to come soon.

In this email, we are circulating draft abstracts for parallel talks (see 
below). We propose to submit three abstracts, discussing the readiness of the 
experiment for jet, heavy flavor, and bulk physics, to parallel tracks 
appropriate for those topics. We have attempted to draft these in a way 
where, while we do not explicitly promise any particular physics result, we 
will have the flexibility to include whatever combination of technical, 
performance, or early physics results is appropriate at the time of the 
conference.

Since the QM’23 abstract submission deadline is Monday, 1 May, any feedback 
before the end of the weekend on the strategy or wording from the 
Collaboration would be welcome.

Dennis, for Anne, Dave, Gunther, and Marzia

Readiness of the sPHENIX experiment for jet physics
Track: Jets

sPHENIX is a new collider detector at RHIC designed for pioneering studies of 
the Quark-Gluon Plasma with high-pT jet and heavy flavor probes. The jet 
physics program particularly relies on the sPHENIX calorimeter system, which 
consists of large-acceptance, hermetic electromagnetic and hadronic sections 
designed for high-resolution measurements of photons, electrons, hadrons, and 
jets. sPHENIX will begin commissioning with Au+Au collisions at 200 GeV in 
Spring 2023, with a large expected luminosity for measurements of jet 
production, structure, and correlations from the first year of data-taking. 
This talk will first give a technical report of the sPHENIX sub-systems 
relevant for jet physics and then present the status of the first physics 
measurements.

Readiness of the sPHENIX experiment for heavy flavor physics
Track: Heavy Flavor

sPHENIX is a new collider detector at RHIC designed for pioneering studies of 
the Quark-Gluon Plasma with high-pT jet and heavy flavor probes. The heavy 
flavor and quarkonia physics programs particularly rely on the sPHENIX 
tracking system, which consists of large-acceptance precision vertex, fast 
silicon strip, and time-projection chamber detectors designed for 
high-resolution measurements of the spatial origin and momentum of charged 
particles. sPHENIX will begin commissioning with Au+Au collisions at 200 GeV 
in Spring 2023, with a large expected luminosity for measurements of heavy 
flavor quark based probes of the QGP from the first year of data-taking. This 
talk will first give a technical report of the sPHENIX sub-systems relevant 
for heavy flavor physics and then present the status of the first physics 
measurements.

Readiness of sPHENIX experiment for bulk physics
Track: Collective Dynamics

sPHENIX is a new collider detector at RHIC. Although designed for pioneering 
studies of the Quark-Gluon Plasma with jet and heavy flavor probes, sPHENIX 
boasts significant capabilities for measurements of bulk physics phenomena, 
such as soft particle production and collective flow. For these measurements, 
sPHENIX features a large acceptance, excellent tracking efficiency, and a 
high data-taking rate, as well as a set of forward detectors for a detailed 
characterization of collision events. The experiment will begin commissioning 
with Au+Au collisions at 200 GeV in Spring 2023, with a large expected 
luminosity for its physics program in the first year of data-taking. This 
talk will first give a technical report of the sPHENIX sub-systems relevant 
for bulk physics and then present the status of the first physics 
measurements.
