sPHENIX cold QCD topical group

["Bazilevsky, Alexander" <shura AT bnl.gov>]

    Dear ColdQCD-ers, 
    
    We plan to submit two abstracts for the coming DIS-2020 to be held
    in Brooklyn Mar 23-27, with abstract submission deadline Jan 31. We
    consider to submit them without speaker names, which will be
    discussed and assigned after talks are accepted. All
    corrections/suggestions are welcome. 
    
    Thanks, 
    Sasha. 
    
    1.
      Cold QCD physics
      program with sPHENIX and potential
    forward
    upgrades
    
    The
          sPHENIX detector at BNL’s
        Relativistic
          Heavy Ion Collider (RHIC)
          will enable a spectrum of new or improved cold
          QCD measurements.
        With
                its excellent tracking and full calorimetry (hadronic
                and electromagnetic) in the central pseudo-rapidity
                region, sPHENIX provides excellent opportunities for the
                studies of the partonic structure and dynamics in
                nucleons and nuclei. This
                      includes the studies of the polarized structure of
                      the proton utilizing RHIC's polarized proton
                      collisions. Measurements
                            will also take advantage of RHIC's unique
                            capability to collide polarized protons
                            on nuclei, which provides
                            novel opportunities to study nuclear effects
                            with spin observables. A
                                  potential upgrade to sPHENIX with
                                  forward instrumentation could
                                  significantly enhance these physics
                                  capabilities, expanding
                                          the probed kinematic range to
                                          lower and higher parton
                                          momentum fraction x.
                                  The cold QCD nuclear physics program
                                  for the proposed sPHENIX midrapidity
                                  detector as well as the enhanced
                                  program enabled with forward upgrades
                                  will be presented.

2. sPHENIX detector development for potential forward upgrades

The sPHENIX detector at BNL’s Relativistic Heavy Ion Collider (RHIC) will enable an array of new or improved cold QCD measurements, enhancing our understanding of fundamental QCD. A potential upgrade to sPHENIX with forward instrumentation could significantly enhance the physics capabilities of the sPHENIX barrel. In this talk we will detail plans for the addition of forward instrumentation to the sPHENIX detector and describe how sPHENIX is building on EIC R&D efforts to characterize the performance of forward calorimetry, tracking and particle identification for a variety of physics measurements.  Special emphasis will be given to the measured performance in recent test beams.
