Description
Near the transition temperature, $T_C$, the strongly coupled QGP
exhibits nearly inviscid flow. How the quantum-bounded low viscosity
of QGP arises from the interactions of pointlike partons is not known
in detail. Addressing this fundamental question experimentally
requires measurements provided by scale-sensitive probes over a range
of temperatures in the vicinity of $T_C$. Fully reconstructed jets,
photons, and heavy flavor provide insight into the dynamics that
underlie these properties of the QGP.
The PHENIX collaboration is pursuing a major upgrade, sPHENIX,
consisting of the BaBar superconducting solenoid, large acceptance
hadronic and electromagnetic calorimetry and tracking. Coupled with
fast data acquisition, sPHENIX will be able to make use of the full
enhanced luminosity and species flexibility available at RHIC. The
detector design also leverages modern developments in sensors and
electronics---such as SiPMs and fast waveform digitization---and a
novel calorimeter geometry to provide the needed capabilities in a
cost-effective way. The measurements made possible by sPHENIX will
complement those currently being made at the LHC, and will enable a
comprehensive and exciting program of QGP measurements near $T_C$ in
the region of strongest coupling.
