Description
The PHENIX collaboration has been developing detector upgrade plans for enhanced physics programs using full luminosity of recent upgraded RHIC facility. This upgrade, referred to as sPHENIX, provides a variety of programs with heavy-ion collisions and polarized proton collisions at RHIC. We're proposing a major upgrade of the central-rapidity spectrometer consisting of a solenoidal magnet surrounded by electromagnetic and hadronic calorimeters with uniform coverage over |eta| < 1. The upgrade enables a crucial jet physics program to investigate the nature of the strongly-coupled quark-gluon plasma. Additional tracking layers and a preshower will expand the sPHENIX program to include heavy-flavor, neutral pion, low-mass dilepton, and direct photon measurements. Moreover we have been developing a forward-rapidity spectrometer upgrade plan with the open geometry. It has been designed for the study of cold nuclear matter effects in proton- and deuteron-nucleus collisions, precision measurements of single transverse-spin asymmetries for the Drell-Yan process, and measurements of novel observables in jet production in transversely polarized proton collisions.
