Overview of PHENIX upgrades Goals of PHENIX upgrades program PHENIX upgrades at a glance detector systems and status physics reach of combined system new detector systems not covered today The FVTX and NCC proposals Submitted BNL to seek construction funds starting FY08 PHENIX internal review in December 2005
requires highest AA luminosity Physics Beyond the Reach of PHENIX Provide key measurements so far inaccessible at RHIC in three broad areas: • High T QCD (AA, pA, and pp): • Electromagnetic radiation (e+e- pair continuum) • Heavy flavor (c- and b-production) • Jet tomography (high pT PID, jet-jet and g-jet) • Quarkonium(J/, ’ , c and (1s),(2s),(3s)) • Spin structure of the nucleon: • Gluon spin structure DG/G (heavy flavor and g-jet correlations) • Quark spin structure Dq/q (W-production) • Low x phenomena • gluon saturation in nuclei (particle production at forward rapidity) All measurements base on existing capabilities enhance by detector upgrades Axel Drees
PHENIX Detector Upgrades at a Glance • Central arms: • Electron and Photon measurements • Electromagnetic calorimeter • Precision momentum determination • Hadron identification • Muon arms: • Muon • Identification • Momentum determination • Dalitz/conversion rejection(HBD) • Precision vertex tracking (VTX) PID (k,p,p) to 10 GeV (Aerogel/TOF) • High rate trigger (m trigger) • Precision vertex tracking (FVTX) • Electron and photon measurements • Muon arm acceptance (NCC) • Very forward (MPC) Axel Drees
