Axel Drees, Stony Brook UniversityBNL review of RHIC detector upgrades, March 14th 2006

Overview of PHENIX upgrades 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

Physics Beyond the Reach of PHENIX Physics Beyond the Reach of PHENIX

High T QCD (AA, pA, and pp): Electromagnetic radiation (e+epair continuum)Heavy flavor (c- and b-production)Jet tomography (high pT PID, jet-jet and -jet)

Quarkonium (J/, ’ , c and (1s),(2s),(3s))

Spin structure of the nucleon:Gluon spin structure G/G (heavy flavor and -jet correlations) Quark spin structure q/q (W-production)

Low x phenomena gluon saturation in nuclei (particle production at forward rapidity)

Provide key measurements so far inaccessible at RHIC in three broad areas:

requires highestAA luminosity

All measurements base on existing capabilities enhance by detector upgrades
