    BNL review of RHIC detector upgrades, March 14th 2006


Goals of PHENIX upgrades program

PHENIX upgrades at a glance
detector systems and status

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
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)                                requires highest
      Jet tomography (high pT PID, jet-jet and g-jet)                   AA luminosity
      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
