RHIC Spin Physics
  We describe the foreseen spin physics of the polarized proton-proton collider at RHIC. The study of the spin structure of the nucleon at RHIC is unique and complementary to the traditional polarized DIS experiments. The sensitivities of the gluon polarization measurement via prompt photon production and anti-quark polarization measurement using W production with the PHENIX detector system are reviewed.
