Abstract

The PHENIX Experiment on the Relativistic Heavy Ion Collider (RHIC) with its use of beams of polarized protons, provides a unique environment of hard scattering between gluons and quarks complementary to that provided by deep inelastic scattering (DIS). Polarized proton proton collisions can directly probe the polarized gluon and anti-quark distributions as the collisions couple the color charges of the participants. We will give a brief overview of the PHENIX Spin Program and we will report recent results of the many probes accessible to the PHENIX experiment.
