Spin Physics with W-bosons at RHIC

The spin physics program at the Relativistic Heavy Ion Collider (RHTC) at Brookhaven National Laboratory presents a unique opportunity to study the proton spin structure using hard probes and collider kinematics. In the future, measurements will be made of polarized proton collisions at a center of mass energy of √(s) = 500GeV. At the projected high integrated luminosities of ∼ 800pb-1 ample W+--bosons are produced. Measurement of the ratio of decay daughter leptons in the central and forward rapidity regions for opposite helicities of one of the polarized beams allows the dissociation of the proton spin contributions from up and down quark and anti-quark spins. The capabilities with the current detector configurations and future upgrades are discussed
