Description
The Parity violation of the weak interaction allows to use real W production in polarized proton-proton collisions as a tool to select
both helicity and flavor of the participating quarks and antiquarks.
With W+ production one is mostly sensitive to u and dbar quarks while W- production selects d and ubar quarks. The PHENIX experiment at RHIC has been taking data over the past several years at center of mass energies of around 500 GeV to measure W single spin asymmetries in the inclusive decays into muons at forward rapidities. The latest results will be presented.
