Description

Electrons from W^± decays have been observed in longitudinally polarized p+p collisions at sqrt{s} = 500 GeV in the PHENIX detector at RHIC. The electron energy spectrum from W decays measured with an integrated luminosity of approximately 10 pb^-1 will be shown. A measurement of the electron single spin asymmetry which measures the spin structure of flavor identified quarks and antiquarks in the proton will be reported.
