Abstract

The production of W^± bosons in longitudinally polarized p+p collisions at RHIC provides a new means of studying the spin-flavor asymmetries of the proton sea quark distributions. Details of the W^± event selection in the e^± decay channel at mid-rapidity are presented, along with preliminary results for the production cross section and parity-violating single-spin asymmetry, A_L, from the STAR Collaboration's 2009 data at √(s)=500 GeV.
