Abstract

The production of W±W^\pm bosons in longitudinally polarized p+p collisions at RHIC provides a new means of studying the spin-flavour asymmetries of the proton sea quark spin distributions. Details of the W±^\pm event selection through the e±e^\pm decay channel at mid-rapidity are presented, along with preliminary results for the production cross section and parity-violating single-spin asymmetry, ALA_L, from the STAR Collaboration's 2009 data set at s=500\sqrt{s} = 500 GeV. Lastly, the expected sensitivities for future running are discussed.
