W Boson Production in Polarized p+p Collisions at RHIC
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, AL, from the STAR Collaboration's 2009 data at s=500 GeV.
