The STAR W Program : New Results and Future Measurements
Abstract
The production of W 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 event selection through 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 set at s = 500 GeV. Lastly, the expected sensitivities for future running are discussed.
