Measurement of the Parity-Violating Longitudinal Single-Spin Asymmetry for W[superscript ±] Boson Production in Polarized Proton-Proton Collisions at [sqrt]s=500 GeV
We report the first measurement of the parity-violating single-spin asymmetries for midrapidity decay positrons and electrons from W+ and W- boson production in longitudinally polarized proton-proton collisions at [sqrt]s=500 GeV by the STAR experiment at RHIC. The measured asymmetries, AL[superscr...
