Abstract (english)
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 √s=500  GeV by the STAR experiment at RHIC. The measured asymmetries, AW+L=−0.27±0.10(stat.)±0.02(syst.)±0.03(norm.) and AW−L=0.14±0.19(stat.)±0.02(syst.)±0.01(norm.), are consistent with theory predictions, which are large and of opposite sign. These predictions are based on polarized quark and antiquark distribution functions constrained by polarized deep-inelastic scattering measurements.
