Title: Measurement of the longitudinal spin asymmetries for weak boson production in proton-proton collisions at s = 510 GeV

Abstract

We report new STAR measurements of the single-spin asymmetries A L for W + and W - bosons produced in polarized proton–proton collisions at $$\sqrt{s}$$ = 510 GeV as a function of the decay-positron and decay-electron pseudorapidity. The data were obtained in 2013 and correspond to an integrated luminosity of 250 pb -1. The results are combined with previous results obtained with 86 pb-1. A comparison with theoretical expectations based on polarized lepton-nucleon deep-inelastic scattering and prior polarized proton–proton data suggests a difference between the $$\bar{u}$$ and $$\bar{d}$$ quark helicity 3 distributions for 0.05 < x < 0.25. In addition, we report new results for the double-spin asymmetries A LL for W ±, as well as AL for Z/γ* production and subsequent decay into electron–positron pairs.

abstractNote = {We report new STAR measurements of the single-spin asymmetries AL for W+ and W- bosons produced in polarized proton–proton collisions at $\sqrt{s}$ = 510 GeV as a function of the decay-positron and decay-electron pseudorapidity. The data were obtained in 2013 and correspond to an integrated luminosity of 250 pb-1. The results are combined with previous results obtained with 86 pb-1. A comparison with theoretical expectations based on polarized lepton-nucleon deep-inelastic scattering and prior polarized proton–proton data suggests a difference between the $\bar{u}$ and $\bar{d}$ quark helicity 3 distributions for 0.05 < x < 0.25. In addition, we report new results for the double-spin asymmetries ALL for W±, as well as AL for Z/γ* production and subsequent decay into electron–positron pairs.},
