Measurement of the longitudinal spin asymmetries for weak boson production in proton-proton collisions at root s=510 GeV Academic Article uri icon

abstract

  • 2019 authors. Published by the American Physical Society. We report new STAR measurements of the single-spin asymmetries AL for W+ and W- bosons produced in polarized proton-proton collisions at 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 and d quark helicity distributions for 0.05
