Measurement of Longitudinal Spin Asymmetries for Weak Boson Production in Polarized Proton-Proton Collisions at RHIC
We report measurements of single- and double-spin asymmetries for W± and Z/γ∗ boson production in longitudinally polarized p+p collisions at √s=510 GeV by the STAR experiment at RHIC. The asymmetries for W± were measured as a function of the decay lepton pseudorapidity, which provides a theoretically clean probe of the …
