Drell-Yan lepton pairs are produced in the process pp¯ → μþμ− þ X through an intermediate γ=Zboson. The forward-backward asymmetry in the polar-angle distribution of the μ− as a function of the invariant mass of the μþμ− pair is used to obtain the effective leptonic determination sin2θlept eff of the electroweakmixing parameter sin2 θW, from which the value of sin2 θW is derived assuming the standard model. The measurement sample, recorded by the Collider Detector at Fermilab (CDF), corresponds to 9.2 fb−1 of integrated luminosity from pp¯ collisions at a center-of-momentum energy of 1.96 TeV, and is the full CDF Run II data set. The value of sin2 θlept eff is found to be 0.2315 0.0010, where statistical and systematic uncertainties are combined in quadrature. When interpreted within the context of the standard model using he on-shell renormalization scheme, where sin2θW ¼ 1 − M2 W=M2 Z, the measurement yields sin2 θW ¼ 0.2233 0.0009, or equivalently a W-boson mass of 80.365 0.047 GeV=c2. The value of the W-boson mass is in agreement with previous determinations in electron-positron collisions and at the Tevatron collider.
