Drell-Yan lepton pairs are produced in the process p̄p→e +e-+X through an intermediate γ*/Z boson. The lepton angular distributions are used to provide information on the electroweak-mixing parameter sin2θw via its observable effective-leptonic sin2θw, or sinâ¡2θefflept. A new method to infer sin 2θw or, equivalently, the W-boson mass MW in the on-shell scheme, is developed and tested using a previous CDF Run II measurement of angular distributions from electron pairs in a sample corresponding to 2.1 fb-1 of integrated luminosity from p̄p collisions at a center-of-momentum energy of 1.96 TeV. The value of sinâ¡2θefflept is found to be 0.2328±0.0011. Within a specified context of the standard model, this results in sin 2θw=0.2246±0.0011, which corresponds to a W-boson mass of 80.297±0.055 GeV/c2, in agreement with previous determinations in electron-position collisions and at the Tevatron collider. © 2013 American Physical Society.
