摘要

Drell-Yan lepton pairs are produced in the process pp¯→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 sin2θlepteff. A new method to infer sin2θW, or equivalently, the W-boson mass M_W 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 pp¯ collisions at a center-of-momentum energy of 1.96 TeV. The value of sin2θlepteff is found to be 0.2328 +- 0.0010. Within a specified context of the standard model, this results in sin2θW = 0.2246 +- 0.0009 which corresponds to a W-boson mass of 80.297 +- 0.048 GeV/c^2, in agreement with previous determinations in electron-position collisions and at the Tevatron collider.
