momentum energy of 1 . 96 TeV

Drell-Yan lepton pairs are produced in the process pp̄ → μ+μ− + X through an intermediate γ∗/Z boson. The forward-backward asymmetry in the polar-angle distribution of the μ− as a function of the invariant mass of the μ+μ− pair is used to obtain the effective leptonic determination sin2 θ eff of the electroweak-mixing 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 pp̄ collisions at a center-of-momentum energy of 1.96 TeV, and is the full CDF Run II data set. The value of sin2 θ 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 the on-shell renormalization scheme, where sin2 θW = 1 − M2 W /M 2 Z , the measurement yields sin2 θW = 0.2233 +0.0009, or equivalently a W-boson mass of 80.365 +0.047 GeV/c2.ThevalueoftheW −bosonmassisinagreementwithpreviousdeterminationsinelectron− positroncollisionsandattheTevatroncollider.
