Indirect measurement of sin2θW (or MW) using μ+μ- pairs from γ* /Z bosons produced in p p ̄ collisions at a center-of-momentum energy of 1.96 TeV INDIRECT MEASUREMENT of sin2θW (OR ... T. AALTONEN et al.

Abstract:

Drell-Yan lepton pairs are produced in the process pp̄→μ+μ- +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 μ+μ- pair is used to obtain the effective leptonic determination sin2θefflept of the electroweak-mixing parameter sin2θW, from which the value of sin2θW is derived assuming the standard model. The measurement sample, recorded by the Collider Detector at Fermilab (CDF), corresponds t...
