Determination of electroweak parameters at HERA with the H1 experiment

Abstract

Using deep inelastic $e^{\pm }p$ charged and neutral current scattering cross sections previously published, a combined electroweak and QCD analysis is performed to determine electroweak parameters accounting for their correlation with parton distributions. The data used have been collected by the H1 experiment in 1994-2000 and correspond to an integrated luminosity of 117.2 pb${}^{-1}$. The $W$ boson mass is determined via the propagator and in the on-mass-shell scheme. A first measurement at HERA is made of the light quark weak couplings to the $Z^0$ boson.
