Query: Determination of electroweak parameters at HERA with the H1 experiment   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.
