Abstract

High-Q^2 NC and CC DIS cross sections have been measured by H1 and ZEUS at HERA. Both NC and CC results based on data taken during the year 1994-2000 are in good agreement with Standard Model expectations. The structure function xF_3 is extracted from the NC cross sections and the mass of the W propagator is extracted from the CC cross sections. Valence quark distributions are derived by means of an NLO QCD fit.
