Recent Electroweak Measurements from the H1 and ZEUS Experiments

Abstract

Neutral-current ({NC}) and charged-current ({CC}) deep inelastic scattering ({DIS}) reactions have been studied in $e^{+}p$ and $e^{-}p$ collisions using the {H1} and {ZEUS} detectors at {HERA I}. Following the upgrade of the {HERA} accelerator, the {HERA II} program recently started with the first data in $e^{+}p$ scattering with longitudinally polarised positrons. In this paper, a summary of the electroweak results from {HERA I} and the first measurement of the cross section for $e^{+}p$ CC {DIS} at a longitudinal polarisation value of 33% from the {ZEUS} collaboration are presented.

Talk presented at Moriond EW 2004, La Thuile, Italy, March 21-28, on behalf of the H1 and ZEUS collaborations
