Deep-Inelastic e^+p Scattering at Very High Q^2 from ZEUS at HERA

Abstract

Neutral-current and charged-current deep-inelastic scattering at very high four-momentum transfer squared (Q^2) have been studied in positron-proton collisions at center-of-mass energy 300 GeV using the ZEUS detector at HERA. An integrated luminosity of 47.7 $p{b}^{-1}$ was collected in the years 1994-1997. Differential cross sections are presented for $Q^2>400Ge{V}^2$ and compared to Standard Model predictions.
