Measurement of Neutral and Charged Current Cross-Sections in Electron-Proton Collisions at HighQ2 at HERA H1 Collaboration

The inclusive e p single and double differential cross sections for neutral and charged current processes are measured with the H1 detector at HERA. The cross sections are measured in the range of four-momentum transfer squared Q2 between 200 and 30 000 GeV2, and Bjorken x between 0:0032 and 0:65. The data were taken with the H1 detector at HERA in 1998 and 1999 with a centre-of-mass energy of 320 GeV, and correspond to an integrated luminosity of 15:3 pb 1. The data are compared to recent measurements of the inclusive neutral and charged current e+p cross sections. Clear evidence is observed for parity violating Z0 exchange. The data are found to be in good agreement with Standard Model predictions.
