The Combined Measurements of NC and CC DIS Cross-Sections at HERA

摘要

A combination is presented of the inclusive cross sections measured by the H1 and ZEUS Collaborations in neutral and charged current deep-inelastic ep scattering at HERA. The combination uses data from unpolarized ep scattering taken during the HERA-I phase as well as measurements with longitudinally polarized electron or positron beams from the HERA-II running period. The combination method takes the correlations of systematic uncertainties into account. The inclusion of the large HERA-II data set leads to an improved uncertainty especially at large four momentum transfer squared Q~2.
