ZEUS results on high Q^2 DIS cross sections and QCD fits

Abstract

Single and double differential cross sections ds/dQ^2, ds/dx, ds/dy and d^2s/dQ^2dx of the inclusive neutral current (NC) measurement from the 98/99 e^-p and the charged current (CC) measurement from the 99/00 e^+p data sets are presented. With the previously published e^+p NC ZEUS measurement xF_3 and xG_3, and with the e^-p CC ZEUS measurement F_2^CC are extracted. The results are compared to the prediction of the Standard Model using parton density functions of the ZEUS next-to-leading-order QCD analysis which is reviewed.
