Abstract
The inclusive single and double differential cross-sections for neutral and charged charged processes with four-momentum transfer squared Q(2) between 150 and 30 000 GeV2 and with Bjorken x between 0.0032 and 0.65 are measure d in e(+)p collisions. The data were taken with the H1 detector at HERA bet ween 1994 and 1997. and they correspond to an integrated luminosity of 35.6 pb(-1). Tho Q(2) evolution of the parton densities of the proton is tested , yielding no significant deviation from the prediction of perturbative QCD . The proton structure function Fz(x, Q(2)) is determined. All extraction o f the u and d quark distributions at high x is presented. At high Q(2) elec troweak effects of the heavy bosons Z(o) and W are observed and found to be consistent with Standard Model expectation.
