Radiative corrections to neutral current deep inelastic lepton nucleon scattering at HERA energies

We calculate the complete electromagnetique and weak radiative corrections of O(α3) to neutral current deep inelastic lepoton proton scattering at HERA energies in the framework of the quark parton model. QCD scaling violations in the leading logarithmic approximation are also included. We give predictions for the unpolarized cross section and the polarization and charge asymmetries and discuss the theoretical uncertainties due to the dependence of the radiative corrections on electroweak parameters, quark masses and parton distribution functions.
