Towards a realistic MSSM prediction for neutrino-nucleon deep-inelastic scattering

摘要

We discuss the radiative corrections to charged and neutral current dcep-inelastic neutrino-nucleon scattering in the minimal supersymmetric standard model (MSSM). In particular, we study deviations, delta R-v((v) over bar), from the Standard Model prediction for the ratios of neutral- to charged-current cross sections, taking into account all sources for deviations in the MSSM, i.e. different contributions from virtual Higgs bosons and virtual superpartners. Our calculation includes the full q(2) dependence of the one-loop amplitudes, parton distribution functions and a NuTeV-inspired process kinematics. We present results of a scan of delta R-v((v) over bar) over the relevant MSSM parameter space.
