Study of Weak Charged Current in Polarized Lepton Deep Inelastic Scattering Including Higher Order Effects.
S. N. Sevbitov and T. V. Shishkina

The processes of lepton-nucleon scattering at ultra high energy provide important information about interaction and nucleon structure. Modern experiments give possibility to investigate lepton-nucleon deep inelastic processes with both polarized beams, allowing to analyze nucleon spin structure. As energy and experimental accuracy rise, necessity to improve Born cross sections and polarized asymmetries with higher order radiative corrections is appeared. In this paper Born cross sections as well as the lowest order radiative corrections to lepton-nucleon inelastic processes with charged weak current are considered. Higher-order effects are calculated analytically using Lorentz-invariant approach including both lepton and nucleon bremsstrahlung. Numerical analysis as well as discussion are presented.
Key words: deep inelastic scattering, charged current weak processes, nucleon spin structure, asymmetries, radiative corrections
