Real Photon Bremsstrahlung Corrections to Charged Current Lepton Deep Inelastic Scattering Processes.
S. N. Sevbitov and T. V. Shishkina

The processes of lepton-nucleon scattering, including ones with both polarized beams, at high energy provide relevant information about interaction and nucleon structure, 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 becomes substantial. In this report we stress on lowest order bremsstrahlung corrections treatment using helicity amplitudes method as applied to actual nowadays charged current lepton-nucleon deep inelastic processes, which allows to simplify matrix element calculation procedure. Real photon emission contribution is calculated by means of Lorentz-invariant formalism. Kinematical peculiarities on bremsstrahlung correction are discussed.
Key words: deep inelastic scattering, charged current weak processes, nucleon spin structure, asymmetries, radiative corrections
