Analytic reduction of transition amplitudes in radiative electroweak processes
arXiv:hep-ph/9804278
Abstract
It is shown that the transition amplitudes of radiative electroweak processes like $e^-e^+ \to ν_e \olν_e \ga$, $\ga e^- \to ν_e \olν_e e^-$, and $ν_e e^- \to ν_e e^- \ga$ can be reduced and factorized into simpler forms in the Standard Model. This method can be used in reducing many calculations of complicated radiative electroweak processes in general.
