Query: Analytic reduction of transition amplitudes in radiative electroweak
  processes   It is shown that the transition amplitudes of radiative electroweak processes
like $e^-e^+ \to \nu_e \ol{\nu}_e \ga$, $\ga e^- \to \nu_e \ol{\nu}_e e^-$, and
$\nu_e e^- \to \nu_e e^- \ga$ 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.
