Analytic reduction of transition amplitudes in radiative electroweak processes

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