CP Violation in Heavy Neutrino Mediated $e^{-}{e}^{-}\to W^{-}{W}^{-}$

Abstract

We consider the reaction $e^{-}{e}^{-}\to W^{-}{W}^{-}$ mediated by possible heavy neutrino exchange at future LINAC energies of $\sqrt{s}>>2m_W$. This reaction is sensitive to CP phases of the neutrino mixing matrices, even at the level of Born amplitudes. Certain integrated cross-sections are shown to have the power to resolve the CP phases when the experimental configurations are varied. Asymmetries sensitive to CP violation (involving initial QED phases) for $e^{-}{e}^{-}$ and $e^{+}{e}^{+}$ reactions are constructed and their consequences considered.
