Radiative Corrections in the Presence of Majorana Neutrinos

Abstract

We have studied the radiative corrections from the fourth generation leptons in the context of the see-saw mechanism. We have estimated numerically the differential cross section for the process (${\mathrm{e}}^{+}{\mathrm{e}}^{-}\to {\mathrm{W}}^{+}{\mathrm{W}}^{-}$) at one-loop level, and found in the cross section the threshold behaviors for Majorana neutrino productions.
