Effects of the Scale-dependent Vacuum Expectation Values in the Renormalization Group Analysis of Neutrino Masses

Abstract

The contribution of scale-dependent vacuum expectation values (VEVs) of Higgs scalars, which gives significant effects in the evolution of fundamental fermion masses in the Minimal Supersymmetric Standard Model (MSSM), is now considered in the derivation of the one-loop analytic expression for the evolution of the left-handed Majorana neutrino masses with energies. The inclusion of such effect of the running VEV increases the stability of the neutrino masses under quantum corrections and leads to a mild decrease of neutrino masses with higher energies.
