Heavy Neutrino Threshold Effects in Low Energy Phenomenology

Abstract

Right handed neutrinos with mass of O (10 − 10) GeV are required to implement the see-saw mechanism and generate neutrino masses capable of playing a role in structure formation. Moreover models of fermion masses often relate the Yukawa couplings involving these neutrinos to the up-quark Yukawa couplings. Here we study the effects of such couplings on the… (More)
