Stability and leptogenesis in left-right symmetric seesaw models

High Energy Physics - Phenomenology 2007-10-15 v1

Abstract

In left-right symmetric seesaw models an eight-fold degeneracy among the right-handed neutrino mass matrices is known to exist. We use stability and viability of leptogenesis as criteria in order to discriminate among the degenerate solutions and to partially lift the eight-fold degeneracy.
