N2 - In left-right symmetric grand unified theories both the smallness of the neutrino mass and a sizable cosmological baryon excess can be ascribed to a superheavy Majorana lepton. We show, taking SO(10) as the simplest model of this kind, that the largest neutrino mass is constrained to lie between 10-3 eV and 100 eV in order to give the observed magnitude of baryon excess.
