Query: CP violating decays in leptogenesis scenarios   We compute the CP violation in the decays of heavy electroweak singlet
neutrinos, arising from both the one--loop vertex corrections and the wave
function mixing. We extend the computation to the supersymmetric version of the
model and discuss the implications for the generation of a lepton number
asymmetry by the out of equilibrium decay of the heavy (s)neutrinos in the
early Universe, to be reprocessed later in the observed baryon excess by
anomalous electroweak processes.
