Leptogenesis from R parity nonconservation - art. no. 015010

It is known that realistic neutrino masses for neutrino oscillations may be obtained from R parity nonconserving supersymmetry. It is also known that such interactions would erase any preexisting lepton or baryon asymmetry of the Universe because of the inevitable intervention of the electroweak sph alerons. We now show how a crucial subset of these R parity nonconserving t erms may in fact create its own successful leptogenesis.
