Leptogenesis from R parity nonconservation
Thomas Hambye, Ernest Ma, Utpal Sarkar
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…
Lepton flavor mixing and baryogenesis
Kyunsik Kang, Sin Kyu Kang, Utpal Sarkar
Recently a new general class of quark mass matrix ansatz has been proposed, which originates from some flavor symmetry. We extend that symmetry to the lepton sector and study the n…
Models of Neutrino Masses and Baryogenesis
Utpal Sarkar
Majorana masses of the neutrino implies lepton number violation and is intimately related to the lepton asymmetry of the universe, which gets related to the baryon asymmetry of the…
CP violation in neutrino mixing matrix and leptogenesis
Yong Liu, Utpal Sarkar
The CP violation required in leptogenesis may have different origin, but in an effective theory they all are related to the rephasing invariant CP violating measure in the mixing m…
Neutrino Masses in Supersymmetry: R-Parity and Leptogenesis
Ernest Ma, Martti Raidal, Utpal Sarkar
In the supersymmetric standard model of particle interactions, R-parity nonconservation is often invoked to obtain nonzero neutrino masses. We point out here that such interactions…
