Baryogenesis from a Lepton Asymmetric Universe
Marion Flanz, Emmanuel A. Paschos, Utpal Sarkar
We demonstrate that violation in the Majorana mass matrices of the heavy neutrinos can generate a asymmetric universe. The subsequent decay of the Majorana particles gene…
Low Energy Leptogenesis in Left-Right Symmetric Models
Avijit Ganguly, Jitendra C. Parikh, Utpal Sarkar
We propose a new mechanism for baryogenesis. We study the effective potential of left-right extension of the standard model and show that there can be a first order phase transitio…
A Model for the Three Lepton Decay Mode of the Proton
Biswajoy Brahmachari, Patrick J. O'Donnell, Utpal Sarkar
An extension of the left--right symmetric model has been constructed which gives in a natural way the three lepton decay modes of the proton which have been suggested as an explana…
Potential Minimization in Left-Right Symmetric Models
Biswajoy Brahmachari, Manoj. K. Samal, Utpal Sarkar
We study the Higgs potentials in the Left-Right symmetric model for various choices of Higgs fields. We give emphasis to the cases when the Higgs field is included to…
