Neutrino masses, leptogenesis and dark matter in hybrid seesaw
Pei-Hong Gu, M. Hirsch, Utpal Sarkar +1
We suggest a hybrid seesaw model where relatively ``light''right-handed neutrinos give no contribution to the neutrino mass matrix due to a special symmetry. This allows their Yuka…

Radiative seesaw in left-right symmetric model
Pei-Hong Gu, Utpal Sarkar
There are some radiative origins for the neutrino masses in the conventional left-right symmetric models with the usual bi-doublet and triplet Higgs scalars. These radiative contri…

Extended Zee model for Neutrino Mass, Leptogenesis and Sterile Neutrino like Dark Matter
Narendra Sahu, Utpal Sarkar
We propose an extension of the standard model with a global symmetry that accommodates radiative neutrino masses along with dark matter and leptogenesis. The obser…
