Radiative Left-Right Dirac Neutrino Mass
Ernest Ma, Utpal Sarkar
We consider the conventional left-right gauge extension of the standard model of quarks and leptons without a scalar bidoublet. We study systematically how one-loop radiative Dirac…
High-scale baryogenesis with testable neutron-antineutron oscillation and dark matter
Pei-Hong Gu, Utpal Sarkar
We propose a new scenario for predicting a one-loop neutron-antineutron oscillation at a testable level, meanwhile, realizing a thermal or inflationary baryogenesis at a very high…
Dark Energy from pNGB Mediated Dirac Neutrino Condensate
Ujjal Kumar Dey, Tirtha Sankar Ray, Utpal Sarkar
We consider an extension of the Standard Model that provide an unified description of eV scale neutrino mass and dark energy. An explicit model is presented by augmenting the Stand…
Neutrinoless Double Beta Decay in Left-Right Symmetry with Universal Seesaw
Frank F. Deppisch, Chandan Hati, Sudhanwa Patra +2
We discuss a class of left-right symmetric theories with a universal seesaw mechanism for fermion masses and mixing and the implications for neutrinoless double beta () decay…
