B-L Conserved Baryogenesis

Pei-Hong Gu, Utpal Sarkar

In the presence of anomaly induced sphaleron process, only a B-L asymmetry can be partially converted to the baryon asymmetry while any B+L asymmetry would be completely erased. Th…

Leptogenesis, Dark Energy, Dark Matter and the neutrinos

Utpal Sarkar

In this review we discuss how the models of neutrino masses can accommodate solutions to the problem of matter-antimatter asymmetry in the universe, dark energy or cosmological con…

Radiative Neutrino Mass, Dark Matter and Leptogenesis

Pei-Hong Gu, Utpal Sarkar

We propose an extension of the standard model, in which neutrinos are Dirac particles and their tiny masses originate from a one-loop radiative diagram. The new fields required by…

Left-Right Symmetric Model of Neutrino Dark Energy

Jitesh R. Bhatt, Pei-Hong Gu, Utpal Sarkar +1

We implemented the neutrino dark energy proposal in a left-right symmetric model. Unlike earlier models of mass varying neutrinos, in the present model the mass parameter that depe…

SO(10) GUT Baryogenesis

Pei-Hong Gu, Utpal Sarkar

Baryogenesis, through the decays of heavy bosons, was considered to be one of the major successes of the grand unified theories (GUTs). It was then realized that the sphaleron proc…

Minimal flavour violations and tree level FCNC

Anjan S. Joshipura, Bhavik P. Kodrani

Consequences of a specific class of two Higgs doublet models in which the Higgs induced tree level flavour changing neutral currents (FCNC) display minimal flavour violation (MFV)…
