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…
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)…
A possible disk mechanism for the 23d QPO in Mkn~501
J. H. Fan, F. M. Rieger, T. X. Hua +7
Optically thin two-temperature accretion flows may be thermally and viscously stable, but acoustically unstable. Here we propose that the O-mode instability of a cooling-dominated…
