Dark Matter Theory ( Relic Abundance, Direct & Indirect detect)

Neutrino Masses, Leptonic CP Violation

Theories Beyond Standard Model, Origin of Matter Antimatter Asymmetry and Asymmetric Dark Matter

         At present I am working on various aspects in the interface of particle physics and cosmology.  As we know standard model (SM) of particle physics, which is based on the gauge group SU(3)c x SU(2)L x U(1)Y , is the most successful one to explain the strong, electromagnetic and weak forces of nature. With the recent discovery of Higgs scalar at Compact Muon Solenoid (CMS) and at A Toroidal LHC ApparatuS (ATLAS) experiments at CERN-LHC the SM seems to be complete. However, it does not explain the tiny masses of the three active neutrinos for which we have strong experimental evidence. Moreover, it does not explain many other aspects which are related to the large scale structure of the observed Universe. In particular, some fundamental questions like "How observed matter is generated in a standard Big-Bang cosmology?", "What constitutes the dark matter and dark energy?" and so many of this list. We try to answer some of these questions by using current experimental evidences. For example, non-zero masses of the neutrinos, the origin of matter antimatter asymmetry, the particle physics candidate of dark matter and its direct, indirect and collider signature etc.
