Research activities of the High Energy Physics Group include Phenomenology of Particle Physics Beyond the Standard Model with emphasis on aspects of Electroweak Symmetry Breaking and Higgs Mechanism, CP violation, Matter-Antimatter Asymmetry of the Universe, Neutrino Physics and Issues related to cosmological Inflation, perturbative and non-perturbative QCD, low-energy effective field theory and hadron physics.

On Experimental High Energy Physics, we are collaborating with the Belle/Belle II and BaBar experiments for research involving B-mesons, CP violation and physics search beyond Standard Model. We are also collaborating with the Fermi National Accelerator Laboratory (FNAL) on research in Neutrino Physics.
