The mechanism of Electroweak Symmetry Breaking (EWSB) is one of the least understood aspects of the particle physics today. With the recent discovery of the Higgs Boson at the Large Hadron Collider (LHC), it is now confirmed that the Higgs mechanism proposed to understand the EWSB is the right direction. By now all the expected decay channels of the Higgs boson is observed, and no evidence of anything other than what is predicted in the Standard Model (SM) is seen. While this gives us huge confidence in the SM based on the gauge symmetry principle as the theoretical framework of elementary particle dynamics at the electroweak scale (~ 100 GeV), there are ample reasons to look beyond.

Our main interest presently is in the Phenomenology of Particle Physics Beyond the Standard Model with emphasis on aspects of Electroweak Symmetry Breaking and Higgs Mechanism, and CP violation. Considering model specific scenarios, we investigate the supersymmetric models like the MSSM and NMSSM with CP-violating Higgs sector, 2HDM and other multi-Higgs scenarios with and without CP violation in the Higgs sector. Apart from such specific models, generic analyses in a model independent way to understand dynamics beyond the scope of Standard Model in cases with composite Higgs scenarios, Effective Lagrangian method to investigate non-standard Higgs couplings with fermions and gauge bosons, and the self-couplings of the Higgs bosons, etc are considered.
