After the long-awaited discovery of the Higgs boson at the LHC, the next step is now to observe the signs of new physics. Supersymmetry, being perhaps the most studied candidate of new physics, might still be hiding pretty successfully under the Standard Model background, or might be beyond the reach of the LHC. A Higgs of mass 126 GeV is within the MSSM preferred mass window but at the same time it is a little on the heavy side to challenge the supersymmetric solution to the hierarchy problem. Higgs couplings to gauge bosons and fermions seem to be in good agreement with the expected Standard Model couplings and we might have to wait for the ILC to measure them more precisely to see the effects of any new physics. Dark matter experiments are yet to observe the signs of a weakly interacting massive particle that makes up a large percentage of the universe. With the recent discovery of the Higgs boson, and many small hints for physics beyond the Standard Model, it is certainly an exciting time for particle physicists. I share this excitement and have a range of interests which can be broadly categorized as the phenomenology of beyond the Standard Model physics.

Here is a brief list of the topics I work on:

  • New physics at the TeV scale, with a special focus on supersymmetric models. Signatures of new physics in current & future collider and dark matter experiments.
  • Models of electroweak symmetry breaking with a special focus on two Higgs doublet models. Theory and phenomenology of models with extended Higgs sectors and their collider signatures.
  • Kinematic variables and mass measurement techniques for new physics at the LHC.
