Special seminar i high energy physics about novel ways to probe potential new physics beyond the Standard Model within a model independent (Effective Field Theory- higher dimensional operators) and model dependent setting (Lepton-specific two Higgs-doublet model).

The discovery of the 125 GeV Higgs boson at the Large Hadron Collider (LHC) ushered in a new chapter in the study of fundamental structure of particle interactions. With the data collected from Run-I of the LHC and the ongoing Run-II, efforts are being directed towards shaping a better understanding of the couplings of the 125 GeV scalar to the other Standard Model (SM) gauge bosons and fermions. Any deviation of these couplings from their SM counterparts stands as a smoking gun signal to the new physics beyond the SM framework. In this talk we shall explore some such instances of probing the new physics within a model independent (Effective Field Theory- higher dimensional operators) and model dependent setting (Lepton-specific two Higgs-doublet model). The focus shall be to exemplify how a judicious choice of kinematic observables can help one to single out certain features of the kind of Beyond Standard Model (BSM) physics one is confronted with.
