With the recent discovery of the Higgs boson, particle physics enters in a new era. Though the Standard Model (SM) of particle physics proves itself as the most successful framework for understanding the Nature, there are strong evidences, which demonstrate that the SM is yet incomplete. In other words, there are several un-answered questions like: why the neutrino mass should be so tiny, what could be the origin of matter-antimatter asymmetry, what is the nature of dark matter, why are there three generations of fermion families, would there be more Higgses, etc.? All these perhaps point toward a more fundamental aspect of Nature, the study of which remains my main goal of research.
