Abstract
The CP parity of the Higgs boson and the details of the electroweak symmetry breaking are the two crucial ingredients to understand the matter-antimatter asymmetry in our universe. Electroweak baryogenesis is an intriguing solution to the puzzle of this unexplained observed asymmetry because of its testability at present and near future collider experiments. The possibilities of testing CP phase in the Two-Higgs-Doublets Models (2HDMs) and the generation of a strong first-order electroweak phase transition (SFOEWPT) in the real singlet model at the future high luminosity LHC are studied. In addition to the specific extensions to the Standard Model (SM), I also study the sensitivity of the future 100 TeV collider in probing the Wilson coefficients of the dimension 6 operators related to the Higgs sector using the effective field theory (EFT) approach. The observed non-zero neutrino mass is another phenomenon that the SM fails to explain. The Left-Right Symmetric Model (LRSM) proposes a natural explanation of the smallness of the neutrino mass and its connection to the high scale spontaneous parity violation. I study the prospects of searching the heavy right-handed neutrinos and measuring the mixing between the light and heavy neutrinos in the framework of the minimal LRSM at the future 100 TeV hadron collider.
