The discovery of the Higgs Boson presents us with a rich experimental program. In particular its unique sensitivity to the potential existence of new, light, weakly coupled particles can give rise to a large variety of exotic Higgs decays. The explicit search for those decays presents a largely untapped discovery opportunity of new physics for the LHC collaborations. I will describe the...

Several BSM scenarios suggest the existence of new light bosons weakly coupled to most SM particles. Examples of such models are SUSY with "dark" sector or scenarios with extended Higgs sector, e.g. NMSSM. In these models, new bosons can be produced either in the Higgs decays or as part of SUSY cascades. Exotic decays of the Higgs can either hide the Higgs boson from standard searches or...

The existence of a light vector-like lepton can contribute to the SM Higgs decays. In this talk we analyse its effect in the SM Higgs to ZZ* channel assuming the mixing of the vector-like lepton and the SM muon, motivated from the possible explanation of muon g-2 anomaly. We also show the bound from the current LHC result in terms of general parameters of the vector-like lepton.

The “Lonely higgs” picture has put considerable pressure on theories that aim to solve the hierarchy problem. The focus has now shifted to the determination of its detailed properties and in particular whether or not it possesses any anomalous couplings not predicted by the Standard Model by extensive analysis of the higgs production and decays. **The dominant contribution to the $H \to \gamma...

We show that the addition of a fourth generation with vector-like quarks to the minimal supersymmetric standard model (MSSM) can raise the predicted value of the physical Higgs mass by mixing with the top sector, a point not previously emphasized in the literature. In the presence of mixing, for A-terms and soft masses around 900 GeV, the Landau pole for the top Yukawa can be pushed above the...

The baryonic matter-antimatter asymmetry in the universe is a well known fact, and measured to be $n_B-n_{\overline
B}\sim6\cdot10^{-10}n_\gamma$. Standard Leptogenesis is among the simplest and most natural theories to explain the asymmetry, making use of the
family of three heavy right-handed Majorana neutrinos, already well motivated to explain the active neutrino masses, which puts the...
