Searching for new physics at the Large Hadron Collider in the Higgs era

The recent discovery of a Higgs-like boson at the Large Hadron Collider (LHC) implies a unique opportunity to study its properties and to search for new physics beyond the Standard Model (SM) that might be associated with it. The purpose of my research program is to search for any possible non-SM feature of this new particle and to use the current and upcoming data from the LHC and other experiments as guidance for constructing models of physics beyond the SM. One part of my research program focuses on the study of possible exotic Higgs decays that can be searched for at the LHC. In the analysis of these decays I will perform detector level simulations of the signals and the relevant backgrounds, determine the optimal kinematic and geometric cuts and estimate the possibility and viability of performing proper experimental searches for these exotic Higgs decays. The other part of my research program aims at constructing non-minimal extensions of the SM. In one project the Higgs measurements are used in order to determine the set of effective operators that could most naturally account for the present data. The microscopic degrees of freedom from which those effective operators can be generated are then identified. Another project aims at constructing a new class of ultraviolet completions of certain low energy effective models that I have previously considered in my research. A detailed phenomenological study of all the constructed models will also be performed.
