Abstract

Higgs physics beyond the Standard Model (SM) is presented in the context of an underlying strong dynamics of electroweak symmetry breaking (EWSB) as given by composite Higgs models. Subsequently, the study of New Physics (NP) effects in a more model-independent way through the effective Lagrangian approach is briefly sketched before moving on to the investigation of NP through Higgs coupling measurements. Depending on the precision on the extracted couplings, NP scales up to the TeV range can be probed at the high-luminosity option of the LHC, if the coupling deviations arise from mixing effects or from some underlying strong dynamics.
