In this talk I will focus mainly on the structure of the Higgs couplings in different beyond the Standard Model scenarios. Recent observations at the Large Hadron Collider (LHC) gives us the motivation to look for scenarios with more than one Higgs doublet. In this context, I will address 2-and multicomponent Higgs extensions from phenomenological viewpoint. I will also talk about the effects of including higher dimensional operators in such theories and its consequences at LHC and Flavor Physics.
