Higgs measurements and searches as a portal to physics beyond the Standard Model
The measurement of Higgs properties poses significant constraints on physics beyond the Standard Model. These are compared with direct searches of additional scalar states of an extended Higgs sector. As a simple example, we consider a scalar singlet coupled to the other particles only through its mixing with the Higgs boson, which appears in several motivated extensions of the Standard Model. The prospects for the discovery of a generic singlet at the various stages of the LHC, as well as at future high-energy colliders, are studied, and the reach of direct searches is compared with the precision attainable with Higgs couplings measurements. The results are then applied to the NMSSM and Twin Higgs.
