The SM Higgs discovery has relied on the following ingredients:
-
An “effective theory”, the SM, which predicted the mass and the couplings of the Higgs particle
-
A > 5 s.d. evidence of signals coincidentally observed by ATLAS and CMS for this particle (FNAL started with a ~3 s.d. indication)
The dominant phenomenological framework remains MSSM but, in absence of evidence for...

A light CP-even scalar is very common in the beyond SM physics. It can be searched at the high-energy colliders or high-intensity experiments via long-lived particles or flavor signals, for instance future $e^+ e^-$ colliders, FASER and DUNE. The signatures might depend on the underlying theories. If sufficiently light, a scalar can also be produced copiously in supernovae, neutron stars, the...

We perform comparative studies for four types of the two Higgs Doublet Models (2HDMs) under the precision measurements of the Standard Model (SM) Higgs observables at the proposed Higgs factories. The exploration for the discovery potential is up to one-loop level. We find 5σ observability from the global fitting in a significant theory parameter space at future Higgs factories. We also...

An essential goal of the Higgs physics program at the LHC and beyond is to explore the nature of the Higgs potential and shed light on the mechanism of electroweak symmetry breaking. An important class of models defining the strength and order of the electroweak phase transition is driven by the Higgs boson coupling to a light new state. This Snowmass white paper points out the existence of a...
