Abstract Models with non-minimal Higgs sectors represent a mainstream direction in
theoretical exploration of physics opportunities beyond the Standard Model. Extended scalar …

This Report summarizes the results of the activities of the LHC Higgs Cross Section Working
Group in the period 2014–2016. The main goal of the working group was to present the state …

We briefly survey several typical CP-conserving two-Higgs-doublet models (2HDMs) in light
of current experiments. First we derive the masses and couplings of the mass eigenstates …

A bstract The ATLAS experiment at the LHC has measured the Higgs boson couplings and
mass, and searched for invisible Higgs boson decays, using multiple production and decay …

We investigate the LHC phenomenology of a model where the Standard Model (SM) scalar
sector is extended by two real scalar singlets. A\({{\mathbb {Z}} _2}\otimes {{\mathbb {Z}} …

A bstract The discovery of the Higgs boson by the LHC experiments ATLAS and CMS has
marked a milestone for particle physics. Yet, there are still many open questions that cannot …

The Compact Linear Collider (CLIC) is a mature option for the future of high energy physics.
It combines the benefits of the clean environment of $ e^+ e^-$ colliders with operation at …

A bstract The N2HDM is based on the CP-conserving 2HDM extended by a real scalar
singlet field. Its enlarged parameter space and its fewer symmetry conditions as compared to …

A bstract The Complex singlet extension of the Standard Model (CxSM) is the simplest
extension that provides scenarios for Higgs pair production with different masses. The model …

We investigate unitarity bounds in the most general two Higgs doublet model without a
discrete Z 2 symmetry nor CP conservation. S-wave amplitudes for two-body elastic …
