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

We analyze one-loop vacuum stability, perturbativity, and phenomenological constraints on
a complex singlet extension of the standard model scalar sector containing a scalar dark …

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 consider a simple extension of the Standard Model (SM) by a complex scalar doublet
and a singlet along with three sterile neutrinos. The sterile neutrinos mix with the SM …

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 …

Extensions of the Higgs sector of the Standard Model allow for a rich cosmological history
around the electroweak scale. We show that besides the possibility of strong first-order …

We present the first version of a new tool to scan the parameter space of generic scalar
potentials, ScannerS (Coimbra et al., ScannerS project., 2013). The main goal of ScannerS …

A fermion dark matter candidate with a relic abundance set by annihilation through a
pseudoscalar can evade constraints from direct detection experiments. We present …

A feature of the inert doublet model (IDM) is to provide a dark matter candidate together with
an alteration of both direct and indirect collider constraints that allow for a heavy Higgs …
