We investigate the parameter space of the Inert Doublet Model, which is a straightforward extension of the SM in the scalar sector. We apply a set of constraints both from the theoretical and experimental side to extract and determine allowed regions of parameter space. These constraints put strong limits on both masses and couplings of the new particles. We also present a set of benchmarks for the current LHC run. This work is based on [1, 2].

Status of the Inert Doublet Model of dark matter after Run-1 of the LHC
The Inert Doublet Model (IDM) is one of the simplest extensions of the Standard Model that can provide a viable dark matter (DM) candidate. Despite its simplicity, it predicts a versatile
Consistency of a gauged two-Higgs-doublet model: Scalar sector
We study the theoretical and phenomenological constraints imposed on the scalar sector of the gauged two Higgs doublet model proposed recently as a variant of the popular inert Higgs doublet model of
Compressing the Inert Doublet Model
The Inert Doublet Model relies on a discrete symmetry to prevent couplings of the new scalars to Standard Model fermions. We found that this stabilizes the lightest inert state, which can then
Benchmarking the Inert Doublet Model for e+e− colliders
A bstractWe present benchmarks for the Inert Doublet Model, a Two Higgs Doublet Model with a dark matter candidate. They are consistent with current constraints on direct detection, including the

Anatomy of the inert two-Higgs-doublet model in the light of the LHC and non-LHC dark matter searches

Dilepton constraints in the Inert Doublet Model from Run 1 of the LHC
Searches in final states with two leptons plus missing transverse energy, targeting supersymmetric particles or invisible decays of the Higgs boson, were performed during Run 1 of the LHC. Recasting
The Inert Doublet Model and Its Phenomenology
The single Higgs doublet in the standard model (SM) may be the simplest way of introducing electroweak symmetry breaking, but SM extensions with more scalar doublets are not excluded. A special case
Temperature evolution of physical parameters in the Inert Doublet Model
Inert Doublet Model is a minimal extension of the Standard Model with the second scalar doublet that may provide a Dark Matter candidate. In this paper we consider different variants of the evolution
Trilepton signals in the inert doublet model
In this work, a set of representative benchmark scenarios in which all applicable constraints are satisfied are presented, and it is shown that in some of these scenarios, it is possible to obtain a signal at the 5{sigma} significance level or better with integrated luminosity of 300 fb{sup -1}.
