Dark Matter and 125 GeV Higgs for IDM

TL;DR

This paper investigates a scalar dark matter candidate within the Inert Doublet Model, analyzing how recent LHC data on the 125 GeV Higgs boson, especially diphoton decay measurements, can constrain dark matter properties.

Contribution

It introduces constraints on the Inert Doublet Model's dark matter candidate using recent LHC Higgs data, linking collider observations to dark matter properties.

Findings

LHC Higgs data restricts the parameter space of the IDM dark matter candidate.

Diphoton decay measurements provide significant constraints on dark matter mass and interactions.

The model remains viable within certain parameter ranges consistent with current experimental results.

Abstract

We discuss a scalar Dark Matter candidate from the Inert Doublet Model in light of discovery of a 125 GeV SM-like Higgs boson at the LHC. We explore the possibility of using the recent and future data from LHC experiments, namely the Higgs diphoton decay measurements, to constrain the properties of Dark Matter particles.
