Constraining Inert Dark Matter by R_{\gamma\gamma} and WMAP data

TL;DR

This paper analyzes how LHC Higgs data and WMAP measurements constrain the Inert Doublet Model, significantly limiting its parameter space and providing insights into dark matter properties.

Contribution

It combines collider and cosmological data to set new, strong constraints on the Inert Doublet Model's parameters, improving upon previous experimental bounds.

Findings

Strong limits on IDM parameter space from combined data

Constraints comparable to XENON100 for certain dark matter masses

Enhanced understanding of IDM viability with current measurements

Abstract

We discuss the constraints on the Dark Matter coming from the LHC Higgs data and WMAP relic density measurements for the Inert Doublet Model (IDM), which is one of the simplest extensions of the Standard Model providing a Dark Matter (DM) candidate. We found that combining the diphoton rate R_{\gamma\gamma} and the \Omega_{DM}h^2 data one can set strong limits on the parameter space of the IDM, stronger or comparable to the constraints provided by XENON100 experiment for low and medium DM mass.
