ABSTRACT

The Inert doublet model is an extension of the Standard Model by one extra scalar, with identical gauge quantum numbers as the Standard Model Higgs doublet, but charged under a discrete unbroken symmetry. The model offers a very rich phenomenology and could lead to signatures in electroweak precision observables or collider experiments. Furthermore, the lightest particle of the extended scalar sector is a dark matter candidate. In this talk we review the dark matter phenomenology of the model, concretely the dark matter thermal production, the direct detection signals and the indirect detection signals, with emphasis on the generation of sharp gamma-ray spectral features via internal bremmstrahlung or via quantum effects.
