Composite Inert Doublet Dark Matter

Abstract

We explore inert doublet dark matter model in a scenario where the scalars including the standard model Higgs originate from an underlying strongly-interacting sector. In particular, we concentrate on a model based on a (formula presented) coset. We show that the parameter space allowed from DM relic density in the usual non-composite inert doublet model can get modified by the interplay of the compositeness scale, the relevant quartic coupling and mass differences of the new scalars. © 2018, Springer International Publishing AG, part of Springer Nature.
