WIMP Dark Matter in Composite Higgs Models and the Dilaton Portal

Understand

We study under which conditions a scalar particle is a viable WIMP Dark Matter candidate with Higgs and dilaton interactions.

• The theory is a composite Higgs model with top partial compositeness where both the Higgs and the Dark Matter candidate arise as pseudo Goldstone boson of the coset SO(6)/SO(5) from a new physics sector.
• We highlight the role of the dilaton in direct and indirect searches.
• We find that a Dark Matter particle with a mass around 200-400 GeV and a relatively light dilaton are a fair prediction of the model.
