The Flavour Portal to Dark Matter

Understand

We present a class of models in which dark matter (DM) is a fermionic singlet under the Standard Model (SM) gauge group but is charged under a symmetry of flavour that acts as well on the SM fermions.

• Interactions between DM and SM particles are mediated by the scalar fields that spontaneously break the flavour symmetry, the so-called flavons.
• In the case of gauged flavour symmetries, the interactions are also mediated by the flavour gauge bosons.
• We first discuss the construction and the generic features of this class of models.
