On Anomaly-Free Dark Matter Models

Understand

We investigate the predictions of anomaly-free dark matter models for direct and indirect detection experiments.

• We focus on gauge theories where the existence of a fermionic dark matter candidate is predicted by anomaly cancellation, its mass is defined by the new symmetry breaking scale, and its stability is guaranteed by a remnant symmetry after the breaking of the gauge symmetry.
• We find an upper bound on the symmetry breaking scale by applying the relic density and perturbative constraints.
• The anomaly-free property of the theories allows us to perform a full study of the gamma lines from dark matter annihilation.
