We discuss a simple theory for physics beyond the Standard Model where a Majorana dark matter is predicted from anomaly cancellation. We discuss in detail the minimal theory where the baryon number is a local symmetry spontaneously broken at the low scale. The correlation between the cosmological constraints on the dark matter relic density, the direct detection and collider bounds is...
Models of inelastic (or pseudo-Dirac) Dark Matter (DM) commonly assume an accidental symmetry between the left-handed and right-handed mass terms in order to suppress diagonal couplings. We point out that this symmetry is unnecessary, because for Majorana fermions the diagonal couplings are not strongly constrained. Removing the requirement of such an accidental ad-hoc symmetry instead relaxes...
We discuss a class of theories that predict a fermionic dark matter candidate from gauge anomaly cancellation.
As an explicit example, we study the predictions in theories where the global symmetry associated with baryon number is promoted to a local gauge symmetry.
In this context the symmetry-breaking scale has to be below the multi-TeV scale in order to be in agreement with the...
