Description
We consider a minimal framework which features a Majorana fermion as the
dark matter particle and a scalar that mediates the coupling to light
fermions. In this scenario the annihilation rate into two fermions and
one gauge boson as well as the interaction rate with nuclei can be
significantly enhanced while avoiding the strong limits on new physics
from collider experiments. We discuss in this talk the limits on the
parameters of the model from indirect, direct and collider dark matter
searches as well as the prospects to probe this scenario in future experiments.
