Description
Motivated by the absence of WIMP signal in the recent direct and indirect
detection searches, we consider a
scenario where the breaking of an abelian symmetry generates the
annihilation of hypercharge bosons into the
Nambu-Goldstone of the theory, the dark matter candidate.
The couplings are generated by loops of heavy fermions which masses are
also determined
by the scale of the $U(1)$ breaking. In other words, all the parameters of
the model are dynamically generated and naturally leads
to the right amount of dark matter for a breaking scale of the order of
unification scale and a very light Nambu-Goldstone boson
at the keV range.
