Gamma Lines from Majorana Dark Matter
  We discuss simple models which predict the existence of significant gamma-ray
fluxes from dark matter annihilation. In this context the dark matter candidate
is a Majorana fermion with velocity-suppressed tree-level annihilation into
Standard Model fermions but unsuppressed annihilation into photons. These gamma
lines can easily be distinguished from the continuum and provide a possibility
to test these models.
