The scalar Singlet-Triplet Dark Matter Model
  We consider a model for cold dark matter, which combines a real scalar
singlet and a real scalar $SU(2)_L$ triplet field, both of which are residing
in the odd representation of a global $Z_2$ symmetry. The parameter space of
the model is constrained by the inferred dark matter abundance from the WMAP
and Planck data, the most recent results from the direct dark matter search
experiment LUX, the Z boson decay width from LEP-I and perturbativity of the
coupling parameters. The phenomenology of the remaining parameter space is
studied. We find that the model allows for DM masses near the electroweak scale
and a variety of decay scenarios.
