Description
We explore a simple extension of the Standard Model which incorporates a vector field in the fundamental representation of SU(2)L as the only non-standard degree of freedom. This kind of field may appear in models where a new strong sector produce the Higgs doublet as a composite state but does not break the chiral symmetry. We study the model in the presence of a discrete Z2 symmetry. As a consequence, the neutral CP-even component of the new vector field becomes a Dark Matter candidate. We constraint the values of the model parameters from unitarity bounds, h → γγ measurements, electroweak precision tests, cosmological observations and current dark matter searches.
