| contents | In this work, we study an extension of the Standard Model which includes a new massive vector field in the fundamental representation of SU(2)_L. The neutral component of the new vector field is a natural dark matter candidate. We compute the Annihilation Cross Section with Sommerfeld Enhancement and the Photon Flux arising from Dark Matter annihilation events. We found that the model exhibits a resonant mass part around the range of 2-10 TeV. This resonance is influenced by the choice of portal Higgs coupling parameter. We show that these predictions can be partially tested by CTA in the near future. |
