Light signals from spin one tensor dark matter

Abstract

In this work we report on some observables associated with the annihilation of dark matter, modeled as a spin one real field in the antisymmetric tensor representation. This formulation has the interesting feature that stability is achieved without the introductionof ad hoc symmetries, as reported by Cata and Ibarra in 2014. In this model, the coupling to photons ocurrs through a Higgs portal term. The expression for the cross section in the photon scattering is calculated as well as their energy and the gamma ray flux.
