Higgs phenomenology and dark matter with vector-like leptons
We study an extension of the standard model with a vector-like generation of leptons. This model provides a viable dark matter candidate and a possibility to enhance the Higgs decay rate into a pair of photons.
The plot on the left illustrates this for a region of parameter space where the dark matter relic density is controlled through the co-annihilation mechanism. The full paper, written together with Aniket and Carlos, is available here.
