Descripción
I will give an overview of the phenomenological aspects of a simplified dark matter scenario where the mediator is a new extra fermion (chiral or vector-like) carrying leptonic quantum number and the dark matter candidate is either scalar or vector. The extra lepton and the dark matter are odd under a Z^2 symmetry, hence the leptonic mediator can only interact with the dark matter state and standard model leptons of different flavours. In this study we will focus on scenarios where the new heavy lepton is electrically charged. We consider tree- and loop-level constraints from direct and indirect detection, electroweak precision tests, relic density, (g-2) of electron and muon, lepton flavour violation and collider signatures at the Large Hadron Collider. We determine the excluded regions for representative benchmark scenarios, characterized by different assumptions about the coupling between the heavy lepton, the dark matter and standard model leptons.
