Leptonic Scalar Dark Matter and Higgs Phenomenology at Hadron Colliders

Prof. Chung Kao

We adopt a simple model with self interacting dark matter and focus on the effects of Sommerfeld enhancement. In this model, the dark matter candidate is a leptonic scalar particle with a light mediator. We have found favored regions of the parameter space with proper masses and coupling strength generating a relic density that is consistent with the observed CDM relic density. Furthermore, this model satisfies the constraints of recent direct searches and indirect detection for dark matter as well as the observed small-scale structure of the Universe. Furthermore, we present the prospects of discovering the top quark decay into a charm quark and a Higgs boson (
