"Natural Dark Matter in Unnatural Theories"

This event is part of the HET Seminar Series.

Abstract: The thermal relic abundance of Dark Matter motivates the existence of new electroweak scale particles, independent of naturalness considerations. However, most unnatural Dark Matter models do not ensure the presence of new colored particles. The result is a challenging LHC phenomenology. Here, we present a class of models with scalar electroweak doublet Dark Matter that require a host of colored particles at the TeV scale. In these models, the Higgs boson is apparently fine-tuned, but the Dark Matter doublet is kept light without any additional fine-tuning. We briefly discuss the phenomenological implications of such theories.
