Flavor-specific top quark models with distinctive signatures

Dark matter interactions preferentially involving the top quark

Abstract

We review scenarios of physics beyond the Standard Model in which the top quark plays a special role. Models that aim at the stabilization of the weak scale are presented together with the specific phenomenology of partner states that are characteristic of this type of model. Further, we present models of flavor in which the top quark is singled out as a special flavor among the SM ones. The flavor and collider phenomenology of these models is broadly presented. Finally, we discuss the possibility that dark matter interacts preferably with the top quark flavor and broadly present the dark matter phenomenology of these scenarios, as well as collider and flavor signals.
