Top quark decays in extended models

Description

The top quark decays are of particular interest as a means to test the standard model (SM) predictions. These include the dominant t -> bW, the Cabibbo-Kobayashi-Maskawa (CKM)-suppressed process t -> cWW, and the rare decays t -> cZ and t -> c gamma. They are highly suppressed and they become an excellent window to probe the predictions of theories beyond the SM. In this work we evaluate the effects from new physics on the rare decays t -> cZ and t -> c + gamma within the context of an alternative left-right symmetric model.
