Top Quark FB Asymmetry And Flavor Physics
چکیده انگلیسی

CDF and D0 have reported a deviation from the predicted SM forward-backward asymmetry in production at the Tevatron. BSM models that accommodate this observation must incorporate flavor physics and can lead to unacceptable levels of FCNC. We describe recent work on incorporating flavor naturally into these models, both for new physics mediated by scalars and by vectors, using the Minimal Flavor Violation principle. We then describe a new class of models that address the asymmetry, that use derivatively coupled spin-2 mediators. This type of interaction naturally suppresses FCNC.
