Abstract:
In Randall-Sundrum models with gauge bosons and fermions in the extra-dimensional bulk, it is possible to build models of flavor by localizing the fermions in the extra dimension. Since the Higgs boson must be localized at or close to the TeV scale fixed point, heavier fermions must be localized close to this brane. The first Kaluza-Klein excitations of the gauge bosons are also TeV-localized, so they have stronger couplings to heavier fermions leading to tree-level flavor-violating couplings. We investigate the potential of the Large Hadron Collider to observe flavor violation in single top production at very high invariant masses, in addition to the observation of the corresponding t-t[over] resonance. We conclude that the Large Hadron Collider will be able to observe tree-level flavor violation in single top production, probing Kaluza-Klein masses at least as large as 2 TeV, as well as a very interesting region of the parameters.
