Description
I discuss the anomalously large asymmetry in top-antitop-quark production within Randall-Sundrum models. Kaluza-Klein gluons generically have the potential to generate a large forward-backward asymmetry at tree level. In models with an anarchic flavour structure, however, their coupling to the light quarks inside the proton is strongly suppressed. I show that even though this suppression is lifted at one-loop level, the large asymmetry cannot be explained in a natural framework of warped extra dimemsions.
