Collider signals of top quark flavor violation from a warped extra dimension

We study top quark flavor violation in the framework of a warped extra dimension with the Standard Model (SM) fields propagating in the bulk. Such a scenario provides solutions to both the Planck-weak hierarchy problem and the flavor puzzle of the SM without inducing a flavor problem. We find that, generically, $tcZ$ couplings receive a huge enhancement, in particular, the right-handed ones can be O(1%). This results in BR(t→cZ) at or above the sensitivity of the Large Hadron Collider (LHC). At the International Linear Collider (ILC), single top production, via e⁺e^-→tc̄, can be a striking signal for this scenario. In particular, it represents a physics topic of critical importance that can be explored even with a relatively low energy option, close to the $tc$ threshold. At both the LHC and the ILC, angular distributions can probe the above prediction of dominance of right-handed couplings.
