The little Randall-Sundrum model at the large hadron collider

We present a predictive warped model of flavor that is cut off at an ultraviolet scale O(10(3)) TeV. This Little Randall-Sundrurn (LRS) model is a volume-truncation, by a factor y approximate to 6, of the RS scenario and is holographically dual to dynamics with number of colors larger by y. The LRS couplings between Kaluza-Klein states and the Standard Model fields, including the proton constituents, are explicitly calculable without ad hoc assumptions. Assuming separate gauge and flavor dynamics, a number of unwanted contributions to precision electroweak, Zbb and flavor observables are suppressed in the LRS framework, compared with the corresponding RS case. An important consequence of the LRS truncation, independent of precise details, is a significant enhancement of the clean (golden) di-lepton LHC signals, by O(y(3)), due to a larger rho-photon mixing and a smaller inter-composite coupling.
