Two Graviton Production at $e^{+}{e}^{-}$ and Hadron Hadron Colliders in the Randall-Sundrum Model

Abstract

We compute the pair production cross section of two Kaluza Klein modes in the Randall-Sundrum model at $e^{+}{e}^{-}$ and hadron hadron colliders. These processes are interesting because they get dominant contribution from the graviton interaction at next to leading order. Hence they provide a nontrivial test of the low scale gravity models. All the Feynman rules at next to leading order are also presented. These rules may be useful for many phenomenological applications including the computation of higher order loop corrections.
