Phenomenology of Radion in Randall-Sundrum Scenario

Abstract

The success of the Randall-Sundrum scenario relies on stabilization of the modulus field or the radion, which is the scalar field about the background geometry. The stabilization mechanism proposed by Goldberger and Wise has the consequence that this radion is lighter than the graviton Kaluza-Klein states so that the first particle to be discovered is the radion. In this work, we study in details the decay, production, and detection of the radion at hadronic, $e^{+}{e}^{-}$, and $\gamma \gamma$ colliders.
