Unitarity constraints on the stabilized Randall-Sundrum scenario
The recently proposed stabilization mechanism of the Randall-Sundrum metric gives rise to a scalar radion, which couples universally to matter with a weak interaction (1 TeV) scale. Demanding that gauge boson scattering as described by the effective low-energy theory be unitary up to a given scale leads to significant constraints on the mass of such a radion.
