Can the 750 GeV diphoton LHC excess be due to a radion-dominated state?

Abstract

We discuss the possibility of interpreting the 125 GeV scalar boson and the 750 GeV diphoton excess recently reported by the ATLAS and CMS experiments as a Higgs-dominated and a radion-dominated states respectively in a stabilized brane-world model. It is shown that in the simplest variant of the model, where only the gravitational degrees of freedom propagate in the bulk, the production cross section of the radion-dominated state with mass 750 GeV turns out to be too small in the allowed region of the model parameter space for explaining the nature of the excess in this approach.
