TL;DR

This paper investigates the production and decay of a radion in the Randall-Sundrum model at the LHC, analyzing how to distinguish it from the Higgs boson and other scalar particles.

Contribution

It provides constraints on the model parameters based on LHC Higgs search results and explores methods to differentiate the radion from similar scalars in other theories.

Findings

Constraints on radion model parameters from LHC data

Potential signatures to distinguish radion from Higgs and supersymmetric scalars

Analysis of radion production and decay channels at the LHC

Abstract

We study production and decay of a radion predicted in the Randall-Sundrum model at the LHC. The radion is a scalar particle and its production and decay channels are quite similar to those of the Higgs boson. We find constraints on the model parameter space taking account of the results of the Higgs boson search at the LHC. We also study a possibility discriminating the radion from the scalar particles in the other model such as the supersymmetric standard model at the LHC experiments.
