TL;DR
This paper investigates the potential for detecting the radion, a scalar field predicted by the stabilized Randall-Sundrum model, through exclusive production processes at the CERN LHC, highlighting the dominance of diffractive production.
Contribution
It provides the first detailed analysis of radion production in exclusive electromagnetic and diffractive hadron collisions at the LHC, emphasizing the significance of diffractive processes.
Findings
Diffractive radion production is dominant at the LHC.
Radion detection via exclusive processes is feasible at CERN.
The study offers predictions for radion signals in LHC experiments.
Abstract
In the Randall-Sundrum (RS) scenario the compactification radius of the extra dimension is stabilized by the radion, which is a scalar field lighter than the graviton Kaluza-Klein states. It implies that the detection of the radion will be the first signature of the stabilized RS model. In this paper we study the exclusive production of the radion in electromagnetic and diffractive hadron - hadron collisions at the LHC. Our results demonstrate that the diffractive production of radion is dominant and should be feasible of study at CERN LHC.
