Precocious Diphoton Signals of the Little Radion at Hadron Colliders

TL;DR

This paper explores how Little Randall-Sundrum models predict a significantly enhanced diphoton signal from the radion at hadron colliders, with implications for current and future collider experiments.

Contribution

It analyzes the radion's diphoton signal enhancement in Little RS models and assesses collider data's ability to detect or constrain this signal.

Findings

Tevatron data constrains the radion parameter space

7 TeV LHC run can significantly probe the radion signal

Diphoton channel is key for discovering light radions or dilatons

Abstract

In Little Randall-Sundrum models, the bulk couplings of the radion to massless gauge fields can yield a greatly enhanced diphoton signal at hadron colliders. We examine the implications of the Tevatron data for the Little radion and also show that the 7 TeV run at the Large Hadron Collider will have an impressive reach in this channel. The diphoton signal is crucial in the search for a light radion, or the dual dilaton, and can potentially probe the ultraviolet scale of the theory.
