Could the excess seen at 124-126 GeV be due to the Randall-Sundrum Radion?

TL;DR

The paper explores whether the excess observed at 124-126 GeV in Higgs searches could be explained by the Randall-Sundrum radion, which has distinct coupling properties affecting production and decay rates.

Contribution

It proposes that the Randall-Sundrum radion can account for the observed excess and matches experimental data with specific coupling parameters.

Findings

Radion can explain the 124 GeV excess in CMS data.

Radion's enhanced couplings to photons and gluons alter decay rates.

Model fits the data with a radion scale around 0.68 TeV.

Abstract

Current Higgs boson searches in various channels at the LHC point to an excess at around 124-126 GeV due to a possibly standard-model-like Higgs boson. If one examines more closely the channels (\gamma\gamma, WW*, and ZZ*) that have excess, this "Higgs boson" may be the Randall-Sundrum radion \phi. Because of the trace anomaly the radion has stronger couplings to the photon and gluon pairs. Thus, it will enhance the production rates into gg and \gamma\gamma while those for WW*, ZZ* and b\bar b are reduced relative to their standard-model values. We show that it can match well with the data from CMS for m_\phi = 124 GeV and the required scale \Lambda_\phi ~ <\phi > is about 0.68 TeV.
