Graviton modes in multiply warped geometry

TL;DR

This paper explores how multiply warped geometries can modify graviton spectra and couplings, potentially resolving the limitations of the Randall-Sundrum model in explaining the hierarchy problem despite null results in LHC searches.

Contribution

It demonstrates that multiple warping in extra dimensions alters graviton properties, providing a natural solution to the hierarchy problem within warped geometry models.

Findings

Multiple warping changes graviton mass spectrum.

Modified graviton couplings to Standard Model fields.

Potential resolution of LHC null results in graviton searches.

Abstract

The negative results in the search for Kaluza-Klein graviton modes at the LHC, when confronted with the discovery of the Higgs, has been construed to have severely limited the efficacy of the Randall-Sundrum model as an explanation of the hierarchy problem. We show, though, that the presence of multiple warping offers a natural resolution of this conundrum through modifications in both the graviton spectrum and their couplings to the Standard Model fields.
