Emergent Supersymmetry in Warped Backgrounds

TL;DR

This paper demonstrates that quantum mechanical supersymmetries naturally emerge in the Kaluza-Klein spectrum of linearized gravity within warped backgrounds, crucially influencing the spectral structure of braneworld gravity models.

Contribution

It reveals the emergence of supersymmetries from higher-dimensional invariance and shows they determine the spectral pattern in braneworld models with two branes.

Findings

Supersymmetries emerge in the Kaluza-Klein spectrum due to higher-dimensional invariance.

Emergent supersymmetries determine the spectral structure of braneworld gravity.

The spectral pattern is fully specified by supersymmetries in two-brane models.

Abstract

We show that quantum mechanical supersymmetries are emerged in Kaluza-Klein spectrum of linearized gravity in several warped backgrounds as a consequence of higher-dimensional general coordinate invariance. These emergent supersymmetries play an essential role for the spectral structure of braneworld gravity. We show that for the case of braneworld models with two codimension-1 branes the spectral pattern is completely determined only through the supersymmetries.
