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.
Key words:
supersymmetry; boundary condition; extra dimension.
