Using two different warped five-dimensional (5D) models with two
branes along the extra dimension, we study the Green’s functions and the spectral
properties of some of the fields propagating in the bulk. While the first
model has a discrete spectrum of Kaluza-Klein (KK) modes, the second one
has a continuous spectrum above a mass gap. We also study the positivity of the
spectral functions, as well as the coupling of the graviton and the radion with
SM matter fields
