Description
In the context of warped five-dimensional models formulated to understand the physics beyond the Standard Model (SM), we will discuss the prediction of a continuum of Kaluza-Klein modes on top of the SM zero modes, with a mass gap. We compute the Green’s functions for gauge bosons and describe how the continuum is reached from a discretized theory. We also study the Green's functions for the graviton and the radion, as well as the couplings of these fields with SM matter fields. This work is based on Refs. [1-3].
