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 different mass gaps for all particles: gauge bosons, fermions, graviton, radion and Higgs boson. In particular, we will study the existence of resonance effects in gauge bosons. The model can be considered as a modelization in five dimensions of gapped unparticles. We compute the Green's functions and show how they can modify some SM processes. We also discuss some applications for Dark Matter. This work is based on Refs. [1-2].
