Journal Article

Using a five dimensional (5D) warped model with two branes along the extra dimension, we study the Green's functions for gauge bosons with a mass gap mg=ρ/2 and a continuum for s>mg2. We find that the Green's functions exhibit poles in the second Riemann sheet of the complex s plane, denoting the existence of broad resonances. The positivity of the spectral functions is also analyzed. Finally, it is shown how the Green's functions can modify some Standard Model processes in pp collisions.
