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 > m2g
. 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.
