We consider gauge bosons in the bulk of AdS5 in a two-brane theory that addresses the hierarchy problem. We demonstrate that one can do a perturbative calculation above the IR scale associated with the second brane. We show such a theory can be consistent with gauge coupling unification at a high scale. We discuss subtleties in this calculation and show how to regulate consistently in a bounded AdS5 background. Our regularization is guided by the holographic dual of the calculation.

• The Bulk RS KK-gluon at the LHC (2007, background): “However models in which the SM fermions and gauge bosons propagate throughout all five dimensions [2 – 4] can have attractive features such as suppressing flavor-changing neutral currents, explaining the hierarchy of fermion masses [3], and allowing gauge coupling unification [5].”
