TL;DR
This paper explores gauge bosons in a two-brane AdS5 setup, demonstrating potential for gauge coupling unification at high scales while addressing regularization challenges through holographic duality.
Contribution
It introduces a consistent regularization method for gauge coupling calculations in bounded AdS5, linking holography with unification scenarios.
Findings
Gauge coupling unification is achievable in two-brane AdS5 models.
A holographically guided regularization scheme is proposed.
The model addresses hierarchy problem and unification simultaneously.
Abstract
We consider gauge bosons in the bulk of AdS5 in a two-brane theory that addresses the hierarchy problem. 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.
