Quantum Field Theory and Unification in AdS 5

  title={Quantum Field Theory and Unification in AdS 5},
  author={Lisa J Randall and Matthew D. Schwartz},
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. † randall… CONTINUE READING
