Proton Decay Constraints on Low Scale AdS/CFT Unification

Abstract

Dark matter candidates and proton decay in a class of models based on the AdS/CFT correspondence are discussed. We show that the present bound on the proton decay lifetime is inconsistent with $\mathcal{N}=1$ SUSY, and strongly constrains $\mathcal{N}=0$ non-SUSY, low scale trinification type unification of orbifolded AdS$\otimes S^5$ models.
