Three family N=1 SUSY models from Zn orbifolded AdS/CFT

We present an analysis of compactifications of the type IIB superstring on AdS5×S5/Γ, where Γ is an Abelian cyclic group. Every Γ=Zn of order n⩽12 is considered. This results in 60 chiral models, and a systematic analysis with n<8 yields four containing the minimal SUSY standard model with three families. One of these models extends to an infinite sequence of three-family MSSMs. We also give a lower bound on the number of chiral models for all values of n.
