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

We present an analysis of compactifications of the type PiB superstring on AdS(5) x S-5/Gamma where Gamma is an Abelian cyclic group. Every Gamma = Z(n) of order n less than or equal to 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. (C) 2001 Published by Elsevier Science B.V.
