Three family Nu=1 SUSY models from Z(n) 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 ch iral models, and a systematic analysis with n < 8 yields four containing th e minimal SUSY standard model with three families. One of these models exte nds to an infinite sequence of three-family MSSMs. We also give a lower bou nd on the number of chiral models for all values of n. (C) 2001 Published b y Elsevier Science B.V.
