Modified Pati-Salam Model from orbifolded AdS/CFT
We consider models built on orbifold
compactifications of the type superstring, where is the abelian
group . An attractive three family SUSY model is found for
that is a modified Pati--Salam Model which reduced to the Standard Model
after symmetry breaking.Comment: 8 pages, 1 figure, Phenomenology section revised to correct

Three Family N=1 SUSY Models from Z_n Orbifolded AdS/CFT
We present an analysis of compactifications of the type IIB superstring on
AdS_5 x S^5 / \Gamma, where \Gamma is an abelian cyclic group. Every \Gamma
=Z_n 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.Comment: 7 pages RevTeX, version to be published in Phys. Lett.
MSSM from Ads/CFT
We develop a robust version of the MSSM from a orbifolded AdS/CFT,
with natural low scale unification and briefly discuss cosmology in this
testable model.Comment: 12 pages latex and one eps figur
Proton Decay Constraints on Low Scale AdS/CFT Unification
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 SUSY, and strongly
constrains non-SUSY, low scale trinification type unification of
orbifolded AdS models.Comment: 10 page
