Modified Pati-Salam Model from $Z_7$ orbifolded AdS/CFT

TL;DR

This paper constructs a modified Pati-Salam model derived from $Z_7$ orbifold compactifications of type IIB superstring theory, which reduces to the Standard Model after symmetry breaking.

Contribution

It introduces a novel three-family non-supersymmetric model based on $Z_7$ orbifolding that connects string theory compactifications to the Standard Model.

Findings

Identifies a consistent $Z_7$ orbifold model with three families.

Demonstrates reduction to the Standard Model after symmetry breaking.

Provides a string-inspired framework for particle physics model building.

Abstract

We consider models built on $AdS_5\otimes S^5/\Gamma$ orbifold compactifications of the type $IIB$ superstring, where $\Gamma$ is the abelian group $Z_n$. An attractive three family $\mathcal{N}=0$ SUSY model is found for $n=7$ that is a modified Pati--Salam Model which reduced to the Standard Model after symmetry breaking.
