Leptonic color models from Z_8 orbifolded AdS/CFT

TL;DR

This paper explores orbifold compactifications of type IIB superstring theory on AdS_5 x S^5/Z_8, constructing non-supersymmetric models with three or four families based on quartification, aiming to connect string theory with standard model features.

Contribution

It introduces specific Z_8 orbifold models that produce non-SUSY three and four family theories with leptonic color sectors, advancing string phenomenology.

Findings

Constructed two distinct quartification models from Z_8 orbifolds.

Demonstrated reduction to the standard model with leptonic color.

Provided frameworks for non-SUSY string-derived particle models.

Abstract

We study orbifold compactifications of the type IIB superstring on AdS_5 x S^5/Gamma, where Gamma is the abelian group Z_8, which can lead to non-SUSY three and four family models based on quartification. In particular, we focus on two models, one fully quartified model and one a model with two trinification families and one quartification family, which reduces to the standard model with a minimal leptonic color sector.
