TL;DR

This paper investigates embedding supersymmetric GUT textures into superstring models, constructing SO(10) models with specific features like adjoint scalars, three generations, and targeted Yukawa couplings.

Contribution

It presents the construction of SO(10) superstring models with adjoint scalars and realistic fermion content, advancing string-based GUT model building.

Findings

Successfully constructed SO(10) models with adjoint scalars.

Models include three generations of chiral fermions.

Yukawa couplings are restricted to the third generation.

Abstract

We explore the possibility of embedding supersymmetric GUT texture ideas into superstring models. We discuss the construction of GUT models using free fermionic strings. We find SO(10) models with adjoint scalars, three generations of chiral fermions, and a fundamental Higgs with a Yukawa coupling to only the third generation.
