Examining A Renormalizable Supersymmetric SO(10) Model

TL;DR

This paper investigates a renormalizable supersymmetric SO(10) grand unified model, demonstrating its construction, proton decay predictions, and compatibility with experimental data, highlighting issues when extending the Yukawa sector.

Contribution

It presents a detailed analysis of a minimal renormalizable SUSY SO(10) model, including its construction and phenomenological implications, and explores the effects of adding an extra Higgs representation.

Findings

Model successfully predicts proton decay rates consistent with experiments.

Minimal Yukawa couplings align with observed data.

Adding $120_H$ introduces inconsistencies with experimental constraints.

Abstract

We examine a renormalizable SUSY SO(10) model without fine-tuning. We show how to construct MSSM doublets and to predict proton decay. We find that in the minimal set of Yukawa couplings the model is consistent with the experiments, while including $120_H$ to fit the data there are inconsistencies.
