TL;DR

This paper discusses the minimal non-supersymmetric SO(10) grand unified model, highlighting its predictive power and potential for experimental verification through proton decay and collider-accessible exotics.

Contribution

It demonstrates the robustness of gauge unification in this model, enabling precise proton lifetime estimates and identifying testable light-scale exotics.

Findings

Gauge unification pattern is robust against Planck-scale effects

Proton lifetime can be estimated with better than leading order precision

Light-scale exotics may be accessible at future colliders

Abstract

We comment on the status and prospects of the minimal non-supersymmetric renormalizable SO(10) grand unified model. We emphasize its unique predictive power owing to the particular robustness of the gauge unification pattern to the leading-order Planck-scale effects which, in turn, makes it essentially the only unified framework in which the proton lifetime may be estimated with better than the leading order precision. This, together with the frequent presence of light-scale exotics accessible, in principle, at future colliders, is the key to its potential testability at the upcoming megaton-scale facilities such as Hyper-Kamiokande or LENA.
