Ying-Kang Chen, Da-Xin Zhang
TL;DR
This paper presents a renormalizable supersymmetric SO(10) grand unified model that naturally addresses key challenges like the seesaw mechanism, doublet-triplet splitting, and proton decay suppression by introducing an extra discrete symmetry.
Contribution
The authors construct a novel supersymmetric SO(10) model that overcomes longstanding issues in grand unified theories through the use of an additional discrete symmetry.
Findings
Model successfully incorporates the seesaw mechanism without disrupting gauge coupling unification.
Natural resolution of doublet-triplet splitting problem.
Effective suppression of proton decay in the model.
Abstract
A realistic grand unified model has never been constructed in the literature due to three major difficulties: the seesaw mechanism without spoiling gauge coupling unification, the doublet-triplet splitting and the proton decay suppression. We propose a renormalizable supersymmetric SO(10) model with all these difficulties solved naturally by imposing an extra discrete symmetry.
