Connection between proton decay suppression and seesaw mechanism in supersymmetric SO(10) models

TL;DR

This paper presents a mechanism linking proton decay suppression to the seesaw mechanism in supersymmetric SO(10) models, connecting proton lifetime with intermediate vacuum expectation values.

Contribution

It introduces a novel suppression mechanism for proton decay in supersymmetric SO(10) models tied to the seesaw mechanism and intermediate vacuum expectation values.

Findings

Proton decay can be effectively suppressed in the model.

Proton lifetime is directly related to the seesaw-related vacuum expectation value.

Model aligns with minimal supersymmetric standard model components.

Abstract

We propose a mechanism to suppress proton decay induced by dimension-5 operators in a supersymmetric SO(10) model. Proton lifetime is directly connected with the intermediate vacuum expectation value which is responsible for the seesaw mechanism. The model shows many consistencies with the present theoretical results such as the components of the two Higgs doublets in the minimal supersymmetric standard model.
