TL;DR
This paper introduces a renormalizable supersymmetric SO(10) model that addresses the doublet-triplet splitting problem via the Dimopoulos-Wilczek mechanism and discusses proton decay suppression strategies.
Contribution
It presents a novel SO(10) model with a filter sector to prevent unwanted couplings, advancing solutions to the doublet-triplet splitting issue in supersymmetric GUTs.
Findings
Successful implementation of the Dimopoulos-Wilczek mechanism
Proposed a filter sector to forbid unwanted couplings
Identified challenges in suppressing proton decay
Abstract
We propose a renormalizable supersymmetric SO(10) model where the doublet-triplet splitting problem is solved using the Dimopoulos-Wilczek mechanism. An unwanted coupling is forbidden through a filter sector. To suppress proton decay without spoiling gauge coupling unification, there is a problem in the weak doublets which requires further improvements.
