Proton Decay and Fermion Masses in Supersymmetric SO(10) Model with Unified Higgs Sector

TL;DR

This paper analyzes proton decay constraints and fermion mass generation in a supersymmetric SO(10) model, demonstrating compatibility with experimental bounds and predicting significant CKM unitarity violations.

Contribution

It introduces quark mixing into the model and shows it can produce realistic fermion masses without conflicting with proton decay limits.

Findings

Model can generate fermion masses within experimental bounds

Predicts large CKM unitarity violations

Proton decay constraints are satisfied

Abstract

We make a detailed analysis on the proton decay in a supersymmetric SO(10) model proposed by K.Babu, I.Gogoladze, P.Nath, and R. Syed. We introduce quark mixing, and find that this model can generate fermion mass without breaking the experimental bound on proton decay. We also predict large CKM unitarity violations.
