A Missing Partner Model With 24-plet Breaking SU(5)
Da-Xin Zhang, Jun-hui Zheng
TL;DR
This paper proposes a missing partner grand unified model using a 24-plet to break SU(5), achieving fermion mass generation, extended perturbative unification, and proton decay constraints at a high-energy renormalizable level.
Contribution
It introduces a novel missing partner model with a 24-plet for SU(5) breaking, differing from traditional 75-plet approaches, and ensures compatibility with fermion masses and proton decay limits.
Findings
Successful SU(5) breaking with 24-plet
Extended perturbative unification region
Proton decay constraints satisfied
Abstract
We give a missing partner model using 24-plet instead of 75-plet to break the SU(5) symmetry. Fermion masses and mixing are generated through the Georgi-Jarlskog mechanism. The model is constructed at renormalizable level at very high energy. The perturbative region is extended for the unification gauge coupling. Constrains by proton decay is also satisfied.
