Violation of Quantum Gauge Invariance in Georgi-Glashow SU(5)
Martin Ambauen, Gunter Scharf
TL;DR
This paper investigates whether the Georgi-Glashow SU(5) grand unified model maintains quantum gauge invariance at perturbative levels and finds it does not meet the necessary invariance conditions.
Contribution
It provides a first and second order perturbative analysis showing the SU(5) model violates quantum gauge invariance.
Findings
SU(5) model fails gauge invariance at second order
Perturbative analysis reveals incompatibility with quantum gauge invariance
Results challenge the consistency of the SU(5) grand unified theory
Abstract
We check whether the SU(5) model, originally suggested by Georgi and Glashow, is compatible with perturbative quantum gauge invariance in first and second order for massive asymptotic gauge fields. We see that this is not the case: the SU(5) grand unified model does not meet with our restrictions from second order gauge invariance.
