Comment on "Standard Model Mass Spectrum and Interactions In The Holomorphic Unified Field Theory"

TL;DR

This paper critiques a proposed unified theory of gravity and the Standard Model, highlighting a photon mass prediction, gauge invariance issues, and potential domain wall problems, thus questioning its consistency and completeness.

Contribution

It identifies an overlooked photon mass prediction and discusses gauge invariance and domain wall issues in the proposed unification model.

Findings

Photon acquires a mass at one loop due to gauge invariance issues.

The model has potential domain wall problems.

Clarifies misconceptions about Wick rotation in the context of the theory.

Abstract

In arXiv:2508.02747 a theory that unifies gravity and the Standard Model was proposed. It is finite, unitary, and accurately predicts all parameters of the Standard Model in terms of only two input parameters. Here I point out one prediction that was overlooked, namely that the photon acquires a mass at one loop due to the lack of gauge invariance in the nonlocal interaction vertices of the proposed model. In a second iteration, a red herring concerning Wick rotation is clarified, and the difficulties relating to gauge invariance in the theory are further spelled out. I point out that their model apparently has a domain wall problem.
