Comment on "Radiative decays, nonet symmetry and SU(3) breaking" by M. Benayoun et al

TL;DR

This paper critiques a previous model of meson decays, demonstrating that it incorrectly predicts the absence of the  decay process due to nonet symmetry and SU(3) breaking assumptions.

Contribution

It provides a critical analysis showing the  decay is not predicted by the model proposed in the referenced paper.

Findings

The decay  is absent in the model.

The model's assumptions about nonet symmetry and SU(3) breaking are challenged.

The critique clarifies the limitations of the original model.

Abstract

We comment on the paper by Benayoun, DelBuono, Eidelman, Ivanchenko, and O'Connell [Phys. Rev. {\bf D 59}, 114027 (1999)]. We show that the decay $\phi\to\pi^0\gamma$ is absent in model of the nonet symmetry and SU(3) breaking suggested by authors.
