Radiative decays of vector mesons in the gauge model of quark-meson interactions

TL;DR

This paper models meson radiative decays using an extended gauge symmetry framework, providing theoretical predictions that align well with experimental data.

Contribution

It introduces a gauge model based on extended symmetry to describe meson radiative decays, integrating quark-meson interactions within a linear sigma-model.

Findings

The model's predictions agree with experimental data for certain vector meson decays.

The approach extends traditional sigma-models with gauge interactions.

Parameters of the model are discussed and constrained by data.

Abstract

We consider meson radiative decays within the framework of $U_0(1)\times U(1)\times SU(2)$ gauge symmetry. This approach is based on the linear sigma-model extended by the gauge and quark-meson interactions. Physical content and parameters of the model are discussed. Theoretical predictions for some radiative decays of vector mesons are in a good agreement with the experimental data.
