Estimates for parameters and characteristics of the confining SU(3)-gluonic field in $\eta$-meson from two-photon decay

TL;DR

This paper nonperturbatively calculates the electric form factor of the eta-meson based on a confinement mechanism, then uses it to estimate parameters of the confining SU(3)-gluonic field from its two-photon decay.

Contribution

It introduces a nonperturbative calculation of the eta-meson's electric form factor and derives parameters of the confining SU(3)-gluonic field from decay data.

Findings

Estimates of gluon concentrations in the eta-meson

Electric and magnetic color field strengths in the confining field

Parameters of the SU(3)-gluonic field derived from decay data

Abstract

On the basis of the confinement mechanism earlier proposed by author, the electric form factor of $\eta$-meson is nonperturbatively calculated. The latter is then applied to describe electromagnetic decay $\eta\to2\gamma$ which entails estimates for parameters of the confining SU(3)-gluonic field in $\eta$-meson. The corresponding estimates of the gluon concentrations, electric and magnetic colour field strengths are also adduced for the mentioned field.
