Estimates for parameters and characteristics of the confining SU(3)-gluonic field in an ${\eta }^{\prime }$-meson

Abstract

The confinement mechanism proposed earlier by the author is applied to estimate the possible parameters of the confining SU(3)-gluonic field in an ${\eta }^{\prime }$-meson. For this aim the electric form factor of an ${\eta }^{\prime }$-meson is nonperturbatively computed in an explicit analytic form. The estimates obtained are also consistent with the width of the electromagnetic decay ${\eta }^{\prime }\to 2\gamma$. The corresponding estimates of the gluon concentrations, electric and magnetic colour field strengths are also adduced for the mentioned field at the scales of the meson under consideration.
