Estimates for parameters and characteristics of the confining SU(3)-gluonic field in \pi^0-meson from one- and two-photon decays

Abstract

On the basis of the confinement mechanism earlier proposed by author the electric formfactor of ${\pi }^0$-meson is nonperturbatively calculated. The latter is then applied to describing electromagnetic decays ${\pi }^0\to 2\gamma$ and ${\pi }^0\to e^{+}{e}^{-}\gamma$ which entails estimates for parameters of the confining SU(3)-gluonic field in ${\pi }^0$-meson. The corresponding estimates of the gluon concentrations, electric and magnetic colour field strengths are also adduced for the mentioned field.
