Description

On the basis of the confinement mechanism earlier proposed by author the electric formfactor of π0-meson is nonperturbatively calculated. The latter is then applied to describing electromagnetic decays π0→2γ and π0→e+e-γ which entails estimates for parameters of the confining SU(3)-gluonic field in π0-meson. The corresponding estimates of the gluon concentrations, electric and magnetic colour field strengths are also adduced for the mentioned field
