| Popis: | On the basis of the confinement mechanism earlier proposed by author the electric formfactor of π 0 -meson is nonperturbatively calculated. The latter is then applied to describing electromagnetic decays π 0 → 2 γ and π 0 → e + e − γ which entails estimates for parameters of the confining SU ( 3 ) -gluonic field in π 0 -meson. The corresponding estimates of the gluon concentrations, electric and magnetic colour field strengths are also adduced for the mentioned field. |
