Vector-Meson-Dominance model contribution to ${\pi }^0\to 4\gamma$

Abstract

Vector-Meson-Dominance model contribution to ${\pi }^0\to 4\gamma$ is calculated. The result confirms old estimates that this contribution is much smaller than the purely electromagnetic photon spliting graph contribution calculated earlier.
