Two-Photon Decay Rates of True Neutral Pseudoscalar Mesons from Data on their Transition Form Factors

Abstract

By means of the universal unitary and analytic model of electromagnetic structure of hadrons the two-photon decay rates of P=pi^0, eta, eta' mesons are determined in an alternative way from data on their transition form factors.
