Two-Photon Decay Rates of True Neutral Pseudoscalar Mesons from Data on their Transition Form Factors
arXiv:1009.1222
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.
