Abstract

A general expression for the two-photon form factor of neutral pseudoscalar mesons is given in a quark triangle model. Various electromagnetic decay amplitudes are calculated, including Dalitz pair decays and the rare decay into a lepton pair, where an old calculation in a similar (nucleon loop) model is corrected. The results are in agreement with other calculations based on vector meson dominance, giving a new example of Q2 duality. Some remarks concerning the soft limit in the processes are given. © 1983.
