Description
A Lagrangian formulation of the Nambu-Jona-Lasinio model with separable interaction is proposed. Electromagnetic interaction is introduced into the nonlocal quark current in a nonminimal way. The pion weak decay constant, the two-photon decay width, as well as the form factor of the γ*π0 → γ transition and the pion charge form factor, are calculated. Two free parameters, namely, the range parameter Λ appearing in the separable interaction and the constituent quark mass mq, are fixed by fitting the experimental data for pion decay constants. 17 refs., 6 figs., 3 tabs
