“…To determine the masses of the constituent quarks and the ultraviolet cut-off parameter Λ 4 of the quark loops, two equations will be used from the experimental values of the decay widths π → µν (F π = 92.4 MeV) and the strong decay ρ → ππ (g ρ = 6.0) [28].…”

“…The correction of the same level can be achieved by variation of the width of the intermediate radially excited meson within the experimental errors. When describing a similar process e + e − → K + K − in the extended NJL model [50], a satisfactory result was obtained without taking into account the interactions in the final state. All these facts indicate the decreasing role of the interactions in the final state, while the role of excited mesons in the intermediate state increases.…”

The U (3) × U (3) chiral symmetric NJL model describing pseudoscalar, vector, and axial vector mesons in both the ground state and first radially excited states is shortly presented in this review. In this model, it is possible to describe a large number of low-energy interactions of mesons, τ lepton decays into mesons and processes of meson production in electron-positron annihilations in satisfactory agreement with the experiments. In describing a number of processes, it turned out to be necessary to take into account the interactions of mesons in the final state.

The Nambu–Jona-Lasinio model is applied to describe processes of electron-positron annihilation into mesons at center-of-mass energies below 2GeV and hadronic decays of tau leptons. Contributions of intermediate scalar, vector, and axial-vector mesons in the ground and first radial excited states are taken into account. Comparisons with existing experimental data are performed. Theoretical predictions for several(not yet measured)processes are presented.
