Description
The extended Nambu–Jona-Lasinio model is briefly described and various ways of its application are demonstrated. Theoretical treatment of low-energy meson production processes in colliding e+e- beams and tau lepton decays is reviewed. The processes considered occur via intermediate scalar, vector, and axial-vector mesons in the ground state and in the first radial excited one. The model employed uses the concept of spontaneous chiral symmetry breaking to describe such states. Experimental and theoretical comparisons with other phenomenological strong interaction models are presented. The talk is based on the review [M.K. Volkov, A.B. Arbuzov, Phys. Usp. 60 (2017) 643] and a few later articles.
