DESCRIPTION:Speakers: Andrej Arbuzov (Joint Institute for Nuckear Research
 )\nThe extended Nambu–Jona-Lasinio model is briefly described and variou
 s ways of its application are demonstrated. Theoretical treatment of low-e
 nergy meson production processes in colliding e+e- beams and tau lepton de
 cays is reviewed. The processes considered occur via intermediate scalar\,
  vector\, and axial-vector mesons in the ground state and in the first rad
 ial excited one. The model employed uses the concept of spontaneous chiral
  symmetry breaking to describe such states. Experimental and theoretical c
 omparisons with other phenomenological strong interaction models are prese
 nted. The talk is based on the review [M.K. Volkov\, A.B. Arbuzov\, Phys. 
 Usp. 60 (2017) 643] and a few later articles.\n\nhttps://indico.inp.nsk.su
