Abstract

The branching fractions of τ lepton decays with the production of strange scalar mesons both in the ground and first radially excited states @ and @ 
 are calculated in the extended @ chiral quark Nambu–Jona-Lasinio model. All mesons are considered as @ systems. The obtained results should be considered as predictions for future experiments.
