Abstract
Tau-lepton semileptonic decays are described in the Nambu–Jona-Lasinio framework, and the validity of this description is discussed. Tau decays with a neutrino, a vector meson, and a pseudoscalar meson in the final state are considered. The extended version of the NJL model is employed, which makes possible the consideration of the contributions of both the ground and first radially excited meson states.
