τ Lepton Decays with Production of Strange Scalar Mesons $K_{0}^{*}$(700) and $K_{0}^{*}$(1430) in the Extended NJL Model

The branching fractions of τ lepton decays with the production of strange scalar mesons both in the ground and first radially excited states τ^– → ν_τ[$K_{0}^{*}$(700)^–, $K_{0}^{*}$(1430)^–] and τ^– → ν_τ[$K_{0}^{*}$(700)^–π⁰, $K_{0}^{*}$(1430)^–π⁰, $K_{0}^{*}$(700)^–K⁰, $K_{0}^{*}$(700)^–η] are calculated in the extended U(3) × U(3) chiral quark Nambu–Jona-Lasinio model. All mesons are considered as $q\bar {q}$ systems. The obtained results should be considered as predictions for future experiments.
