Three-Meson *t Decays Involving Kaons and *h Mesons in the NJL Model / M.K.Volkov, A.A.Pivovarov, K.Nurlan // Physical Review D [Electronic resource]. – 2024. – Vol. 109, No. 1. – P. 016016. – URL: https://doi.org/10.1103/PhysRevD.109.016016. – Bibliogr.: 37.

Branching fractions of decays τ→K*0π*-ην&sub(τ), τ→K*-π*0ην&sub(τ), τ→K*-K*0ην&sub(τ), and τ→K*-ηην&sub(τ) are calculated in the U(3) × U(3) chiral Nambu–Jona-Lasinio quark model. The contact, vector, axial-vector, and pseudoscalar channels are considered. It is shown that the axial vector channel is dominant. The obtained results are in satisfactory agreement with experiment.
