Decays *t*>3K*n&sub(*t) in the U(3) x U(3) Quark NJL Model / M.K.Volkov, A.A.Pivovarov, K.Nurlan // The European Physical Journal A [Electronic resource]. – 2023. – Vol.59, No.7. – P.175. – URL: https://doi.org/10.1140/epja/s10050-023-01065-w. – Bibliogr.:24.

The widths of the decays τ→K−K+K−ντ and τ→K−K0K¯0ντ are calculated in the U(3)×U(3) chiral quark NJL model. Four channels are considered: contact, axial vector, vector, and pseudoscalar channels. It is shown that the dominant contribution is given by the axial vector channel with an intermediate ϕ meson. The results obtained are in satisfactory agreement with the experimental data.
