The Decay *t*>3*p*n&sub(*t) and Axial-Vector Meson a&sub(1) in the NJL Model / M.K.Volkov, K.Nurlan, A.A.Pivovarov // Modern Physics Letters A [Electronic resource]. – 2023. – Vol. 38, No. 22/23. – P. 2350110. – URL: https://doi.org/10.1142/S0217732323501109. – Bibliogr.: 31.

The branching fractions of τ→π*+π*-π*-ν&sub(*t) and τ→π−2π*0ν&sub(*t) are calculated within the chiral NJL model. Features of the axial-vector a1 meson which play an important role in describing the τ decays are discussed. Permissible values for the mass and width of the a1 meson are considered in accordance with the latest experiments.
