Decays $τ \to 3 K ν_{τ}$ in $U (3) \times U (3)$ quark NJL model

M. K. Volkov, A. A. Pivovarov, K. Nurlan

The widths of the decays $τ \to K^{-} K^{+} K^{-} ν_{τ}$ and $τ \to K^{-} K^{0} K ˉ^{0} ν_{τ}$ are calculated in the $U (3) \times U (3)$ chiral quark NJL model. Four channels are considered: conta…

The decay $τ \to 3 π ν_{τ}$ and axial-vector meson $a_{1}$ in the NJL model

Volkov M. K., Nurlan K., Pivovarov A. A

The branching fractions of $τ \to π^{+} π^{-} π^{-} ν_{τ}$ and $τ \to π^{-} 2 π^{0} ν_{τ}$ are calculated within the chiral NJL model. Features of the axial-vector $a_{1}$ meson which plays an importan…

Low-energy interactions of mesons with participation of the first radially excited states in $U (3) \times U (3)$ NJL model

M. K. Volkov, A. A. Pivovarov, K. Nurlan

The $U (3) \times U (3)$ chiral symmetric NJL model describing pseudoscalar, vector, and axial vector mesons in both the ground state and first radially excited states is shortly pre…
