On the decay widths of radially excited scalar meson $K_{0}^{*} (1430)$ in view of new experimental data

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

Decays of scalar mesons $K_{0}^{*} (800) \to K π$ and $K_{0}^{*} (1430) \to K π, K η, K η^{'}, K_{1} π$ are described in the extended $U (3) \times U (3)$ Nambu - Jona-Lasinio chiral quark model. Th…

The decay $η^{'} \to π ρ$ in the chiral NJL model

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

The branching fraction of the decay $η^{'} \to π ρ$ is calculated in the chiral quark NJL model. The decay exists due to the mass difference between $u$ - and $d$ -quarks leading to $π^{…

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…
