Decays of radially excited vector mesons $ρ^{'}$ and $ω^{'}$ in the extended NJL model

M. K. Volkov, A. B. Arbuzov, A. A. Pivovarov +1

The decay widths of $ρ^{'} \to π π, ω π, ρ η$ , $ω^{'} \to ρ π, ω η$ and $π^{'} \to ρ π$ are recalculated within the extended NJL quark model. It is shown that the mass of $ρ^{'} (1450)$ meson in the…
