Decay widths of radially excited vector mesons of the $U (3)$ nonet with production of three pseudoscalar mesons in the extended NJL model

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

In the extended NJL model, the decays of the first radially excited vector mesons $ρ^{'}$ , $ω^{'}$ , $ϕ^{'}$ and $K^{*}^{'}$ with production of $3 P$ , where $P = K, π, η$ are calculated. The box chan…
