Decays of radially excited vector mesons ρ′ and ω′ in the extended NJL model
The decay widths of , and are recalculated within the extended Nambu–Jona-Lasinio (NJL) quark model. It is shown that the mass of meson derived in the NJL model agrees with the one given in Particle Data Group tables but significantly deviates from the recent result of CMD-3 collaboration. Comparisons with earlier theoretical results are presented.
