Abstract

Decays of scalar mesons \(K^*_0(800) \rightarrow K\pi \) and \(K^*_0(1430) \rightarrow K\pi , K \eta , K \eta ', K_1 \pi \) are described in the extended \(U(3 ) \times U(3)\) Nambu–Jona–Lasinio chiral quark model. The obtained results are in satisfactory agreement with the new experimental data obtained by the BaBar collaboration, which markedly differ from the existing values in the PDG.
