Seminar topic: “On the decay widths of radially excited scalar meson K*0(1430) in view of new experimental data”

Speaker: Kanat Nurlan

Abstract:

Decays of scalar mesons K*0(800) → Kπ and K*0(1430) → Kπ, Kη, Kη‘, K1π are described in the extended U(3) × 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.
