Disconnected Quark Diagram in Decays of
K. Ninomiya · Progress of Theoretical Physics · 1976
Based on the quartet model, three body decays ψ(ψ′) →VPP and ρ′ →ρππ are analysed. It is shown that the decay widths can be explained by taking into consideration of the disconnected quark diagram whose coupling have SU(3) and SU(4) breaking pattern like in Pomeron exchange processes.
