Dynamical selection rule in the decays of π(1800)

Combined analysis of π(1800) decays is performed using results of the VES experiment on its decays into f0(980)π, f0(1500)π, f0(600 ÷ 1300)π, κK, a0(ηπ)π, ηη′π, ρπ and K*K channels. Relative branching ratios of those decay modes are measured. It is shown that the OZI selection rule is strongly violated in π(1800) decays. Observed pattern of π(1800) decays can be explained in terms of assumption, that π(1800) decay proceeds via SU(3)‐singlet and SU(3)‐octet states.
