Abstract
The decay of E/ι -meson ( I G = 0 + , J PC = 0 −+ ) through the chain E/ι → K*K̄ ( K̄*K ) → KK̄π is studied in the framework of the model containing pole and triangle diagrams. The region with total mass (energy) of the ( E/ι ) M ∼ 1400 ÷ 1500 MeV is considered. The final state KK̄ -rescattering through a o (980)-meson is taken into account in the triangle diagram. The contribution of a o π -mode from triangle diagram is shown to be small and consistent with the existing experimental data.
