讨论了强子衰变过程 J/ψ→ωπ~+π~-包含的三个不同中间过程 J/ψ→ωf_2(1270),f_2→π~+π~-和 J/ψ→b_1~±(1235)π~,b_1~±→ωπ~±的耦合问题.这种耦合效应的考虑对于精确测定共振态 f_2和 b_1~±的参数以及这些反应道的螺旋度振幅比是十分重要的.
Three different intermediate processes J / ψ → ωf_2 (1270), f_2 → π ~ + π ~ - and J / ψ → b_1 ~ ± (1235) contained in the hadronic decay process J / ψ → ωπ ~ + π ~ ) π ~, b_1 ~ ± → ωπ ~ ± The coupling effect is very important for accurately determining the parameters of the resonance states f_2 and b_1 ~ ± and the helicity amplitude ratio of these channels.
