Study of the J / ψ → ϕ (ω) f2 (1270), J / ψ → ϕ (ω) f2′ (1525) and J / ψ → K* 0 (892) over(K, ̄)2* 0 (1430) decays

We present an approach to study the decay modes of the J / ψ into a vector meson and a tensor meson, taking into account the nature of the f₂ (1270), f₂^′ (1525), over(K, ̄)₂^{* 0} (1430) resonances as dynamically generated states from the vector meson-vector meson interaction. We evaluate four ratios of partial decay widths in terms of a flavor dependent OZI breaking parameter and the results obtained compare favorably with experiment, although the experimental uncertainties are still large. Further refinements of the data would provide a more stringent test on the theoretical approach. The fit to the data is possible due to the particular strength and sign of the couplings of the resonances to pairs of vector mesons given by the theory.
