Abstract

Based on previous studies that support the vector-vector molecular structure of the f₂(1270), f'₂(1525), K^{* 0}₂(1430), f₀(1370) and f₀(1710) resonances, we make predictions for ψ(2S) decay into ω(ϕ) f₂(1270), ω(ϕ) f'₂(1525), K^*0(892) K^{* 0}₂(1430) and radiative decay of Υ(1S),Υ(2S), ψ(2S) into γf₂(1270), γf'₂(1525), γf₀(1370), γf₀(1710). Agreement with experimental data is found for three available ratios, without using free parameters, and predictions are done for other cases.
