Study of the $f_{2} (1270)$ , $f_{2}^{'} (1525)$ , $K ˉ_{2}^{*} (1430)$ , $f_{0} (1370)$ and $f_{0} (1710)$ production from $ψ (n S)$ and $Υ (n S)$ decays

Based on previous studies that support the important role of the $f_{2} (1270)$ , $f_{2}^{'} (1525)$ , and $K ˉ_{2}^{*} (1430)$ resonances in the $J / ψ [ψ (2 S)] \to ϕ (ω) V V$ decays, we make an analysis of the analogous decays of $Υ (1 S)$ and $Υ (2 S)$ , taking into account recent experimental data. In addition, we study the $J / ψ$ and $ψ (2 S)$ radiative decays and we also made predictions for the radiative decay of $Υ (1 S)$ and $Υ (2 S)$ into $γ f_{2} (1270)$ , $γ f_{2}^{'} (1525)$ , $γ f_{0} (1370)$ and $γ f_{0} (1710)$ , comparing with the recent results of a CLEO experiment. We can compare our results for ratios of decay rates with eight experimental ratios and find agreement in all but one case, where experimental problems are discussed.
