$B ˉ^{0}$ and $B ˉ_{s}^{0}$ decays into $J / ψ$ and $f_{0} (1370), f_{0} (1710), f_{2} (1270), f_{2}^{'} (1525), K_{2}^{*} (1430)$

We make predictions for the ratios of branching fractions of $B ˉ^{0}$ and $B ˉ_{s}^{0}$ decays into $J / ψ$ and the scalar mesons $f_{0} (1370), f_{0} (1710)$ or tensor mesons $f_{2} (1270), f_{2}^{'} (1525), K_{2}^{*} (1430)$ . The theoretical approach is based on results of chiral unitary theory where these resonances are shown to be generated from the vector meson-vector meson interaction. Eight independent ratios can be predicted and comparison is made with the recent data on $B ˉ_{s}^{0}$ decay into $J / ψ f_{2}^{'} (1525)$ versus the $B ˉ_{s}^{0}$ decay into $J / ψ f_{2} (1270)$ .
