- LHCb data on $B^0\to\jpsi π^+π^-$, $B_{s} ^0\to\jpsi π^+π^-$ and $B_{s} ^0\to\jpsi K^+K^-$ are fitted in a coupled-channel analysis jointly with data on radiative $\jpsi$ decays, $ππ$ elastic scattering and further data sets. Branching ratios for $B_{(s)} ^0\to\jpsi f_0,f_2$ are determined and compared to branching ratios from radiative $J/ψ$ decays. Above 1500\,MeV, only little intensity is observed in $B_{(s)} ^0\to\jpsi f_0,f_2$ decays while in radiative $\jpsi$ decays the intensities peak at 1865\,MeV in the scalar, and at 2210\,MeV in the tensor wave. This pattern is interpreted as further support for the glueball interpretation of $G_0(1865)$ and $G_2(2210)$.
