Query: $\phi\phi$ and $J/\psi\phi$ mass spectra in decay $B^0_s\to
  J/\psi\phi\phi$   The mass spectra of the $\phi\phi$ and $J/\psi\phi$ states in the decay
$B^0_s\to J/\psi\phi\phi$ recently observed by LHCb are calculated in the model
which takes into account the $J^P=0^+,0^-,2^+$ intermediate resonances $R_1$,
$R_2$ in the $\phi\phi$ channel and the $J^P=1^+$ ones, $X_1$, $X_2$, in the
$J/\psi\phi$ channel. When obtaining the expressions for the effective
amplitudes and mass spectra, the approximate threshold kinematics of the decay
is used essentially. The $R_1-R_2$ and $X_1-X_2$ mixings arising due to the
common decay modes $\phi\phi$ and $J/\psi\phi$, respectively, are also taken
into account. The obtained expressions for the mass spectra are applied for
extracting the information about masses and coupling constants of the
resonances in the $\phi\phi$ and $J/\psi\phi$ final states.
