Query: Determination of the compositeness of resonances from decays: the case
  of the $B^0_s\to J/\psi f_1(1285)$   We develop a method to measure the amount of compositeness of a resonance,
mostly made as a bound state of two hadrons, by simultaneously measuring the
rate of production of the resonance and the mass distribution of the two
hadrons close to threshold. By using different methods of analysis we conclude
that the method allows one to extract the value of 1-Z with about $0.1$ of
uncertainty. The method is applied to the case of the $\bar B^0_s \to J/\psi
f_1(1285)$ decay, by looking at the resonance production and the mass
distribution of $K \bar K^*$.
