Description
The LHCb dataset provides the potential to significantly improve the knowledge of $B^0_{(s)} \to J/\psi K_S^0 h^+ h^{(\prime)-}$ decays. Exotic charmonia states have been observed (or claimed), produced in B decays together with a kaon, and decaying to $J/\psi h^+ h^{(\prime)-}$: the $X(3872)$ decaying to $J/\psi \pi^{+} \pi^{-}$, and the $X(4140)$ decaying to $J/\psi \phi$. These could be searched for in the $JJ/\psi K_S^0 h^+ h^{(\prime)-}$ final states. We present progress towards measurements of the relative branching fractions and studies of the composition of $B^0_{(s)} \to J/\psi K_S^0 h^+ h^{(\prime)-}$ decays.
