The study of B decays into states containing a meson with quark content and a J/ψ meson was discussed. The Cabibbo-Kobayashi-Maskawa model was proved by the CP violating B meson decays into CP eigenstates with charmonium. The branching fractions were measured and the the upper limits were set at 90% confidence level.
