We study the rare B meson decays B±,0→J/ψK+K-K±,0, B±,0→J/ψφK±,0, and search for B0→J/ψφ, using 469×106 BB¯ events collected at the γ(4S) resonance with the BABAR detector at the PEP-II e+e- asymmetric energy collider. We present new measurements of branching fractions and a study of the J/ψφ mass distribution in search of new charmonium-like states. In addition, we search for the decay B0→J/ψφ and find no evidence of a signal.
