Study of B{+-,0} --> J/ψ K+ K- K{+-,0} and search for B0 --> J/ψ ϕ at BABAR

We study the rare B meson decays B{+-,0} --> J/ψ K^+ K^- K{+-,0}, B{+-,0} --> J/ψ ϕ K{+-,0}, and search for B0 --> J/ψ ϕ, using 469 million BBbar events collected at the Upsilon(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/ψϕmass distribution in search of new charmonium-like states. In addition, we search for the decay B0 --> J/ψ ϕ, and find no evidence of a signal.
