Abstract

We study the rare B meson decays B^(±,0)→J/ψK^+K^−K^(±,0), B^(±,0) → J/ψϕK^(±,0), and search for B^0→J/ψϕ, using 469×10^6 BB¯ events collected at the Υ(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 B^0 → J/ψϕ and find no evidence of a signal.
