Abstract

We study the rare B meson decays B ;0 → J=ψKþK−K ;0, B ;0 → J=ψϕK ;0, and search for B0 → J=ψϕ, using 469 × 106 BB¯ events collected at the ϒð4SÞ resonance with the BABAR detector at the PEP-II eþe− 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.
