Abstract

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 x 10⁶ BB̅ 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 B⁰ → J/ψϕ and find no evidence of a signal.
