Measurement of the e+e- -> J/psi ccbar cross section at \sqrt{s} ~10.6 GeV

P. Pakhlov

We present a new measurement of the e+e- -> J/psi ccbar cross section where the ccbar pair can fragment either into charmed hadrons or a charmonium state. In the former case the J/…

Evidence for $B^{0} \to χ_{c 1} π^{0}$ at Belle

Belle Collaboration, R. Kumar, J. B. Singh

We present a measurement of the branching fraction for the Cabibbo- and color-suppressed $B^{0} \to χ_{c 1} π^{0}$ decay based on a data sample of $657 \times 1 0^{6}$ $B B ˉ$ events colle…

Measurement of $B^{0} \to π^{+} π^{-} π^{+} π^{-}$ Decays and Search for $B^{0} \to ρ^{0} ρ^{0}$

The Belle Collaboration, C. -C. Chiang

We report on a search for the decay $B^{0} \to ρ^{0} ρ^{0}$ and other charmless modes with a $π^{+} π^{-} π^{+} π^{-}$ final state, including $B^{0} \to ρ^{0} π^{+} π^{-}$ , non-resonant $B^{0} \to 4 π^{\pm}$ , $B^0\to…

Measurement of the Moments of the Photon Energy Spectrum in B -> X_s gamma Decays and Determination of |V_cb| and m_b at Belle

Belle Collaboration, C. Schwanda, P. Urquijo +2

Using the previous Belle measurement of the inclusive photon energy in $B \to X_{s} γ$ decays, we determine the first and second moments of this spectrum for minimum photon energies in…

Observation of e+e- to K+K-J/psi via Initial State Radiation at Belle

C. Z. Yuan, Belle Collaboration

The process e+e- to K+K-J/psi is observed for the first time via initial state radiation. The cross section of e+e- to K+K-J/psi for center-of-mass energies between threshold and 6…

Search for \bar{B}^0\toΛ_c^+\barΛ_c^- decay at Belle

The Belle Collaboration, K. Abe

We search for the doubly charmed baryonic decay $B ˉ^{0} \to Λ_{c}^{+} Λ ˉ_{c}^{-}$ , in a data sample of $520 \times 1 0^{6}$ $B B ˉ$ events accumulated at the $Υ (4 S)$ resonance with the B…
