Observation of ψ(4040) and ψ(4160) decay into ηJ/ψ

Belle Collaboration, X. L. Wang, Y. L. Han +126

The cross section for e^+e^- \to ηJ/ψbetween \sqrt{s}=3.8 GeV/c^2 and 5.3 GeV/c^2 is measured via initial state radiation using 980 fb^{-1} of data on and around the Υ(nS)(n=1,2,3,…

Search for B -> phi pi decays

Belle collaboration, J. H. Kim, M. Nakao +149

We report on a search for the charmless decays $B^{+} \to ϕ π^{+}$ and $B^{0} \to ϕ π^{0}$ that are strongly suppressed in the Standard Model. The analysis is based on a data sample of…

Search for the decay $B^{0} \to D K^{* 0}$ followed by $D \to K^{-} π^{+}$

The Belle Collaboration, K. Negishi, Y. Horii +136

We report a study of the decay $B^{0} \to D K^{+} π^{-}$ followed by $D \to K^{-} π^{+}$ , where $D$ indicates $D^{0}$ or $D ˉ^{0}$ . We reconstruct the $D K^{+} π^{-}$ state in a phase…

Evidence for the eta_b(2S) and observation of h_b(1P) -> eta_b(1S) gamma and h_b(2P) -> eta_b(1S) gamma

Belle Collaboration, R. Mizuk, D. M. Asner +171

We report the first evidence for the eta_b(2S) using the h_b(2P)->eta_b(2S)gamma transition and the first observation of the h_b(1P)->eta_b(1S)gamma and h_b(2P)->eta_b(1S)gamma tra…

Measurement of gamma gamma* --> pi0 transition form factor at Belle

The Belle Collaboration, S. Uehara, Y. Watanabe +158

We report a measurement of the process gamma gamma* --> pi0 with a 759 fb^{-1} data sample recorded with the Belle detector at the KEKB asymmetric-energy e+e- collider. The pion tr…

Measurements of Branching Fractions and Time-dependent CP Violating Asymmetries in $B^{0} \to D^{(*) \pm} D^{\mp}$ Decays

Belle Collaboration, M. Röhrken, I. Adachi +161

We report measurements of branching fractions and time-dependent CP asymmetries in $B^{0} \to D^{+} D^{-}$ and $B^{0} \to D^{*\pm} D^{\mp}$ decays using a data sample that contains $…

First observation of $B_{s}^{0} \to J / ψ η$ and $B_{s}^{0} \to J / ψ η^{'}$

Jin Li

We report first observations of $B_{s}^{0} \to J / ψ η$ and $B_{s}^{0} \to J / ψ η^{'}$ . The results are obtained from 121.4 fb^{-1} of data collected at the $Υ (5 S)$ resonance with the Belle detector…
