Study of Three-Body Y(10860) Decays

I. Adachi, K. Adamczyk, H. Aihara +337

We report preliminary results on the analysis of the three-body Y(10860)=> B barB pi, Y(10860) => (B barB* + c.c.) pi and Y(10860)=> B* barB* pi decays including an observation of…

Evidence for a Zb0(10610) in Dalitz analysis of Y(5S) -> Y(nS) pi0 pi0

I. Adachi, K. Adamczyk, H. Aihara +331

We report the first observation of Y(5S) -> Y(1,2S) pi0 pi0 decays. Evidence for the Zb0(10610) with 4.9sigma significance is found in a Dalitz plot analysis of Y(5S) -> Y(2S) pi0…

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…

Evidence for B- -> Ds+ K- l- nubar and search for B- -> Ds*+ K- l- nubar

Belle Collaboration, J. Stypula, M. Rozanska +165

We report measurements of the decays B- -> Ds(*)+ K- l- nubar in a data sample containing 657x10^6 BBbar pairs collected with the Belle detector at the KEKB asymmetric-energy e+e-…

Measurement of $B^{0} \to J / ψ η^{(}^{'}^{)}$ and Constraint on the $η - η^{'}$ Mixing Angle

M. -C. Chang, Y. -C. Duh, J. -Y. Lin +153

We measure the branching fractions of $B^{0} \to J / ψ η^{(}^{'}^{)}$ decays with the complete Belle data sample of $772 \times 1 0^{6}$ $B B ˉ$ events collected at the $Υ (4 S)$ res…
