Study of B^0 -> rho^0 rho^0 decays, implications for the CKM angle phi_2 and search for other B^0 decay modes with a four-pion final state
The Belle Collaboration, P. Vanhoefer, J. Dalseno +171
We present a study of the branching fraction of the decay B^0->rho0rho0 and the fraction of longitudinally polarized rho0 mesons in this decay. The results are obtained from the fi…
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,…
Study of the Hadronic Transitions (2S)(1S) at Belle
Belle Collaboration, U. Tamponi, R. Mussa +131
We study the rare hadronic transitions and using a sample of 158 decays collected with the Belle detecto…
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 and that are strongly suppressed in the Standard Model. The analysis is based on a data sample of…
