Search for the Decay
E391a Collaboration, J. K. Ahn
We performed a search for the decay at the KEK 12-GeV proton synchrotron. No candidate events were observed. An upper limit on the branching ratio for the de…
Measurement of CP Asymmetries and Branching Fractions in a Time-Dependent Dalitz Analysis of B^0-->(rho pi)^0 and a Constraint on the Quark Mixing Angle phi_2
The Belle Collaboration, A. Kusaka, C. C. Wang
We present the results of a time-dependent Dalitz plot analysis of B0 --> pi+ pi- pi0 decays based on a 414/fb data sample that contains 449 x 10^6 BB pairs. The data was collected…
Observation of Ds1(2536)+ -> D+pi-K+ and angular decomposition of Ds1(2536)+ -> D*+K0S
Belle Collaboration
Using 462/fb of e+e- annihilation data recorded by the Belle detector, we report the first observation of the decay Ds1(2536)+ -> D+pi-K+. The ratio of branching fractions B(Ds1+ -…
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…
Measurement of B -> D*- tau+ nu and B -> h(*) nu nubar Decays at Belle
Belle Collaboration, K. -F. Chen
We report an observation of the decay B0 -> D*- tau+ nu and a search for the rare decays B -> h(*) nu nubar\ove, where h(*) stands for a light meson. A data sample of 535 million B…
Search for new charmonium states in the processes e+ e- --> J/psi D(*) D(*) at sqrt{s} ~ 10.6 GeV
Belle Collaboration, K. Abe
We present a study of the X(3940) state in the process e+e- -> J/psi D* Dbar. The X(3940) mass and width are measured to be (3942 +7 -6 +- 6)MeV/c^2 and Gamma=(37 + 26 - 15 +- 8 Me…
