Measurements of Branching Fractions for B0 --> Ds+pi- and B0-bar --> Ds+K-
The Belle Collaboration, A. Das
We present improved measurements of the branching fractions for the decays B0 --> Ds+pi- and B0-bar --> Ds+K- using a data sample of 657x10^6 BB-bar events collected at the Y(4S) r…
Measurement of CP violating asymmetries in B^0 -> K^+K^- K^0_S decays with a time-dependent Dalitz approach
Belle Collaboration, Y. Nakahama, K. Sumisawa +133
We report a measurement of violating asymmetries in decays with a time-dependent Dalitz approach. This analysis is based on a data samp…
Measurement of eta eta production in two-photon collisions
S. Uehara, Y. Watanabe, H. Nakazawa +1
We report the first measurement of the differential cross section for the process gamma gamma --> eta eta in the kinematic range above the eta eta threshold, 1.096 GeV < W < 3.8 Ge…
Search for B_{s}^{0}->hh Decays at the Resonance
C. -C. Peng, P. Chang, the Belle Collaboration
We have searched for B_{s}^{0}->hh decays, where h stands for a charged or neutral kaon, or a charged pion. These results are based on a 23.6 fb^{-1} data sample collected with the…
Evidence for B- -> tau- nu_bar with a Semileptonic Tagging Method
The Belle collaboration, K. Hara, T. Iijima
We present a measurement of the decay B- -> tau- nu_bar using a data sample containing 657 million BB_bar pairs collected at the Upsilon(4S) resonance with the Belle detector at th…
Observation of Bs->Ds(*)+Ds(*)- using e+e- collisions and a determination of the Bs-Bsbar width difference ΔΓ_s
S. Esen, A. J. Schwartz, I. Adachi +125
We have made the first observation of Bs->Ds(*)+Ds(*)- decays using 23.6 fb-1 of data recorded by the Belle experiment running on the Upsilon(5S) resonance. The branching fractions…
