Evidence for Direct CP Violation in B0 -> K+- pi-+ Decays
Y. Chao
We report evidence for direct CP violation in the decay B0 -> K+-pi-+ with 253/fb of data collected with the Belle detector at the KEKB e+e- collider. Using 275 million B B_bar pai…
Observation of Large CP Violation and Evidence for Direct CP Violation in B0-->pi+pi- Decays
K. Abe
We report the first observation of CP-violating asymmetries in B0 --> pi+pi- decays based on a 140 fb-1 data sample collected at the Upsilon(4S) resonance with the Belle detector a…
Improved Measurement of Mixing-induced CP Violation in the Neutral B Meson System
The Belle Collaboration, K. Abe
We present an improved measurement of the standard model CP violation parameter sin2phi_1 (also known as sin2beta) based on a sample of 85 times 10^6 B Bbar pairs collected at the…
Observation of B -> D^{(*)} K^- K^{0(*)} decays
Belle Collaboration, A. Drutskoy
The B -> D^{(*)} K^- K^{(*)0} decays have been observed for the first time. The branching fractions of the B -> D^{(*)} K^- K^{(*)0} decay modes are measured. Significant signals a…
Measurement of the Oscillation Frequency for B0-Bobar Mixing using Hadronic B0 Decays
Belle Collaboration, T. Tomura
The oscillation frequency of B0-B0bar mixing (Delta-m_d) has been measured using 29.1 fb^{-1} of datacollected with the Belle detector at KEKB. This measurement is made through the…
Observation of B+- -> omega K+- Decay
R. -S. Lu
We report the first observation of the charmless two-body mode decay, and a new measurement of the branching fraction for the decay. T…
