Search for neutrinoless decays tau -> 3l
Y. Yusa
We have searched for neutrinoless tau lepton decays into three charged leptons using an 87.1 fb^{-1} data sample collected with the Belle detector at the KEKB e^+e^- collider. Sinc…
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…
Measurement of χ_{c2} Production in Two-Photon Collisions
Belle Collaboration, K. Abe
The production of the χ_{c2} charmonium state in two-photon collisions has been measured with the Belle detector at the KEKB e^+e^- collider. A clear signal for χ_{c2} --> γJ/ψ, J/…
