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…

An Upper Bound on the Decay tau -> mu gamma from Belle
K. Abe
We have performed a search for the lepton-flavor-violating decay tau -> mu gamma using a data sample of 86.3fb^{-1} accumulated by the Belle detector at KEK. No evidence for a sign…
