We have searched for lepton-flavor-violating τ decays with a pseudoscalar meson (η, η′ and π0) using a data sample of 401 fb-1 collected with the Belle detector at the KEKB asymmetric-energy e+ e- collider. No evidence for these decays is found and we set ...
We have searched for neutrinoless τ lepton decays into three charged leptons using an 87.1fb-1 data sample collected with the Belle detector at the KEKB e+e- collider. Since the number of signal candidate events is compatible with that expected from the ba ...
Several exclusive Bs0 decays are studied using a 1.86fb-1 data sample collected at the Υ(5S) resonance with the Belle detector at the KEKB asymmetric energy e+e- collider. In the Bs0→Ds-π+ decay mode we find 10 Bs0 candidates and measure the corresponding ...
We present a search for the rare decays B→h()νν̄, where h() stands for a light meson. A data sample of 535×106 BB̄ pairs collected with the Belle detector at the KEKB e+e- collider is used. Signal candidates are required to have an accompanying B meson f ...
We report a measurement of the branching fraction for the decay B + → ρ+π0 based on a 140 fb -1 data sample collected with the Belle detector at the KEKB asymmetric e+e- collider. We measure the branching fraction B(B+ →+π0) = (13.2 ± 2.3(stat)-1.9 +(syst) ...
