Search for lepton flavor violating decays τ- → ℓ- π0, ℓ- η, ℓ- η′

Olivier Schneider, Sun Hee Kim, Chao Wang, Sanjeev Kumar, Lei Zhang, Jing Li

We have searched for lepton flavor violating semileptonic τ- decays using a data sample of 153.8 fb-1 accumulated with the Belle detector at the KEKB e+e- collider. For the six decay modes studied, the observed yield is compatible with the estimated backgr ...

Observation of B-→J/ψΛp̄ and searches for B-→J/ψΣ0p̄ and B0→J/ψpp̄ decays

Olivier Schneider, Sun Hee Kim, Tagir Aushev, Mingkui Wang, Stewart Cole, Chao Wang, Yuan Yuan, Lei Zhang, Ji Hyun Kim, Jing Li

We report the observation of B-→J/ψΛp̄ and searches for B-→J/ψΣ0p̄ and B0→J/ψpp̄ decays, using a sample of 275×106 BB̄ pairs collected with the Belle detector at the Υ(4S) resonance. We observe a signal of 17.2±4.1 events with a significance of 11.1σ and o ...

Time-dependent CP-violating asymmetries in b→sq q transitions

Aurelio Bay, Olivier Schneider, Sun Hee Kim, Tagir Aushev, Mingkui Wang, Chao Wang, Sanjeev Kumar, Lei Zhang, Jing Li

We present new measurements of CP-violation parameters in B0→K0, K+K-KS0, f0(980)KS0, η′KS0, ωKS0, and KS0π0 decays based on a sample of 275×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. ...

Branching fraction, polarization and CP-violating asymmetries in B 0→D+D- decays

Aurelio Bay, Olivier Schneider, Sun Hee Kim, Tagir Aushev, Mingkui Wang, Chao Wang, Vladislav Balagura, Lei Zhang, Ji Hyun Kim, Jing Li

We present measurements of the branching fraction, the polarization parameters and CP-violating asymmetries in B0→D*+D *- decays using a 140 fb-1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collid ...
