Search for lepton-flavor-violating τ → ℓ V0 decays at Belle

Olivier Schneider, Tagir Aushev, Chao Wang, Vladislav Balagura, Xiao Wang

We have searched for neutrinoless τ lepton decays into ℓ and V0, where ℓ stands for an electron or muon, and V0 for a vector meson (φ{symbol}, ω, K* 0, over(K, ̄)* 0 or ρ0), using 543 fb-1 of data collected with the Belle detector at the KEKB asymmetric-en ...

Measurement of the moments of the photon energy spectrum in B→Xsγ decays and determination of |Vcb| and mb at Belle

Olivier Schneider, Tagir Aushev, Chao Wang, Vladislav Balagura, Jing Li

Using the previous Belle measurement of the inclusive photon energy in B→Xsγ decays, we determine the first and second moments of this spectrum for minimum photon energies in the B meson rest frame ranging from 1.8 to 2.3 GeV. Combining these measurements ...

Jean Wicht, Aurelio Bay, Olivier Schneider, Tagir Aushev, Mingkui Wang, Chao Wang, Vladislav Balagura, Xiao Wang

We report on a search for the doubly Cabibbo suppressed decay B+→D*+π0, based on a data sample of 657×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We find no significant signal and set ...

New search for τ → μ γ and τ → e γ decays at Belle

Aurelio Bay, Olivier Schneider, Sun Hee Kim, Chao Wang

We report on a search for the lepton flavor violating τ- → μ- γ and τ- → e- γ decays based on 535 fb-1 of data accumulated at the Belle experiment. No signal is found and we set 90% confidence level upper limits on the branching ratios B (τ- → μ- γ) < 4.5 ...

Olivier Schneider, Tagir Aushev, Chao Wang, Vladislav Balagura, Xiao Wang

We report a study of the processes e+e-→J/ψD()D̄(). In J/ψDD̄ we observe a significant enhancement in the DD̄ invariant mass spectrum, which we interpret as a new charmoniumlike state and denote X(4160). The X(4160) parameters are M=(4156-20+25±15)Me ...
