Search for CP violating charge asymmetry in B^+ -> J/psi K^+ decays

K. Sakai, T. Kawasaki, H. Aihara +136

We present the result of a search for charge asymmetry in B^+ -> J/psi K^+ decays. The CP-violating charge asymmetry is measured to be A_CP(B^+ -> J/psi K^+) = [-0.76 +/- 0.50 (sta…

Search for $B^{0} \to K^{* 0} K^{* 0}$ , $B^{0} \to K^{* 0} K^{* 0}$ and $B^{0} \to K^{+} π^{-} K^{\mp} π^{\pm}$ Decays

C. -C. Chiang

We report a search for the decays $B^{0} \to K^{* 0} K^{* 0}$ and $B^{0} \to K^{* 0} K^{* 0}$ . We also measure other charmless decay modes with $K^{+} π^{-} K^{-} π^{+}$ and $K^{+}π^{-}K^{…

Measurement of the branching fractions and the invariant mass distributions for tau^- -> h^-h^+h^-nu_tau decays

M. J. Lee

We present a study of tau->pipipinu, tau->Kpipinu, tau->KKpinu, and tau->KKKnu decays using a 666 fb-1 data sample collected with the Belle detector at the KEKB asymmetric-energy e…
