Measurement of Br(Bbar -> D+l-nubar) and Determination of |Vcb|

Belle Collaboration, K. Abe

We present a measurement of the branching fraction for the semileptonic B decay Bbar -> D+l-nubar, where l- can be either an electron or a muon. We find Gamma(Bbar -> D+l-nubar)= (…

Observation of Cabibbo-suppressed and W-exchange Lambda_c^+ baryon decays

Belle Collaboration, K. Abe

We present measurements of the Cabibbo-suppressed decays Lambda_c^+ --> Lambda0 K+ and Lambda_c^+ --> Sigma0 K+ (both first observations), Lambda_c^+ --> Sigma+ K+ pi- (seen with l…

Search for Direct CP Violation in B -> K pi Decays

K. Abe

We search for direct CP violation in flavor specific B -> K pi decays by measuring the rate asymmetry between charge conjugate modes. The search is performed on a data sample of 11…

Measurement of Branching Fractions for B->ππ, Kπand KK Decays

K. Abe

We report measurements of the branching fractions for $B^{0} \to π^{+} π^{-}$ , $K^{+} π^{-}$ , $K^{+} K^{-}$ and $K^{0} π^{0}$ , and $B^{+} \to π^{+} π^{0}$ , $K^{+} π^{0}$ , $K^{0} π^{+}$ and $K^{+} K ˉ^{0}$ . The results are…
