Study of the Suppressed Decays $B^{-} \to [K^{+} π^{-}]_{D} K^{-}$ and $B^{-} \to [K^{+} π^{-}]_{D} π^{-}$

M. Saigo

We report a study of the suppressed decays $B^{-} \to [K^{+} π^{-}]_{D} K^{-}$ and $B^{-} \to [K^{+} π^{-}]_{D} π^{-}$ , where $[K^{+} π^{-}]_{D}$ indicates that the $K^{+} π^{-}$ pair originates from a neutral $D$ …

Evidence for Direct CP Violation in B0 -> K+- pi-+ Decays

Y. Chao

We report evidence for direct CP violation in the decay B0 -> K+-pi-+ with 253/fb of data collected with the Belle detector at the KEKB e+e- collider. Using 275 million B B_bar pai…

Observation of $B^{0} \to D^{-} (5 π)^{+}$ , $B^{+} \to D^{-} (4 π)^{++}$ and $B^{+} \to D ˉ^{* 0} (5 π)^{+}$

G. Majumder

We report the first observation of a number of decay modes of the B meson, namely $B^{0} \to D^{*-} (5 π)^{+}$ , $B^{+} \to D^{*-} (4 π)^{++}$ and $B^{+} \to D ˉ^{* 0} (5 π)^{+}$ , where $(nπ)…

Study of B0 -> rho+-pi-+ Time-dependent CP Violation at Belle

C. C. Wang

We present a time-dependent analysis of CP violation in B0 -> rho pi decays based on a 140 1/fb data sample collected at the Y(4S) resonance with the Belle detector at the KEKB asy…

Search for D^0-D^0bar mixing in D^0 -> K+pi- decays and measurement of the doubly-Cabibbo-suppressed decay rate

J. Li, Z. P. Zhang, A. J. Schwartz

We have searched for mixing in the D0-D0bar system by measuring the decay-time distribution of D0->K+pi- decays. The analysis uses 90 fb^{-1} of data collected by the Belle detecto…

Observation of B+ to Lambda Lambdabar K+

Y. -J. Lee, M. -Z. Wang

We report the first observation of the charmless hyperonic B decay, B^+ --> Lambda Lambdabar K^+, using a 140 fb^-1 data sample recorded at the Upsilon(4S) resonance with the Belle…
