Spectra of prompt electrons from decays of B+ and B0 mesons and ratio of inclusive semielectronic branching fractions

T. Okabe

We present spectra of prompt electrons from decays of neutral and charged B mesons. The results are based on 140 /fb of data collected by the Belle detector on the Upsilon(4S) reso…

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 time-dependent CP violation in B0 -> J/Psi pi0 decays

S. U. Kataoka

We report a measurement of CP asymmetry parameters in the decay B0(B0bar) -> J/Psi pi0, which is governed by the b->c cbar d transition. The analysis is based on a 140/fb data samp…

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…

Time-Dependent CP Violation Effects in Partially Reconstructed $B^{0} \to D^{*} π$ Decays

T. Gershon

We report measurements of time-dependent decay rates for $B^{0} \to D^{*\mp} π^{\pm}$ decays and extraction of CP violation parameters related to $ϕ_{3}$ . We use a partial reconstruction…
