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 $D$ …

Observation of an Isotriplet of Excited Charmed Baryons Decaying to $Λ_{c}^{+} π$

R. Mizuk

We report the observation of an isotriplet of excited charmed baryons, decaying into Lambda_c+ pi-, Lambda_c+ pi0 and Lambda_c+ pi+. We measure the mass differences M(Lambda_c+ pi)…

Study of decay mechanisms in B- -> Lambda_c+ pbar pi- decay and observation of low mass structure in the (Lambda_c+ pbar) system

The Belle Collaboration, N. Gabyshev

Using a sample of 152 million BBbar pairs accumulated with the Belle detector at the KEKB e+e- collider, we perform a Dalitz plot analysis of the three-body charmed decay B- -> Lam…

Improved Measurements of Partial Rate Asymmetry in B -> h h Decays

Y. Chao, P. Chang

We report improved measurements of the partial rate asymmetry (Acp) in B -> h h decays with 140fb^-1 of data collected with the Belle detector at the KEKB e+e- collider. Here h sta…

Study of double charmonium production in e^+ e^- annihilation at \sqrt{s} ~ 10.6 GeV

K. Abe

We present a new analysis of double charmonium production in e^+ e^- annihilation. The observation of the processes e^+ e^- -> J/psi eta_c, J/psi chi_c0, and J/psi eta_c(2S) is con…

Measurement of the B --> K^* gamma Branching Fractions and Asymmetries

Mikihiko Nakao

We report measurements of the radiative decay B --> K^*γ. The analysis is based on a data sample containing 85.0*10^6 B meson pairs collected by the Belle detector at the KEKB stor…
