Measurement of the gamma gamma -> pi+ pi- and gamma gamma -> K+ K- processes at energies of 2.4 - 4.1 GeV

H. Nakazawa

We have measured pi+pi- and K+K- production in two-photon collisions using 87.7 /fb of data collected with the Belle detector at the asymmetric energy e+e- collider KEKB. The cross…

Measurements of Branching Fractions and CP Asymmetries in B-> etah Decays

Paoti Chang

We report measurements of B to pseudoscalar-pseudoscalar decays with at least one eta meson in the final state using 140 fb^{-1} of data collected by the Belle detector at KEKB e^+…

Dalitz analysis of the three-body charmless decays B+=>K+Pi+Pi- and B+=>K+K+K-

A. Garmash

We report results on the Dalitz analysis of three-body charmless B+=>K+Pi+Pi- and B+=>K+K+K- decays based on a 140 fb $^{- 1}$ data sample collected with the Belle detector. Measurem…

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)…

Observation of B+ --> K1(1270)+ gamma

Heyoung Yang

We report the observation of the radiative decay B+ --> K1(1270)+ gamma using a data sample of 140 fb-1 taken at the Upsilon(4S) resonance with the Belle detector at the KEKB e+e-…
