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…

Observation of an Isotriplet of Excited Charmed Baryons Decaying to

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)…

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…
