High statistics study of f_0(980) resonance in gamma gamma --> pi^+ pi^- production
The Belle Collaboration, K. Abe
We report on a high statistics measurement of the cross section of the process gamma gamma to pi^+ pi^- in the center-of-mass energy range 0.8 GeV/c^2 < W < 1.5 GeV/c^2 with 85.9 f…
Moments of the electron energy spectrum and partial branching fraction of decays at Belle
P. Urquijo
We report a measurement of the inclusive electron energy spectrum for charmed semileptonic decays of B mesons in a 140fb-1 data sample collected at the Υ(4S) resonance with the Bel…
A study of gamma gamma -> Ks Ks production at energies of 2.4-4.0GeV at Belle
W. T. Chen
production in two-photon collisions has been studied using a 397.6 fb data sample collected with the Belle detector at the KEKB collider. For the first…
Observation of Direct CP-Violation in B0 --> pi+pi- Decays and Model-Independent Constraints on phi2
The Belle Collaboration, H. Ishino
We present a new measurement of the time-dependent CP-violating parameters in B0 -> pi+pi- decays using a data sample that contains 535M BBbar pairs collected with the Belle detect…
