Observation of Large CP Violation in the Neutral B Meson System
K. Abe, The Belle Collaboration
We present a measurement of the Standard Model CP violation parameter sin 2phi_1 based on a 29.1 fb^{-1} data sample collected at the Upsilon(4S) resonance with the Belle detector…
Observation of
K. Abe, The Belle Collaboration
We report the first observation of the decay using 21.3 fb of data collected by the Belle detector at the (4S) resonance. The preliminary result for…
Observation of B->J/psi K1(1270)
K. Abe, Belle Collaboration
We report the first observation of the exclusive decay process B->J/psi K1(1270) using a sample of 11.2M BBbar meson pairs collected in the Belle detector at the KEKB asymmetric e+…
A Measurement of the Branching Fraction for the Inclusive B --> X(s) gamma Decays with the Belle Detector
The Belle Collaboration, K. Abe
We have measured the branching fraction of the inclusive radiative B meson decay B --> X(s) gamma to be Br(B->X(s)gamma)=(3.36 +/- 0.53(stat) +/- 0.42(sys) +0.50-0.54(th)) x 10^{-4…
Measurement of Inclusive Production of Neutral Pions from Upsilon(4S) Decays
Belle Collaboration, K. Abe
Using the Belle detector operating at the KEKB e+e- storage ring, we have measured the mean multiplicity and the momentum spectrum of neutral pions from the decays of the Upsilon(4…
