A Search for B+ -> tau+ nu

The BABAR Collaboration, B. Aubert

We present a search for the decay B+ -> tau+ nu using 383x10^6 BBbar pairs collected at the Y(4S) resonance with the BABAR detector at the SLAC PEP-II B-Factory. A sample of events…

A Detailed Monte-Carlo Simulation for the Belle TOF System

J. W. Nam, Y. I. Choi, D. W. Kim +14

We have developed a detailed Monte Carlo simulation program for the Belle TOF system. Based on GEANT simulation, it takes account of all physics processes in the TOF scintillation…

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 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+…

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…
