Observation of B0 Meson decays to a1(1260) pi
B. Aubert, BaBar Collaboration
We present a preliminary measurement of the branching fraction of the B meson decay B0--> a1(1260)+ pi- with a1(1260)+ --> pi+ pi+ pi- . The data were recorded with the BaBar detec…
A Measurement of the B0 --> J/psi pi+pi- Branching Fraction
The BABAR Collaboration, B. Aubert
We present a preliminary measurement of the branching fraction for the decay of the neutral meson into the final state J/. The data set contains approximately 56 milli…
First Year of the BABAR Experiment Data Taking
Marc Verderi
The BABAR experiment at the PEP-II asymmetric B factory observed its first hadronic events on the 26th of May 1999. We present the progress made so far on the data taking, the BABA…
Measurement of the time dependence of B^0-anti-B^0 oscillations using inclusive dilepton events
The BABAR Collaboration, B. Aubert
A preliminary study of time dependence of B^0-anti-B^0 oscillations using dilepton events is presented. The flavor of the B meson is determined by the charge sign of the lepton. To…
