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…

Prospects for R Measurement at BaBar using Radiative Return
Nicolas Berger
A precise measurement of the ratio of hadron to muon production in e^+e^- collisions, denoted by R(s), is a necessary input for the interpretation of current precision electroweak…

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…
