Pentaquarks and new hadron spectroscopy at BaBar
Stefania Ricciardi
Recent results on the search for pentaquarks and on charmonium spectroscopy at BaBar are reviewed. The latter includes the observation of the puzzling new state X(3872) -> J/psi pi…

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…
