Observation and polarization measurement of B[superscript 0]-->a1(1260)[superscript +]a1(1260)[superscript -] decay
We present measurements of the branching fraction B and longitudinal polarization fraction fL for B0-->a1(1260)+a1(1260)- decays, with a1(1260)±-->pi-pi+pi±. The data sample, collected with the BABAR detector at the SLAC National Accelerator Laboratory, represents 465×106 produced BB̅ pairs....
