Observation and polarization measurement of B-0 -> a(1)(1260)(+)a(1)(1260)(-) decay

We present measurements of the branching fraction B and longitudinal polarization fraction fL for B0→a1(1260)+a1(1260)- decays, with a1(1260)±→π-π+π±. The data sample, collected with the BABAR detector at the SLAC National Accelerator Laboratory, represents 465×106 produced BB̄ pairs. We measure B(B...
