Abstract
We present a search for the rare B-meson decay B0→a1±ρ with a1±→π+π-π±. We use (110±1.2) ×106Υ(4S)→BB̄ decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We obtain an upper limit of 30×10-6(90%C.L.) for the branching fraction product B(B0→a1± ρ)B(a1±→π+π-π±), where we assume that the a1± decays exclusively to ρ0π±. © 2006 The American Physical Society.
