摘要
We present a search for B decays to a charged scalar meson a(0)(+) and a pi(0) where the a(0)(+) decays to an eta meson and a pi(+). The analysis was performed on a data sample consisting of 383x10(6) B (B) over bar pairs collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We find no significant signal and set an upper limit on the product branching fraction B(B+-> a(0)(+)pi(0))xB(a(0)(+)->eta pi(+)) of 1.4x10(-6) at the 90% confidence level.
