Description

We present a search for B0 decays to charmless final states involving an η meson, a charged pion, and a second charged pion or kaon. The data sample corresponds to 383x106 BB pairs collected with the BABAR detector operating at the PEP-II asymmetric-energy B factory at SLAC. We find no significant signals and determine the following 90% C.L. upper limits: B(B0→a0-π+)xB(a0-→ηπ-)<3.1x10-6, B(B0→a0-K+)xB(a0-→ηπ-)<1.9x10-6, B(B0→a0(1450)-π+)xB(a0(1450)-→ηπ-)<2.3x10-6, B(B0→a0(1450)-K+)xB(a0(1450)-→ηπ-)<3.1x10-6, B(B0→ηρ0)<1.5x10-6, and B(B0→ηf0(980))xB(f0(980)→π+π-)<0.4x10-6
