Abstract

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 383×106 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(B0a0π+)×B(a0ηπ)<3.1×106, B(B0a0K+)×B(a0ηπ)<1.9×106, B(B0a0(1450)π+)×B(a0(1450)ηπ)<2.3×106, B(B0a0(1450)K+)×B(a0(1450)ηπ)<3.1×106, B(B0ηρ0)<1.5×106, and B(B0ηf0(980))×B(f0(980)π+π)<0.4×106.
