Abstract

We present a search for B decays to charmless final states involving charged or neutral a0 mesons. The data sample corresponds to 89×106 BB̅ pairs collected with the BABAR detector operating at the PEP-II asymmetric-energy B Factory at Stanford Linear Accelerator Center. We find no significant signals and determine the following 90% C.L. upper limits: B(B0→a0-π+)<5.1×10-6, B(B0→a0-K+)<2.1×10-6, B(B-→a0-K̅ 0)<3.9×10-6, B(B+→a00π+)<5.8×10-6, B(B+→a00K+)<2.5×10-6, and B(B0→a00K0)<7.8×10-6, where in all cases B indicates the product of branching fractions for B→a0X and a0→ηπ, where X indicates K or π.
