Abstract

We present measurements of branching fractions for five B-meson decays to two-body charmless final states. The data, collected with the BABAR detector at the Stanford Linear Accelerator Center, represent 459×106 BB̄ pairs. The results for branching fractions are, in units of 10-6 (upper limits at 90% C.L.), B(B+→ηρ+)=9.9±1.2±0.8, B(B0→η′ η)=0.5±0.4±0.1(<1.2), B(B0→ηπ0)=0.9±0. 4±0.1(<1.5), B(B0→η′π0)=0.9±0.4±0. 1(<1.5), and B(B0→ωπ0)=0.07±0.26±0.02(<0.5). The first error quoted is statistical and the second systematic. For the ηρ+ mode, we measure the charge asymmetry Ach(B+→ηρ+)=0. 13±0.11±0.02. © 2008 The American Physical Society.
