Abstract

We present the results of searches for B decays to charmless two-body final states containing η′ or ω mesons, based on 20.7fb-1 of data collected with the BABAR detector. We find the branching fractions B(B+→η′K+) = (70±8±5)×10-6, B(B0→η′K0) = (42-11+13±4)×10-6, and B(B+→ωπ+) = (6.6-1.8+2.1±0.7)×10-6, where the first error quoted is statistical and the second is systematic. We give measurements of four additional modes for which the 90% confidence level upper limits are B(B+→η′π+)<12×10-6, B(B+→ωK+)<4×10-6, B(B0→ωK0)<13×10-6, and B(B0→ωπ0)<3×10-6.
