Abstract

We present the results of searches for B decays to charmless two-body final states containing η′ or ω mesons, based on 50.7fb-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+13 -11 ± 4) × 10-6, and B(B+ → ωπ+) = (6.6+2.1 -1.8 ± 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.
