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.
