Abstract

In a sample of 6.6×10⁶ produced B mesons we have observed decays B→η′K, with branching fractions B(B⁺→η′K)=(6.5^+1.5_-1.4±0.9)×10^-5 and B(B⁰→η′K)=(4.7^+2.7_-2.0±0.9)×10^-5. We have searched with comparable sensitivity for 17 related decays to final states containing an η or η′ meson accompanied by a single particle or low-lying resonance. Our upper limits for these constrain theoretical interpretations of the B→η′K signal.

We have searched with comparable sensitivity for 17 related decays to final states containing an η or η′ meson accompanied by a single particle or low-lying resonance. Our upper limits for these constrain theoretical interpretations of the B→η′K signal.
