Abstract

We report the first observation of B → η′X transitions with high momentum η′ mesons. We observe 39.0 ± 11.6B decay events with 2.0 < p_η′ < 2.7GeV/c, the high momentum region where background from b → c processes is suppressed. We discuss the physical interpretation of the signal, including the possibility that it is due to b → sg* transitions. Given that interpretation, we find B(B → η′X_s) = [6.2 ± 1.6(stat) ± 1.3(syst)^+0.0 _-1.5(bkg)] × 10^-4 for 2.0 < p_η′ < 2.7GeV/c.
