Abstract

We report the first observation of B → η′X transitions with high momentum η′ mesons. We observe 39.0 ± 11.6 B decay events with 2.0 < pη′ < 2.7 GeV/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′Xs) = [6.2 ± 1.6(stat) ±1.3(syst)1.5 0.0(bkg)] × 10-4 for 2.0 < pη′ < 2.7 GeV/c.

N2 - We report the first observation of B → η′X transitions with high momentum η′ mesons. We observe 39.0 ± 11.6 B decay events with 2.0 < pη′ < 2.7 GeV/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′Xs) = [6.2 ± 1.6(stat) ±1.3(syst)1.5 0.0(bkg)] × 10-4 for 2.0 < pη′ < 2.7 GeV/c.
