Description
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)+0.0-1.5 (bkg)]x10-4 for 2.0<pη'<2.7 GeV/c . copyright 1998 The American Physical Society
