Abstract
We measure the branching fraction for the charmless semi-inclusive process B→η′X[subscript s], where the η′ meson has a momentum in the range 2.0 to 2.7 GeV/c in the Υ(4S) center-of-mass frame and X[subscript s] represents a system comprising a kaon and zero to four pions. We find B(B→η′X[subscript s])=[3.9±0.8(stat)±0.5(syst)±0.8(model)]×10[superscript -4]. We also obtain the X[subscript s] mass spectrum and find that it fits models predicting high masses.
