Abstract
We measure the branching fraction for the charmless semi-inclusive process B-->eta(')X(s), where the eta(') meson has a momentum in the range 2.0 to 2.7 GeV/c in the Y(4S) center-of-mass frame and X-s represents a system comprising a kaon and zero to four pions. We find B(B-->eta(')X(s))=[3.9+/-0.8(stat)+/-0.5(syst)+/-0.8(model)]x10(-4). We also obtain the X-s mass spectrum and find that it fits models predicting high masses.
