| 英文摘要 | 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. |
