The absolute inclusive semileptonic branching fraction of the D{sub s} meson has been measured based on 22.3 pb{sup {minus}1} of e{sup +}e{sup {minus}} collision data collected with the Beijing Spectrometer at {radical} (s) =4.03GeV. At this energy, the D{sub s} are produced in pairs: e{sup +}e{sup {minus}}{r_arrow}D{sub s}{sup +}D{sub s}{sup {minus}}. We reconstructed 171{plus_minus}21{plus_minus}15 D{sub s} events in five hadronic decay modes. In the recoil system of these events, several D{sub s} inclusive semileptonic decays were observed and the branching fraction is estimated to be B(D{sub s}{sup +}{r_arrow}e{sup +}X)=(7.7{sub {minus}4.3{minus}2.1}{sup +5.7+2.4}){percent}. {copyright} {ital 1997} {ital The American Physical Society}Author(s): Bai, JZ; Bardon, O; Bian, JG; Blum, I; Breakstone, A; Burnett, T; Chai, ZW; Chen, GP; Chen, HF; Chen, J; Chen, JC; Chen, SM; Chen, Y; Chen, YB; Chen, YQ; Cheng, BS; Cowan, RF; Cui, XZ; Ding, HL; Du, ZZ; Dunwoodie, W; Fan, XL; Fang, J; Fero, M; Gao, CS; Gao, ML; Gao, SQ; Gratton, P; Gu, JH; Gu, SD; Gu, WX; Gu, YF; Guo, YN; Han, SW; Han, Y; Harris, FA; He, J; He, JT; He, M; Hitlin, DG; Hu, GY; Hu, JL; Hu, QH; Hu, T; Hu, XQ; Huang, XP; Huang, YZ; Izen, JM; Jia, QP; Jiang, CH; Jin, S; Jin, Y; Jones, L; Kang, SH; Ke, ZJ; Kelsey, MH; Kim, BK; Kong, D; Lai, YF; Lan, HB; Lang, PF; Lankford, A; Li, J; Li, PQ; Li, Q; Li, RB; Li, W; Li, WD; Li, WG; Li, XH; Li, XN; Lin, SZ; Lu, F; Liu, HM; Liu, J; Liu, JH; Liu, Q; Liu, RG; Liu, Y; Liu, ZA; Lou, XC; Lowery, B; Lu, JG; Lu, JY; Luo, SQ | Abstract: The absolute inclusive semileptonic branching fraction of the [Formula presented] meson has been measured based on [Formula presented] of [Formula presented] collision data collected with the Beijing Spectrometer at [Formula presented] At this energy, the [Formula presented] are produced in pairs: [Formula presented] We reconstructed [Formula presented] [Formula presented] events in five hadronic decay modes.
