| 英文摘要 | We report a measurement of the absolutely inclusive semileptonic branching fractions of D- and (D-0) over bar mesons, using a data sample of 22.3 pb(-1) collected with BES detector at BEPC e(+) e Collider at roots = 4.03 GeV and based on the method of "combinative D+ and D-0 single and double tags". The measured values of the branching fractions for D- --> e(-) X and (D-0) over bar --> e(-) X are ( 21.8 +/- 8.5 +/- 4.2)% and (8.9 +/- 3.0 +/- 1.6)%, respectively. The measured ratio of the branching fractions is BF(D- --> e(-) X)/BF (D0 --> e (-) X) -2.4 +/- 1.7 +/- 0.8. |
