Abstract

By analyzing approximately 33 pb(-1) of sample data collected at and around 3.773 GeV with the BES-II detector at the BEPC collider, we directly measured the branching fractions for the neutral and charged D inclusive semimuonic decays to be BF(D-0 -> mu(+) X) = (6.8 +/- 1.5 +/- 0.8)% and BF(D+ -> mu(+) X) (17.6 +/- 2.7 +/- 1.8)%, and determined the ratio of the two branching fractions to be BF(D+->mu(+) X)/BF(D-0 ->mu(+) X) = 2.59 +/- 0.70 +/- 0.25.
