Direct Measurements of Absolute Branching Fractions for D0 and D+ Inclusive Semimuonic Decays

Abstract

By analyzing about 33 $\mathrm{p}{\mathrm{b}}^{-1}$ data sample collected at and around 3.773 GeV with the BES-II detector at the BEPC collider, we directly measure the branching fractions for the neutral and charged $D$ inclusive semimuonic decays to be $BF(D^0\to {\mu }^{+}X)=(6.8\pm 1.5\pm 0.7)$ and $BF(D^{+}\to {\mu }^{+}X)=(17.6\pm 2.7\pm 1.8)$, and determine the ratio of the two branching fractions to be $\frac{BF(D^{+}\to {\mu }^{+}X)}{BF(D^0\to {\mu }^{+}X)}=2.59\pm 0.70\pm 0.25$.
