英文摘要 | Based on the data sample of 33 pb(-1) collected at and around 3.773 GeV with the BESII detector at the BEPC collider, the absolute branching fractions for some exclusive semileptonic decays and inclusive decays of D mesons have been measured. With the measured branching fractions, the ratio of the two partial widths of the decays D-0 -> K-mu(+)nu(mu), and D+ -> (K) over bar mu+nu(mu) is determined to be 0.87 +/- 0.24 +/- 0.15, which supports that the isospin conversation holds in the exclusive semimuonic decays of D-0 and D- mesons. The ratio of the vector to pseudoscalar semileptonic decay rates Gamma(D+ -> (K) over bar*(0)e(+)nu(e))Gamma(D+ -> (K) over bar (0)e(+)nu(e)) is determined to be 0.57 +/- 0.17 +/- 0.02. |
