摘要

Using the data sample of about 33 pb−1 collected at and around 3.773 GeV with the BES-II detector at the BEPC collider, we have studied inclusive K¯0/K0 and K∗(892)∓ decays of D0 and D+ mesons. The branching fractions for the inclusive K¯0/K0 and K∗(892)− decays are measured to be BF(D0→K¯0/K0X)=(47.6±4.8±3.0)%, BF(D+→K¯0/K0X)=(60.5±5.5±3.3)%, BF(D0→K∗−X)=(15.3±8.3±1.9)% and BF(D+→K∗−X)=(5.7±5.2±0.7)%. The upper limits of the branching fractions for the inclusive K∗(892)+ decays are set to be BF(D0→K∗+X)<3.6% and BF(D+→K∗+X)<20.3% at 90% confidence level.
