Measurement of branching fractions for the inclusive Cabibbo-favored K¯∗0(892) and Cabibbo-suppressed K∗0(892) decays of neutral and charged D mesons

The branching fractions for the inclusive Cabibbo-favored K¯∗0 and Cabibbo-suppressed K∗0 decays of D mesons are measured based on a data sample of 33 pb−1 collected at and around the center-of-mass energy of 3.773 GeV with the BES-II detector at the BEPC collider. The branching fractions for the decays D+(0)→K¯∗0(892)X and D0→K∗0(892)X are determined to be BF(D0→K¯∗0X)=(8.7±4.0±1.2)%, BF(D+→K¯∗0X)=(23.2±4.5±3.0)% and BF(D0→K∗0X)=(2.8±1.2±0.4)%. An upper limit on the branching fraction at 90% C.L. for the decay D+→K∗0(892)X is set to be BF(D+→K∗0X)<6.6%.
