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 [rapid communication]
Abstract
The branching fractions for the inclusive Cabibbo-favored K and Cabibbo-suppressed K 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→K(892)X and D→K(892)X are determined to be BF(D→KX)=(8.7±4.0±1.2)%, BF(D→KX)=(23.2±4.5±3.0)% and BF(D→KX)=(2.8±1.2±0.4)%. An upper limit on the branching fraction at 90% C.L. for the decay D→K(892)X is set to be BF(D→KX)<6.6%.
