Abstract
By analyzing an e+e-annihilation data sample with an integrated luminosity of 2.93 fb-1 taken at the center-of-mass energy of 3.773 GeV with the BESIII detector, we determine the absolute branching fractions of the hadronic decays D0→K-π+ω, D0→KS0π0ω, and D+→KS0π+ω to be (3.392±0.044stat±0.085syst)%, (0.848±0.046stat±0.031syst)%, and (0.707±0.041stat±0.029syst)%, respectively. The accuracy of the branching fraction measurement of the decay D0→K-π+ω is improved by a factor of seven compared to the world average value. The D0→KS0π0ω and D+→KS0π+ω decays are observed for the first time.
