Abstract: We report measurements of the absolute branching fractions , , and , where the latter is measured for the first time. The results are based on a 121.4 fb−1 data sample collected at the Υ(10860) resonance by the Belle detector at the KEKB asymmetric-energy e e− collider. We reconstruct one meson in events and measure yields of , D0, and D mesons in the rest of the event. We obtain , , and , where the first uncertainty is statistical and the second is systematic. Averaging with previous Belle measurements gives and . For the production fraction at the Υ(10860), we find .
