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.
