Measurement of the ratio Br(D0 --> pi+pi-pi0)/Br(D0 --> K-pi+pi0)
  We report a high-statistics measurement of the relative branching fraction Br(D0 --> pi+pi-pi0)/Br(D0 --> K-pi+pi0). A 357 inverse fb data sample collected with the Belle detector at the KEKB asymmetric-energy e+e- collider was used for the analysis. The relative branching fraction Br(D0 --> pi+pi-pi0)/Br(D0 --> K-pi+pi0) is determined with an accuracy comparable to the latest world average value.
