Abstract

We report a high-statistics measurement of the relative branching fraction B(D0→π+π−π0)/B(D0→K−π+π0) using a 532 fb−1 data sample collected with the Belle detector at the KEKB asymmetric-energy e+e− collider. The measured value of the relative branching fraction is B(D0→π+π−π0)/B(D0→K−π+π0)=(10.12±0.04(stat)±0.18(syst))×10−2, which has an accuracy comparable to the world average. We also present a measurement of the time-integrated CP asymmetry in D0→π+π−π0 decay. The result, ACP=(0.43±1.30)%, shows no significant CP violation.
