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, A_CP = (0.43 ± 1.30) %, shows no significant CP violation.

N2 - 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.
