Abstract

We present a measurement of CP asymmetry using a time-dependent Dalitz plot analysis of B0→π+π-π0 decays based on a 414fb-1 data sample containing 449×106BB̄ pairs. The data was collected on the Υ(4S) resonance with the Belle detector at the KEKB asymmetric energy e+e- collider. Combining our analysis with information on charged B decay modes, we perform a full Dalitz and isospin analysis and obtain a constraint on the CKM angle 2, 68°< 2<95° as the 68.3% confidence interval for the 2 solution consistent with the standard model (SM). A large SM-disfavored region also remains.
