- Abstract
- We present a measurement of CP asymmetry using a time-dependent Dalitz plot analysis of B-0 ->pi(+)pi(-)pi(0) decays based on a 414 fb(-1) data sample containing 449x10(6)B(B) over bar pairs. The data was collected on the Upsilon(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 phi(2), 68 degrees <phi(2)< 95 degrees as the 68.3% confidence interval for the phi(2) solution consistent with the standard model (SM). A large SM-disfavored region also remains.
