Time-dependent Dalitz Plot Measurement of CP Parameters in B0 --> Ks Pi+ Pi- Decays

Understand

We present a time-dependent Dalitz plot measurement of CP violation parameters in B0 --> Ks Pi+ Pi- decays.

• These results are obtained from a large data sample that contains 657 million BBbar pairs collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider.
• For the CP violation parameters, we obtain two consistent solutions that describe the data well.
• The first of these solutions may be preferred by external information from other measurements.
