Abstract

We present a time-dependent Dalitz plot measurement of CP violation parameters in B0→KS0π+π- decays. These results are obtained from a large data sample that contains 657×106 BB̄ pairs collected at the Υ(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. There is no evidence for direct CP violation in B0→ρ0(770)KS0, B0→f0(980)KS0 and B0→K*+(892)π-, while measurements of mixing-induced CP violation in B0→ρ0(770)KS0 and B0→f0(980)KS0 decays are consistent with that of b→cc̄s decays. We also measured the phase difference between B0→K*+(892)π- and B̄0→K*-(892)π+, which may be used to extract 3.

N2 - We present a time-dependent Dalitz plot measurement of CP violation parameters in B0→KS0π+π- decays. These results are obtained from a large data sample that contains 657×106 BB̄ pairs collected at the Υ(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. There is no evidence for direct CP violation in B0→ρ0(770)KS0, B0→f0(980)KS0 and B0→K*+(892)π-, while measurements of mixing-induced CP violation in B0→ρ0(770)KS0 and B0→f0(980)KS0 decays are consistent with that of b→cc̄s decays. We also measured the phase difference between B0→K*+(892)π- and B̄0→K*-(892)π+, which may be used to extract 3.
