Abstract

We present the first model-independent measurement of the CKM unitarity triangle angle ϕ3 using B±→ D(KS0π+π−π0) K± decays, where D indicates either a D0 or D¯ 0 meson. Measurements of the strong-phase difference of the D →KS0π+π−π0 amplitude obtained from CLEO-c data are used as input. This analysis is based on the full Belle data set of 772 × 106BB¯ events collected at the Υ(4S) resonance. We obtain ϕ3 = (5.7−8.8+10.2±3.5±5.7)° and the suppressed amplitude ratio rB = 0.323±0.147±0.023±0.051. Here the first uncertainty is statistical, the second is the experimental systematic, and the third is due to the precision of the strong-phase parameters measured from CLEO-c data. The 95% confidence ..
