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 r_B = 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 interval on ϕ₃ is (−29.7, 109.5)^°, which is consistent with the current world average. [Figure not available: see fulltext.]
