First measurement of the CKM angle ϕ 3 withS B ± → D(KS0 π + π π 0 ) K ± decays

Journal Article (Journal Article)

We present the first model-independent measurement of the CKM unitarity triangle angle ϕ using B → D(KS0π π π ) K decays, where D indicates either a D or D¯ meson. Measurements of the strong-phase difference of the D →KS0π π π amplitude obtained from CLEO-c data are used as input. This analysis is based on the full Belle data set of 772 × 10 BB¯ events collected at the Υ(4S) resonance. We obtain ϕ = (5.7−8.8+10.2±3.5±5.7) and the suppressed amplitude ratio r = 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 ϕ is (−29.7, 109.5) , which is consistent with the current world average. [Figure not available: see fulltext.] 3 3 B 3 ± + − 0 ± 0 0 + − 0 6 ° °
