Title: Observation of X(3872) in B → X ( 3872 ) K π decays

Abstract

We report the first observation of B0→X(3872)(K+π–) and evidence for B+ → X(3872)(K0π+). We measure the product of branching fractions for the former to be B(B0 → X(3872)(K+π–)) × B(X(3872) → J/ψπ+π–) = (7.9 ± 1.3(stat) ± 0.4(syst)) × 10–6 and find that B0 → X(3872)K*(892)0 does not dominate the B0 → X(3872)K+π– decay mode. We also measure B(B+ → X(3872)(K0π+)) × B(X(3872) → J/ψπ+π–) = (10.6 ± 3.0(stat) ± 0.9(syst)) × 10–6. Furthermore, this study is based on the full data sample of 711 fb–1 (772 × 106BB¯ pairs) collected at the Υ(4S) resonance with the Belle detector at the KEKB collider.
