Abstract
A study of the two-body decays B±→X_(cc)K±, where X_(cc) refers to one charmonium state, is reported by the BABAR Collaboration using a data sample of 424 fb⁻¹. The absolute determination of branching fractions for these decays are significantly improved compared to previous BABAR measurements. Evidence is found for the decay B⁺→X(3872)K⁺ at the 3σ level. The absolute branching fraction B[B⁺→X(3872)K⁺]=[2.1±0.6(stat)±0.3(syst)]×10⁻⁴ is measured for the first time. It follows that B[X(3872)→J/ψπ⁺π⁻]=(4.1±1.3)%, supporting the hypothesis of a molecular component for this resonance.
