Abstract:	摘要： We measure the branching fractions of B-0 -> J/psi eta((')) decays with the complete Belle data sample of 772 x 10(6) B (B) over bar events collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The results for the branching fractions are: B(B-0 -> J/psi eta) = (12.3 +/-(1.8)(1.7)+/- 0.7) x 10(-6) and B(B-0 -> J/psi eta') < 7.4 x 10(-6) at 90% confidence level. The eta-eta' mixing angle is constrained to be less than 42.2 degrees at 90% confidence level. 出版者： American Physical Society (APS) 出版日期： 2012-05-04 出處： Physical Review D, 2012-05, Vol.85 (9) 識別號： ISSN: 1550-7998 識別號： DOI: 10.1103/physrevd.85.091102
