Abstract

We measure the branching fractions of B0J/ψη() decays with the complete Belle data sample of 772×106 BB¯ events collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e collider. The results for the branching fractions are: B(B0J/ψη)=(12.3±1.71.8±0.7)×106 and B(B0J/ψη)<7.4×106 at 90% confidence level. The ηη mixing angle is constrained to be less than 42.2° at 90% confidence level.
