Measurement of B⁰→J/ψη(') and constraint on the η-η' mixing angle
Abstract
We measure the branching fractions of B⁰→J/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(B⁰→J/ψη)=(12.3±1.811.7±0.7)×10⁻⁶ and B(B⁰→J/ψη')<7.4×10⁻⁶ at 90% confidence level. The η-η' mixing angle is constrained to be less than 42.2° at 90% confidence level.
