  "abstract": "The $\\eta$-$\\eta^\\prime$ mixing angle is deduced from an updated phenomenological analysis of $J/\\psi$ decays into a vector and a pseudoscalar meson. Corrections due to non-ideal $\\omega$-$\\phi$ mixing are confirmed to be crucial to find $\\theta_P=(-16.9\\pm 1.7)^\\circ$, in agreement with most recent analyses. The newly reported values of $B(J/\\psi\\to\\rho\\pi)$ by the BABAR and BES Collaborations make more difficult a reasonable description of data.",
