  "abstract": "Fitting the recent $e^+e^-\\ra\\phi\\,\\eta$ data by the Belle collaboration with a theoretical formula reveals, besides the dominant $\\phi(1680)$ resonance, two narrow resonances: expected $\\phi(2170)$ resonance and an unexpected resonance with the mass of about 1851 MeV. Close proximity to the $X(1835)$ resonance suggests that the new resonance may be interpreted as the $p \\bar p$ baryonium in an excited state. Follow-up analysis found the same resonance also in $e^+e^-\\ra\\omega\\,\\eta$ data by CMD-3 experiment.",
