Abstract

The BES collaboration has recently observed a strong enhancement close to the proton-antiproton, threshold in the J/ψ decays into . Such a structure can be explained by a traditional nucleon-antinucleon, , model. The near threshold ¹¹S₀ bound state and/or the well-established ¹³P₀ resonant state found in this interaction can adequately describe the BES data.
