Can the observed enhancement in the mass spectrum of p \bar p in J/ψ\to γp \bar p be interpreted by a possible p \bar p bound state

Provided the enhancement in the $p\bar{p}$ spectrum in radiative decay $J/\psi \to \gamma p\bar{p}$ observed by the BES collaboration is due to an existence of a $p\bar{p}$ molecular stat…
