dc.descriptionProvided the enhancement in the $p \bar{p}$ spectrum in radiative decay $J/ψ\to γp \bar{p}$ observed by the BES collaboration is due to an existence of a $p \bar{p}$ molecular state, we calculate its binding energy and lifetime in the linear $σ$ model. We consider a possibility that the enhancement is due to a $p \bar p$ resonance which is in either S-wave or P-wave structure and compare our results with the data.
