Abstract

We present a simple interpretation of the recently observed near-threshold proton-antiproton enhancement. It is described by a set of low-energy parameters deduced from the analysis of NN experiments at the Low Energy Antiproton Ring. We predict a related effect in photoproduction reaction under study by CLAS Collaboration.
