Low-Mass Proton-Antiproton Enhancement: Belle and BES Results, Premises of LEAR and Expectations from CLAS

الأصل · EN

We present a simple explanation for the recently observed near-threshold proton-antiproton enhancement. It is described by a set of low-energy parameters deduced from the analysis of NantiN experiments at LEAR. We predict a related effect in photoproduction reaction under study by CLAS collaboration.
