Model-independent view on the low-mass proton-antiproton enhancement
arXiv:hep-ph/0402054 · doi:10.1103/PhysRevC.69.055205
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 NantiN experiments at LEAR. We predict a related effect in photoproduction reaction under study by CLAS collaboration.
