Search for Baryonium by High Resolution Measurement of p̄p Elastic Differential Cross Section and Analysing Power from 250 MeV/c to 700 MeV/c
The study of the nuc1eon-antinucleon (NN̄) interaction is needed for a better understanding of the nature of the forces governing the nucleon-nucleon (NN) system (a subject of ordinary Nuclear physics) and, hopefully, for a more general theory of baryon-baryon interaction. Why is additional information on the NN system necessary after decades of intense experimental and theoretical work ? The answer is that conclusions regarding NN forces are drawn from the data on NN scattering and on the deuteron structure. In both cases (the deuteron is a loosely bound system) relatively large interaction distances are probed (≥ 1 fm).
