The\(N\bar N\) and ππ decay modes of baryonium

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

A non-relativistic quark model is used to calculate the decay widths of baryonium states to\(N\bar N,N\bar \Delta \),\(N\bar N,N\bar \Delta \) and\(\Delta \bar \Delta \). Large widths are found and used to estimate the\(\bar pp\) and\(\bar pn\) elastic cross-sections. The couplings of baryonium states to two identical mesons are also investigated.
