Abstract:
N-antiN annihilations at rest and in flight are the most productive physics tools to investigate the spectroscopy of light mesons.
The annihilations proceed from more sources of initial states, with different J^(PC) quantum numbers. This makes the interpretation of the experimental data much more difficult than in the case of other annihilation process, as for example the e+e- annihilations, and introduces ambiguities in the results.
In this talk, the possibilities to separate the N-antiN contributions of initial quantum states in different annihilation channels, are analysed.
The interference phenomena that appear are also discussed.
