description

Proton-antiproton annihilations provide an excellent tool to study the dynamics of quarks and gluons in the confinement region. Annihilations at rest into two mesons show selection rules which can be related to symmetries between SU(3) invariant amplitudes. In the annihilation process not only conventional (q\(\bar{\text{q}}\)) mesons are produced but also states which do not fit into the meson nonets. It is shown how knowledge of the atomic state of the pp system at annihilation can be used to restrict the possible quantum numbers of meson resonances.
