摘要：

The available branching ratios for protonium annihilation into two mesons are analyzed in terms of a hadronic picture. We start from protonium wave functions calculated using a realistic OBE potential, a phenomenological part to account for the annihilation, and a particularly simple transition operator V(NNBAR --> meson(a) + meson(b)). Flavour effects, sensitivity to tensor mixing and to isospin mixing are investigated.
