Abstract

Using the N̅N potential whose real part is the transformation from Ueda-Green NN OBEP and the imaginary part is a phenomenological parametrization representing peripheral annihilation, we study N̅N, πN̅N and ππN̅N bound states. The πN̅N and ππN̅N states are considered in analogy with the πNN and ππNN bound states which explain the dibaryon experimental evidence. A lot of barionium states which have narrow widths as 10MeV as well as broad widths as 300MeV are generated. However the result is far from allowing us quantitative comparison with experimental evidence.
