摘要：

By a closer inspection of the massive Schwinger model within mass perturbation theory we find that, in addition to the n-boson bound states, a further type of hybrid bound states has to be included into the model. Further we explicitly compute the decay widths of the three-boson bound state and of the lightest hybrid bound state.
