Although the result of this work has recently been dismissed experimentally in connection with the sign of asymmetry parameters, this does not necessarily mean the disproval of the model. For this point, see J. Iizuka and R. Oehme, preprint.

This assumption does not appear in the Sachs model of the nucleons because of the linear p-wave coupling condition. Since there is no transition of the type Λ↔Λ+ π, we must impose this sort of conditions in our model.
