Using a 4-dimensional approach, the couplings of the strongly interacting particles are restricted in a simple way which is not inconsistent with experiment. This leads to the consideration of a Goldhaber-type model. The gross properties of the hyperons are calculated in the intermediate-coupling approximation for this model.
