Abstract
A tentative scheme is developed to formulate the behavior of the new unstable particles. This scheme is a straightforward generalization of the usual charge-independent meson theory. The selection rules for isotopic spin are identical with those suggested by Gell-Mann. Owing to the particular form of the interaction assumed in this scheme, we can derive a new selection rule which seems to be of some use in interpreting the metastability of the new particles.
