Various decay modes of the are discussed. The relations, through and the Gell-Mann-Sharp-Wagner model, between the -decay modes and the modes , are investigated, taking into account mixing. The present experimental values for the neutral branching ratios plus the shape of the Dalitz plot are shown to require a 30% contribution to the amplitude. The connection between a possible charge asymmetry in and branching ratio is investigated in the framework of a model proposed earlier by several authors. It is shown that there is no conflict between the existing data and this model. The Dalitz-plot distribution of is discussed under various assumptions about the properties of the interaction responsible for the decay.
