Abstract
THE generally accepted interpretation—which is the only remaining explanation within the framework of quantum mechanics—of the observed K°2→2π decays1,2 is that this is a manifestation of some CP-noninvariant interaction. Despite a large variety of suggestions as to the nature of the CP-noninvariant interaction, there has so far been no clear indication of CP-noninvariance in any other process and we still remain ignorant of the origin or nature of the interaction responsible for K°2→2π decays. A phenomenological analysis of K°→2π decays has been given by Wu and Yang3, but experiments carried out so far do not permit a unique determination of the relevant parameters. In the absence of a basic theory, it may be of interest to consider a simplifying assumption, which does not conflict with any known result, which fixes the parameters for K°→2π decay.
