Abstract

This paper discusses the parity of charged pions. It is shown that the original determination of the parity of the negatively charged pion using the capture of negatively charged pions in deuterium to form two neutrons is not conclusive if the pion has a complex substructure. It is demonstrated that this experiment is compatible with the mixed-parity nature of the π^- arising in a recent composite model. A major consequence of this is that CP may be conserved in the K⁰-K⁰ system.
