Decay Modes of a (θ+θ¯) System

Relations among the different states of a system consisting of a $\theta$ meson, a $\overline{\theta }$ meson, and a certain number of pions are discussed. Theorems concerning certain correlations between the production probabilities for charged and uncharged $\theta$ mesons and the decay modes (${{\theta }_1}^0$ and ${{\theta }_2}^0$) are obtained.
