Some Consequences of the ProposedCandTViolations in Electromagnetic Interactions

Abstract

The model in which $C$ and $T$ are violated in the electromagnetic interactions of hadrons is considered further. It is shown that in this model, the nucleons should have electric dipole moments of order ${10}^{-19\mathrm{}}\mathrm{cm}\times e$, comparable to the present upper limit for the neutron electric dipole moment. The effect of mixing between ${\eta }^0$ and $X^0\mathrm{}\left(960\right)\mathrm{}$ on the decays ${\eta }^0\to {\pi }^0{e}^{+}{e}^{-}$, $X^0\to {\pi }^0{e}^{+}{e}^{-}$, and $X^0\to {\eta }^0{e}^{+}{e}^{-}$ is discussed, and some estimates for the branching ratios are presented. It is found that the branching ratios of these to all ${\eta }^0$ and $X^0$ decays may be about 1%.
