Model for the Violation ofCPInvariance

An explicit model for $\mathrm{CP}$ nonconservation is constructed within the framework of the current-current form of weak interactions, which has $\Delta I=\frac{1}{2}$ for the $\mathrm{CP}$-invariant part of (nonleptonic) $H_w$ with $\left|\Delta S\right|=1\mathrm{}$, violates the $\Delta I=\frac{1}{2}$ rule for the $\mathrm{CP}$-nonconserving part, and has no observable effects of $T$ nonconservation in the leptonic decay modes and the electric dipole moment of the neutron.
