Description
The quest for sources of the simultaneous violation of C and CP symmetry was popular in the 1960s and has since been mostly neglected. We revisit the operators that break C and CP for flavor-conserving transitions in both the Standard Model effective field theory and the low-energy effective field theory. Subsequently, we match these quark operators to light-meson physics using chiral perturbation theory. Applications in particular to C-odd Dalitz-plot asymmetries in $\eta \to 3\pi$ and long-distance contributions to the rare semileptonic decays $\eta \to \pi^0 \ell^+ \ell^-$ are also discussed.
