Abstract
The discovery of hadrons bearing new quantum numbers (''charm,'' collectively) would open up new possibilities to pursue the issue of CP violation. The matter of CP signatures for charm-changing processes is discussed in general, model-independent terms save for the assumption that $delta$C/$delta$Q = 1 in semileptonic channels. We note certain qualitative differences in the analysis, as compared to charm-conserving reactions. We then raise the issue of indirect effects of CP violation in charm-changing interactions on the neutral K-meson system. In particular, an example is discussed in which CP symmetry breakdown is located in the charm-changing interactions and in which the present CP evidence for charm-conserving decays is qualitatively accommodated. The operational distinctions between this mechanism and another interesting possibility, the presence of a ''second'' superweak interaction (one with abs. value of $delta$C = 2), turn out to be delicately linked to CP tests for exclusive decay processes.
