The CP violating effects observed thus far appear only in flavor-changing processes and in a manner consistent with the predictions of the Standard Model (SM). The observed baryon asymmetry of the universe suggests that new mechanisms of CP violation beyond the SM should appear. Most searches for new sources of CP violation focus on processes that break P and CP, whereas processes that would break C and CP are not well studied. The decay η →π+ π- π0 is an ideal process in which to search for C and CP violation. In this talk, I will analyze the C and CP violating patterns in the Dalitz plot distribution of η → π+ π- π0decay and discuss the implications of existing experiments.
