Patterns of CP violation from mirror symmetry breaking in the $\eta \to {\pi }^{+}{\pi }^{-}{\pi }^0$ Dalitz plot

Susan Gardner, Jun Shi

A violation of mirror symmetry in the $\eta \to {\pi }^{+}{\pi }^{-}{\pi }^0$ Dalitz plot has long been recognized as a signal of C and CP violation. Here we show how the isospin of the underlying C- and…
