Energy-Charge Correlation in the ${\pi }^{+}{\pi }^{-}{\pi }^0$ Decay of $K_L$ and of Tagged Neutral Kaons

Abstract

We relate the asymmetries in the charged pions energy in the decay into ${\pi }^{+}{\pi }^{-}{\pi }^0$ of $K_L$ and of the tagged neutral kaons. The former asymmetry is a given combination of $\Re (ϵ)$, $\Im (ϵ)$, and $|{ϵ}^{\prime }|$. Moreover, the non-violating CP asymmetry allows a test for the $\chi$PT predictions within the Zel'dovich approach for the final state interaction.
