Abstract

For the weak nonleptonic decay K→3π, we analyze the amount of CP violation expected to arise in the Kobayashi-Maskawa model using two recently uncovered aspects: (1) quadratic terms in the K→3π amplitude (found in the CP-conserving data) and (2) electromagnetic and isospin-breaking effects in the relation of the CP-violating parameters of K→2π and K→3π. Previous to the inclusion of these effects the non-ε signal in η+-0 (η+-0=ε+ε+-0’) required interference with the highly suppressed ΔI=(3/2 amplitude; however in the present analysis the ε+-0’ signal is not suppressed. We estimate values for ε+-0’ about an order of magnitude larger than previously anticipated, although still smaller than ε.
