Abstract

For the weak nonleptonic decay K3, 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 K3 amplitude (found in the CP-conserving data) and (2) electromagnetic and isospin-breaking effects in the relation of the CP-violating parameters of K2 and K3. Previous to the inclusion of these effects the non- signal in +-0 (+-0=++-0) required interference with the highly suppressed I=(3/2 amplitude; however in the present analysis the +-0 signal is not suppressed. We estimate values for +-0 about an order of magnitude larger than previously anticipated, although still smaller than .
