No Λ oscillations
Abstract We examine a recently published calculation which predicts an oscillatory behaviour for the decay of Λ's produced together with a neutral kaon, and proposes a new expression for the wavelength of kaon strangeness oscillations. We modify the calculation by imposing the requirement that the interference of the K L and K S components of the kaon wave function occurs at a specific space-time point. With this requirement, the unusual results predicted vanish, and the conventional results are recovered.
