چکیده
We examine a recently published calculation which predicts an oscillatory behaviour for the decay of Λs 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. When neutral kaons are produced in a hadronic reaction, strangeness conservation dictates that the kaons are produced in one of the strangeness eigenstates, either a K 0 or a ¯ K 0. For example, the reactions

More nonperturbative corrections to the fine and hyperfine splitting in the heavy quarkonium Abstract The leading nonperturbative effects to the fine and hyperfine splitting (for n=2) have been calculated recently. We point out that a contribution of the same order O(Λ 4 QCD /m 3 α 2 s) has been overlooked. We calculate it in this paper.
