We perform a study of the final-state interactions of the \( K^ + \bar{K^0}\) and the \(\bar{K^0}d\) systems in the reactions \(pp \to d K^ + \bar{K^0}\) and \(pp \to d \pi^ + \eta\). The interactions of the mesons are accounted for by using chiral unitary techniques, which generate dynamically the a 0(980)-resonance, and the \(\bar{K^0}d\) interaction is also taken into account. The amount of \(\pi^ + \eta\) versus \( K^ + \bar{K^0}\) production is shown to depend critically on the primary mixture of the two mechanisms, with large interference effects due to final-state interactions
