In this paper we focus on the latter case where the current size of the data set demands better models. The specific case of three-kaon weak matrix elements is considered and expressed as a relatively simple structure, which generalizes naturally the concept of form factor. We propose a model for the decay $D^+ \\to K^+ K^- K^+$ as an alternative to isobar model, with free parameter predicted by the theory to be fine-tuned by a fit to data.
