Abstract

We stress the importance of three-body final state interactions in D⁺ → K^- \p⁺ \p⁺. The basic building block is the Kπ amplitude with parameters determined by a fit to elastic LASS data. Based on a vector weak vertex, we can describe the Kπ phase production experimental in the elastic region.
