Three-body FSIs in D+ ---> K- pi+ pi+

Abstract

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