SU(N) Elastic Rescattering in B and D Decays


The treatment of elastic final state interactions (FSI) under a symmetry group is presented. The proposed method is based on Watson’s theorem, i.e. on symmetry properties of the S-matrix and on its unitarity. This theorem provides an easy way to introduce rescattering effects by defining final state interactions mixing matrices. A symmetry group fixes the… (More)
