Estimating σ-meson couplings from D-->3π decays
Abstract
Using recent experimental evidence from E791 on the sigma meson in D-->3π decays, we study the relevant couplings in D-->σπ and σ-->ππ within the accepted theoretical framework for nonleptonic D decays, finding an overall consistency of the theory with the experimental data.
