Abstract

I shortly review the application of a recently introduced constituent quark-meson model to the determination of some strong coupling constants governing the decays of charm heavy mesons with one pion in the final state. I present the model directly through its rules for computing amplitudes. For a detailed explanation of the model, the reader is referred to the original papers.
