Such relations are widely used in phenomenological analyses of the interactions between matter and charmed mesons. We find that whilst SU(3)-flavor symmetry is accurate to 20%, SU(4) relations underestimate the D{\\rho}D coupling by a factor of fi","authors_text":"Bruno El-Bennich, Craig D. Roberts, David J.
