Abstract
Constraints on the charmed-meson mass spectrum and couplings are obtained from pole-saturated FESR. The Regge-trajectory slopes are predicted to vary inversely with respect to the mass of the lowest pseudoscalar state, while the asymptotic energy scale factors show no sign of becoming greater than the canonical 1.0 (GeV)2. Strong couplings are found to be larger than naiveSU4 predictions.
