Abstract
Unitarity corrections to strong decays of ψ are estimated using dispersion relations and dual model with SU(4) symmetric couplings. For ψ → ϱ π we find a suppression factor ≈ 3 × 10-4 for mD = 2 GeV. Consequences of the model for ψ → Φ π π , radiative decays and ψ′ → ordinary hadrons are pointed out.
