Abstract

Unitarity constraints are used to argue that

\frac{Γ (D^{0} \to {\bar{K}}^{0} η^{'})}{Γ (D^{0} \to K^{-} π^{+})} \approx 6 or 1.8

. The two choices are associated with an unresolved phase ambiguity. The non-negligible value of the above ratio points to an important role for

W

-exchange diagrams.
