Abstract
The D/sup 0/..-->..K-bar/sup 0/eta decay mode is shown to be suppressed by a large factor insensitive to eta-eta' mixing and SU(3) symmetry breaking in all transitions via intermediate states with flavor quantum numbers of a qq-bar pair, e.g., SU(3) octet, but to be roughly equal to the K-bar/sup 0/..pi../sup 0/ and K-bar/sup 0/eta' when produced via exotic qqq-barq-bar channels. The relative decay rates to K-bar/sup 0/eta, K-bar/sup 0/eta', and K-bar/sup 0/..pi../sup 0/ distinguish between models producing the additional qq-bar pair in weak or strong vertices.
