Abstract:

Cabibbo-favored nonleptonic charmed particle decays exhibit large final-state phase differences in

\bar K \pi

and

\bar K^* \pi

but not

\bar K \rho

channels. It is of interest to know the corresponding pattern of final-state phases in doubly-Cabibbo-suppressed decays, governed by the

c \to d u \bar s

subprocess. An experimental program is outlined for determining such phases via measurements of rates for

D \to K^* \pi

and

K (\rho, \omega,\phi)

channels, and determination of interference between bands in Dalitz plots. Such a program is feasible at planned high-intensity sources of charmed particles.
