Abstract
The resonant substructure in D-0-> K(S)(0)pi(+)pi(-) decays is described by a combination of ten quasi two-body intermediate states which include both CP-even and CP-odd eigenstates and one doubly Cabibbo suppressed channel. We present a formalism that connects the variation in D-0 decay time over the Dalitz plot with the mixing parameters, x and y, that describe off-shell and on-shell D-0-(D) over bar (0) mixing. We analyze the CLEO II.V data sample and find the parameters x and y are consistent with zero. We limit (-4.5 < x < 9.3)% and (-6.4 < y < 3.6)% at the 95% confidence level.
