Search for CP Violation in D^0--> K_S^0 pi^+pi^-

We report on a search for CP violation in the decay of D-0 and D-0 to K(S)(0)pi(+)pi(-). The data come from an integrated luminosity of 9.0 fb(-1) of e(+)e(-) collisions at rootsapproximate to10 GeV recorded with the CLEO II.V detector. The resonance substructure of this decay is well described by ten quasi-two-body decay channels plus a small nonresonant component. We observe no evidence for CP violation in the amplitudes that describe the decay D-0-->K(S)(0)pi(+)pi(-).
