Abstract

We report on a search for CP violation in the decay of D0 and D̄0 to KS 0π+π -. The data come from an integrated luminosity of 9.0 fb-1 of e+e- collisions at √s ≈ 10 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 D0 → KS 0π +π-.
