Abstract

We report on a search for CP violation in the decay of D⁰ and D̄⁰ to K_S 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 → K_S ⁰π ⁺π^-.
