Abstract
Using the 9fb-1 data sample collected with the CLEO II.V detector at the Cornell Electron Storage Ring, we study the resonant substructure of the Cabibbo suppressed decay D 0 → pi+pi-pi 0. We observe significant contributions from the rho- pi+, rho+pi-, rho 0pi0, and non-resonant channels, and present results of the amplitudes, phases, and fit fractions for these and other sub-modes. No significant evidence for the sigma(500) or any other resonance was found. ACP has been measured as 0.01+0.09-0.07 +/- 0.09.
