Abstract

Quantum-correlated psi(3770)->DDbar decays collected by the CLEO-c experiment are used to perform measurements of F+, the fractional CP-even content of the self-conjugate decays D->pi+pi-pi0 and D->K+K-pi0. Values of 0.973+/-0.017 and 0.732+/-0.055 are obtained for pi+pi-pi0 and K+K-pi0, respectively. The high CP-even content of D->pi+pi-pi0, in particular, makes this a promising mode for improving the precision on gamma and for measurements of CP violation in D decay.
