Abstract
Recent CLEO results on neutral charm meson decays presented at the XXXVIth Rencontres de Moriond are discussed. We find no evidence of CP asymmetry in five different two-body decay modes of the D0 to pairs of light pseudo-scalar mesons. We present a measurement of the mixing parameter y_CP = -0.011 +- 0.025 +- 0.014 by searching for a lifetime difference between the CP neutral K+ pi- final state and the CP even K+ K- and pi+ pi- final states. Finally, we describe the first measurement of the rate of wrong-sign D0 to K+ pi- pi0 decay: R_WS = (0.43 +0.11 -0.10 +- 0.07)%.
