- W1480070015 abstract "We present preliminary results of several analyses searching for the effects of CP violation and mixing in the decay of D0 mesons. We find no evidence of CP asymmetry in five different two-body decay modes of the D0 to pairs of light pseudo-scalar mesons: A_CP(K+ K-) = (+0.05 +- 2.18 +- 0.84)%, A_CP(pi+ pi-) = (+2.0 +- 3.2 +- 0.8)%, A_CP(K0_S pi0) = (+0.1 +- 1.3)%, A_CP(pi0 pi0) = (+0.1 +- 4.8)% and A_CP(K0_S K0_S) = (-23 +- 19)%. We present the first measurement of the rate of wrong-sign D0 -> K+ pi- pi0 decay: R_WS = 0.0043 + 0.0011 - 0.0010 +- 0.0007. Finally, we describe a measurement of the mixing parameter y_CP= Delta Gamma / (2 Gamma) 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. Under the assumption that CP is conserved we find y_CP = -0.011 +- 0.025 +- 0.014." @default.
