英文摘要	We present a measurement of D-0-(D) over bar (0) mixing parameters using the ratios of lifetimes extracted from samples of D-0 mesons decaying to K(-)pi(+), K-K+, and pi(-)pi(+). Using 91 fb(-1) of data collected by the BABAR detector at the PEP-II asymmetric-energy B Factory, we obtain a value Y=[0.8+/-0.4(stat.)(-0.4)(+0.5)(syst.)]%, which, in the limit of CP conservation, corresponds to the mixing parameter y=DeltaGamma/2Gamma. Using the difference in lifetimes of D-0 and (D) over bar (0) mesons, we obtain the CP-violation parameter DeltaY=[-0.8+/-0.6(stat.)+/-0.2(syst.)]%.
