摘要：

We measure the time dependence of the ratio of decay rates for the rare decay D-0 -> K+pi(-) to the Cabibbo-favored decay D-0 -> K-pi(+). A signal of 12.7x10(3) D-0 -> K+pi(-) decays was obtained using the Collider Detector at Fermilab II detector at the Fermilab Tevatron with an integrated luminosity of 1.5 fb(-1). We measure the D-0-(D) over bar (0) mixing parameters (R-D,y('),x('2)), and find that the data are inconsistent with the no-mixing hypothesis with a probability equivalent to 3.8 Gaussian standard deviations.
