摘要We have searched for mixing in the Ddegrees-(D) over cap (0) D-0 system by measuring the decay-time distribution of D0 ! K(+)pi(-) decays. The analysis uses 90 fb(-1) of data collected by the Belle detector at the KEKB e(+) e(-) collider. We fit the decay-time distribution for the mixing parameters x(1) and y(1) and also for the parameter R-D, which is the ratio of the rate for the doubly-Cabibbo-suppressed decay D-0--> K(+)pi(-) to that for the Cabibbo-favored decay D-0 --> K- pi(+). We do these fits both assuming CP conservation and allowing for CP violation. We use a frequentist method to obtain a 95% C. L. region in the x(J2)- y(l) plane. Assuming no mixing, we measure R-D=(0: 381 +/- 0: 017 (+) (0.008)(-0.016))%.
