Abstract

We report the results of a search for D0-D̄0 mixing in D0→K+π- decays based on 400fb-1 of data accumulated by the Belle detector at KEKB. Both assuming CP conservation and allowing for CP violation, we fit the decay-time distribution for the mixing parameters x′ and y′, as well as for the parameter RD, the ratio of doubly Cabibbo-suppressed decays to Cabibbo-favored decays. The 95% confidence level region in the (x′2,y′) plane is obtained using a frequentist method. Assuming CP conservation, we find x′2
