Le résumé fourni par la source

We have searched for mixing in the D 0 -D 0 system by measuring the decay-time distribution of D 0 !K ÿ decays.The analysis uses 90 fb ÿ1 of data collected by the Belle detector at the KEKB e e ÿ collider.We fit the decay-time distribution for the mixing parameters x 0 and y 0 and also for the parameter R D , which is the ratio of the rate for the doubly-Cabibbo-suppressed decay D 0 !K ÿ to that for the Cabibbo-favored decay D 0 !K ÿ .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 02 -y 0 plane.Assuming no mixing, we measure R D 0:381 0:017 0:008 ÿ0:016 %.
