Title: Observation of D 0 - D ¯ 0 Mixing in e + e - Collisions

Abstract

In this work, we observe D 0 - D ¯ 0 mixing in the decay D0K+π- using a data sample of integrated luminosity 976 fb - 1 collected with the Belle detector at the KEKB e+e- asymmetric-energy collider. We measure the mixing parameters x ' 2 = ( 0.09 ± 0.22 ) × 1 0 - 3 and y ' = ( 4.6 ± 3.4 ) × 1 0 - 3 and the ratio of doubly Cabibbo-suppressed to Cabibbo-favored decay rates R D =(3.53±0.13)×10 - 3 , where the uncertainties are statistical and systematic combined. Our measurement excludes the no-mixing hypothesis at the 5.1 standard deviation level.
