Measurement of D0–D‾0 mixing and search for CP violation in D0 → K+K−,π+π− decays with the full Belle data set

We report an improved measurement of D0D0–D‾0 mixing and a search for CP   violation in D0D0 decays to CP  -even final states K+K−K+K− and π+π−π+π−. The measurement is based on the final Belle data sample of 976 fb−1. The results are yCP=(1.11±0.22±0.09)%yCP=(1.11±0.22±0.09)% and AΓ=(−0.03±0.20±0.07)%AΓ=(−0.03±0.20±0.07)%, where the first uncertainty is statistical and the second is systematic.
