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

Abstract

Here, we report an improved measurement of D0–$$\bar{D}$$0 mixing and a search for CP violation in D0 decays to CP -even final states K+K and 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)% and AΓ = (–0.03 ± 0.20 ± 0.07)%, where the first uncertainty is statistical and the second is systematic.
