Abstract

We report an improved measurement of D-0-(D) over bar (0) mixing and a search for CP violation in D-0 decays to CP-even final states K+K- and pi(+)pi(-). The measurement is based on the final Belle data sample of 976 fb(-1). The results are y(CP) = (1.11 +/- 0.22 +/- 0.09)% and A(Gamma) =(-0.03 +/- 0.20 +/- 0.07)%, where the first uncertainty is statistical and the second is systematic. (C) 2015 The Authors.
