Short-distance matrix elements for $D^0$-meson mixing for $N_f=2+1$ lattice QCD

A. Bazavov, C. Bernard, C. M. Bouchard +17

We calculate in three-flavor lattice QCD the short-distance hadronic matrix elements of all five $\Delta C=2$ four-fermion operators that contribute to neutral $D$-meson mixing both in a…
