Content
We present our final results for the neutral $D$-meson mixing matrix elements of the complete set of dimension six $\Delta C=2$ local four-fermion operators from the first three-flavor lattice QCD calculation. We use a large subset of the MILC asqtad ensembles together with Fermilab charm and asqtad light valence quarks. We provide complete and detailed systematic error budgets which account for all sources of uncertainty. The correlations between the $D$-mixing matrix elements are also reported. Our matrix element results provide useful constraints on certain BSM theories, when combined with the corresponding experimental averages, which we illustrate in a few examples.
