Description

Current experiments measuring CP asymmetries in $D$ meson decays approach a sensitivity which is comparable to the tiny Standard-Model (SM) predictions for these quantities. However, the errors of the SM predictions, which essentially all rely on the approximate SU(3) flavour symmetry, make the search for new physics in $D$-meson CP asymmetries difficult. I present new calculations which control the dominant hadronic uncertainties up to linear order in SU(3) breaking. I further discuss the potentially large CP asymmetry in $D^0\to K_S{K}_S$.
