Description
There is experimental evidence for a direct CP asymmetry in singly Cabibbo suppressed $D$ decays, $\Delta A_{CP}$ of order a percent. Naive expectations are that the Standard Model contribution to $\Delta A_{CP}$ is an order of magnitude smaller. We explore the possibility that a major part of the asymmetry comes from new physics. In this context we discuss accommodating this large contribution to CP violation in charm decays in both a minimal model with an extra scalar doublet,previously suggested to explain the large forward-backward asymmetry in $t\bar t$ production at the Tevatron, as well as in supersymmetric flavor models.
