Summary of WG7 at CKM 2018: "Mixing and $CP$ violation in the $D$ system: $x_D$, $y_D$, $\mathrm{\mid }q\mathrm{/}p{\mathrm{\mid }}_D$, ${\varphi }_D$, and direct $CP$ violation in $D$ decays"

The “10${}^{\mathrm{t}\mathrm{h}}$ International Workshop on the CKM Unitary Triangle” took place at the University of Heidelberg on September 17${}^{\mathrm{t}\mathrm{h}}$-21${}^{\mathrm{s}\mathrm{t}}$, 2018. In this write-up, we summarize the material discussed at the workshop by the Working Group 7, which focused on latest experimental results and theoretical developments in the study of mixing and $CP$ violation in the neutral $D$ system, and of $CP$ violation and decay properties of other charm mesons and baryons.
