    • Abstract

       

      The Standard Model (SM) and new physics (NP) descriptions of $D^{0}$ mixing are discussed. The SM part of the discussion addresses both quark-level and hadron-level contributions. The NP part describes our recent works on the rate difference $\Delta \Gamma_{D}$ and the mass difference $\Delta M_{\text{D}}$. In particular, we describe how the recent experimental determination of $\Delta M_{\text{D}}$ is found to place tightened restrictions on parameter spaces for 17 out of the 21 NP models considered.
