【 摘 要 】

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 $𝛥 𝛤_{D}$ and the mass difference 𝛥 𝑀D. In particular, we describe how the recent experimental determination of 𝛥 𝑀D is found to place tightened restrictions on parameter spaces for 17 out of the 21 NP models considered.
