Description
We study the effects of $D^0$-$\bar{D}^0$ mixing and CP violation in $D^0 \to K^{*\pm} K^{\mp}$ decays and their CP-conjugated processes. We find that both the $D^0$-$\bar{D}^0$ mixing parameters and the strong-interaction phase difference between $\bar{D}^0 \to K^{*\pm}K^{\mp}$ and $D^0 \to K^{*\pm}K^{\mp}$ transitions can be determined from the time-dependent measurements of these decay modes. In particular, it is possible to determine these physical quantities from the time-independent measurements of coherent $(D^0\bar{D}^0) \to (K^{*\pm} K^\mp)(K^{*\pm} K^\mp)$ decays on the $\psi (3770)$ and $\psi (4140)$ resonances at a super-$\tau$-charm factory. Provided the CP-violating phase of $D^0$-$\bar{D}^0$ mixing is significant in an underlying scenario beyond the standard model, it can also be extracted from the $K^{*\pm} K^\mp$ events.
