CPViolation inD0-D¯0Mixing

The existence of $D^0$- ${\overline{D}}^0$ mixing at a detectable level requires new physics, which effectively yields a $\Delta c=2\mathrm{}$ superweak interaction. In general this interaction may involve significant $\mathrm{CP}$ violation. For small values of the mixing it may be much easier to detect the $\mathrm{CP}$-violating part of the mixing than the $\mathrm{CP}$-conserving part.
