Abstract: 

This is the second half of the seminar due to be presented on the 15th November that was rudely interrupted by a fire alarm.

CP violation in meson systems provides insights into the flavour changing structure of the standard model and might help to improve our understanding of the Universe on a large scale providing a candidate mechanism to explain the observed matter-antimatter asymmetry. After reviewing the general methods and results of CP violation searches in the charm system, I describe how a time-dependent analysis can be used to measure T and CP asymmetries and how the latter translates into constraints on the mixing phase and on the parameter \beta_{c,eff} (in the charm unitarity triangle). Finally I show the results of a simulated study on the sensitivity achievable on \beta_{c,eff} in an asymmetric tau-charm factory with a luminosity of 2x10^35 cm^-2 s^-1,  when looking for time-dependent CP asymmetries in D0 -> h+h-.
