Description
A search for CP violation in the charm sector is performed through a full amplitude analysis of the decay mode $D^0 \rightarrow K^+ K^- \pi^+ \pi^-$. Its complicated resonant structure and the interferences between the various amplitudes together with the unprecedented statistic may offer the opportunity to observe CP violation for the first time in charm mesons. This symmetry breaking is expected to be small in the standard model, which makes effect of physics beyond the Standard Model comparable, if not bigger. One of the key points of the analysis is to develop an amplitude model that describes with good approximation the five dimensional phase space of the data.
