Description

We examine the sensitivity of the EMD as a measure of CP violation in three body decays. A simplified model of the $B^0 \rightarrow \pi^{+}\pi^{-}\pi^{0}$ decay is used for this test, while including the time dependent mixing effects. We use this to test the hypothesis of observable CP violation in the time dependent decay rate and find that the EMD is capable of detecting effects up to the level of $5\sigma$. We also show that in the event we have a perfect model, we can bound this sensitivity by that of the maximum likelihood ratio, as required by the Neyman Pearson lemma. Finally, we apply our testing procedure to real physics events generated by the $\texttt{Laura++}$ framework.
