Study of a new kinematic weighting algorithm for the measurement of CP asymmetries in charm decays

We investigate the asymmetries that occur in charm decays at the LHCb, specifically we study $D^{\star+}\to D^0\pi^+$ and $D^{\star-}\to \bar{D}^0\pi^-$ where $D^0\to K^-K^+$ or $D^0\to \pi^-\pi^+$. We study the effect of $CP$ and detection asymmetries on MC samples generated via RapidSim and Particle Gun and implement a new kinematic weighting function which allows us to keep events that are otherwise discarded from LHCb data, since they are associated with large detection asymmetries.
