Description
The results of the first study of CP violation in the charm sector at the CMS experiment are presented. The analysis is based on the proton-proton collision data with the center-of-mass energy of $\sqrt{s} = 13$ TeV. The measured CP violation parameter is $A_{CP} (D^{0} \to K^{0}_{S}K^{0}_{S}) = (6.2 \pm 3.1(\text{stat.}) \pm 0.2(\text{syst.})\pm 0.8(A_{CP} (D^{0} \to K^{0}_{S}\pi^{+}\pi^{-})) \%$, where the last uncertainty is due to the uncertainty in the reference channel asymmetry $A_{CP} (D^{0} \to K^{0}_{S}\pi^{+}\pi^{-})$. Further searches for charm CP violation with novel RUN 3 data and new refined analysis techniques are in progress.
