Description

The difference between the $C P$ asymmetries in $\mathrm{D}^0 \rightarrow \mathrm{K}_{\mathrm{S}}^0 \mathrm{~K}_{\mathrm{S}}^0$ and $\mathrm{D}^0 \rightarrow \mathrm{K}_{\mathrm{S}}^0 \pi^{+} \pi^{-}$ decays is measured to be $\Delta A_{C P}=(\it{xx.xx} \pm 3.1) \%$. The analysis is performed on the parked data of pp collisions, which were collected by the CMS experiment in 2018 at $\sqrt{s}=$ $13 \mathrm{TeV}$ with a dedicated delayed data processing stream allowing to record more than $10^{10}$ events.
