A Review of $CP$ Violation Measurements in Charm at LHCb

Abstract

The LHCb experiment has been able to collect the largest sample ever produced of charm-hadron decays, performing a number of measurements of observables related to $CP$ violation in the charm sector. In this document, the most recent results from LHCb on the search of direct $CP$ violation in $D^0\to K_s^0{K}_s^0$, $D_{(s)}^{+}\to h^{+}{\pi }^0$ and $D_{(s)}^{+}\to h^{+}\eta$ decays are summarised, in addition to the most precise measurement of time-dependent $CP$ asymmetry in $D^0\to h^{+}{h}^{-}$ decays and the first observation of mass difference between neutral charm-meson eigenstates.
