A Review of CP Violation Measurements in Charm at LHCb

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 D0→Ks0Ks0, D(s)+→h+π0 and D(s)+→h+η decays are summarised, in addition to the most precise measurement of time-dependent CP asymmetry in D0→h+h− decays and the first observation of mass difference between neutral charm-meson eigenstates.

Study of the D-mixing parameter y in the factorization-assisted topological-amplitude approach

The contributions to the D0 − $ \bar {D}^0 $ mixing parameter y from the D0 → PP, PV channels are calculated, based on the corresponding decay amplitudes extracted from data in the factorization-assisted topological-amplitude approach. It is found that the PP, PV contributions amount up to yPP+PV = (0.21 ± 0.07), about one third of the experiment measurement yexp = (0.63 ± 0.08)%.
