Sumario:The existence of CP violation in the decays of strange and beauty mesons is very well established experimentally. On the contrary, CP violation in the decays of charmed particles has never been observed before (2018). During the LHC Run I and Run II the LHCb collaboration has collected a huge sample of charmed hadrons. This sample enables some of the most sensitive searches for CP violation ever performed. In this presentation, the results of the latest search for time-integrated CP violation in D0→K−K+ and D0→π−π+ decays, performed using the full data set collected by LHCb corresponding to an integrated luminosity of 9fb−1, will be discussed. The flavour of the decaying charm meson is determined by looking at the charge of the pion from the strong decay D∗(2010)+→D0π+ for promptly produced D0, or at the charge of the muon in semileptonic B0¯,B−→D0μ−ν¯μX decays for secondary production of D0. Also a brief prospects for further analyses (especially including Ξc barion decay) will be presented.
