The study and search for new sources of $CP$ violation in the beauty sector provide not only a better understanding of the phenomenon itself and thus of the matter-antimatter asymmetry in the universe, but to a better understanding of the rich dynamic present in the hadronic environment. Several analyses performed by the LHCb experiment that gather new insights into $CP$ violation effects in non-leptonic $b$-hadron decays are presented in this document.
