Search for CPV in Charm

After the discovery of CP violation in decays containing a quark charm with the observation of the difference between 𝐴𝐶𝑃(𝐾−𝐾+) and 𝐴𝐶𝑃(𝜋−𝜋+), it is not clear the nature of the violation and the size of the violation in each of the two decays. A search for the individual CP asymmetries 𝐴𝐶𝑃(ℎ−ℎ+) is performed at the LHCb detector using proton-proton collisions recorded in Run 2
