LHCb search for time-integrated CP-violation in DºK-K+,π-π+ decays

LHCb has measured, ΔACP, the difference between the time-integrated CP asymmetries in the decays D0K-K+ and D0π-π+ and obtained a preliminary result of ΔACP = -0.82 ± 0.21 (stat) ± 0.11 (syst) %. This is the most precise search for CP violation in singly Cabibbo suppressed charm decays, and is the first evidence of CP violation in the charm system
