摘要：
While the CKM paradigm of CP violation has been tested extensively in K and B mesons, CP violation remains unobserved in the decay of up-type quarks. The study of CP violation in charm decays is thus a complementary test of the Standard Model, since it allows constraining CP-violating operators that might leave the observables of down-type quarks unaffected. Two recent measurements of CP violation in charm decays by the LHCb Collaboration are reviewed. Their precision, below the 10(-3) level, is finally entering the upper limit of the range of Standard Model predictions. The forthcoming Upgrade I of LHCb (2021-2029) will allow pushing the precision of the searches for CP violation in charm below the 10(-4) level.
