Abstract

A measurement of charm mixing and CP-violating parameters is reported, using anti-B → D0(→ K0S π+ π−) μ− anti-ν_μ X decays reconstructed in proton-proton collisions collected by the LHCb experiment during the years 2016 to 2018, corresponding to an integrated luminosity of 5.4 fb^−1. The measured mixing and CP-violating parameters are x_CP = [4.29 ± 1.48(stat) ± 0.26(syst)] × 10^−3, y_CP = [12.61 ± 3.12(stat) ± 0.83(syst)] × 10^−3, Δx = [−0.77 ± 0.93(stat) ± 0.28(syst)] × 10^−3, Δy = [3.01 ± 1.92(stat) ± 0.26(syst)] × 10^−3. The results are complementary to and consistent with previous measurements. A combination with the recent LHCb analysis of D*+ → D0(→ K0S π+ π−) π+ decays is reported.
