Abstract / Description of output

A measurement of charm mixing and CP-violating parameters is reported, using ¯B→D0(→K0Sπ+π−)μ−¯νμX 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 xCP=[4.29±1.48(stat)±0.26(syst)]×10−3, yCP=[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(→K0Sπ+π−)π+ decays is reported.
