N2 - A measurement of time-dependent CP violation in the decays of B0 and ¯B0 mesons to the final states J/ψ(→μ+μ−)K0S, ψ(2S)(→μ+μ−)K0S and J/ψ(→e+e−)K0S with K0S→π+π− is presented. The data correspond to an integrated luminosity of 6 fb−1 collected at a center-of-mass energy of √s=13 TeV with the LHCb detector. The CP-violation parameters are measured to be SψK0S=0.717±0.013(stat)±0.008(syst) and CψK0S=0.008±0.012(stat)±0.003(syst). This measurement of SψK0S represents the most precise single measurement of the CKM angle β to date and is more precise than the current world average. In addition, measurements of the CP-violation parameters of the individual channels are reported and a combination with the LHCb Run 1 measurements is performed.
