Abstract The effective lifetime of the B0s meson in the decay B0sJ/ψK0S is measured using data collected during 2016-2018 with the CMS detector in s= 13 TeV proton-proton collisions at the LHC, corresponding to an integrated luminosity of 140 fb1. The effective lifetime is determined by performing a two-dimensional unbinned maximum likelihood fit to the B0s meson invariant mass and proper decay time distributions. The resulting value of 1.59 ± 0.07 (stat) ± 0.03 (syst) ps is the most precise measurement to date and is in good agreement with the expected value.
