dc.description.abstractThe effective lifetime of the B0 s meson in the decay B0 s - J/uK0 S is measured using data collected during 2016-2018 with the CMS detector in vs = 13TeV proton-proton collisions at the LHC, corresponding to an integrated luminosity of 140fb-1. The effective lifetime is determined by performing a two-dimensional unbinned maximum likelihood fit to the B0 s 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.es_ES
dc.description.sponsorshipWe congratulate our colleagues in the CERN accelerator departments for the excellent performance of the LHC and thank the technical and administrative stafs at CERN and at other CMS institutes for their contributions to the success of the CMS efort. In addition, we gratefully acknowledge the computing centers and personnel of the Worldwide LHC Computing Grid and other centers for delivering so efectively the computing infrastructure essential to our analyses.
