The data sample corresponds to an integrated luminosity of 137fb?1of proton-proton collisions at a center-of-mass energy of 13TeVcollected by the CMS experiment at the CERN LHC in 2016–2018. Candidate signal events containing nonprompt jets are identified using the timing capabilities of the CMS electromagnetic calorimeter. The results of the search are consistent with the background prediction and are interpreted using a gauge-mediated supersymmetry breaking reference model with a gluino next-to-lightest supersymmetric particle. In this model, gluino masses up to 2100, 2500, and 1900GeVare excluded at 95% confidence level for proper decay lengths of 0.3, 1, and 100m, respectively. These are the best limits to date for such massive gluinos with proper decay lengths greater than ?0.5m.enExoticaLong-lived particlesArticle10.1016/j.physletb.2019.134876Q1WOS:000488071200027Q1
