Search for long-lived particles with displaced vertices in multijet events in proton-proton collisions at s =13 TeV

Results are reported from a search for long-lived particles in proton-proton collisions at ffiffi s p ¼ 13 TeV delivered by the CERN LHC and collected by the CMS experiment. The data sample, which was recorded during 2015 and 2016, corresponds to an integrated luminosity of 38.5 fb−1. This search...
