Search for pair-produced resonances each decaying into at least four quarks in proton-proton collisions at s =13 TeV

This Letter presents the results of a search for pair-produced particles of masses above 100 GeV that each decay into at least four quarks. Using data collected by the CMS experiment at the LHC in 2015–2016, corresponding to an integrated luminosity of 38.2 fb−1, reconstructed particles are cluste...
