DescriptionA search for pair-produced particles with masses above 100 GeV that each decay into at least four quarks is presented. The search focuses on a signal model consisting of a squark that decays into four quarks through an intermediate Higgsino with a hadronic R-parity-violating coupling. Data from proton-proton collisions with 13 TeV center-of-mass energy, collected by the Compact Muon Solenoid experiment at the Large Hadron Collider during 2015 and 2016, are analyzed for resonances in the average mass spectrum of pairs of large jets with high transverse momentum, similar mass, and substructure consistent with four partons. A novel data-driven technique is used to estimate the dominant quantum-chromodynamic multijet background events. The significant top-quark decay background events are accounted for by simulation. No statistically significant excess of observed events over expected events in the data is found. The pair production of squarks with masses between 0.10 and 0.72 TeV and gluinos with masses between 0.10 and 1.41 TeV are excluded at 95% confidence level.
