| Summary: | 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 clustered into two large
jets of similar mass, each consistent with four-parton substructure. No statistically significant excess of data
over the background prediction is observed in the distribution of average jet mass. Pair-produced squarks
with dominant hadronic R-parity-violating decays into four quarks and with masses between 0.10 and
0.72 TeV are excluded at 95% confidence level. Similarly, pair-produced gluinos that decay into five quarks
are also excluded with masses between 0.10 and 1.41 TeV at 95% confidence level. These are the first
constraints that have been placed on pair-produced particles with masses below 400 GeV that decay into
four or five quarks, bridging a significant gap in the coverage of R-parity-violating supersymmetry
parameter space. |
