| Abstract: A search for a displaced dark matter candidate produced in association with a 4-prong boosted large-radius jet is presented. The analysis is based on data collected in the years 2016--2018 with the CMS detector at the LHC in proton-proton collisions at $ \sqrt{s}= $ 13 TeV, corresponding to an integrated luminosity of 138 fb$ ^{-1} $. Signal candidates are reconstructed as large-radius jets and identified using a graph-neural-network-based jet substructure tagger. The standard model background contributions are estimated from the data using dedicated control regions. The missing transverse momentum spectrum is probed for a potential signal over the expected background. No significant excess over the standard model expectation is observed and upper limits at the 95% confidence level are set on the signal strength as a function of the mediator mass and the coupling between the dark matter particles and the scalar mediator. | ||
