An uncharted signature of dark matter particles produced in association with VV = (WW -/+)-W-+/- or ZZ pairs from a decay of a dark Higgs boson s is searched for using 139 fb(-1) of pp collisions recorded by the ATLAS detector at a center-of-mass energy of 13 TeV. The s -> V(q (q) over bar )V(q (q) over bar) decays are reconstructed with a novel technique aimed at resolving the dense topology from boosted VV pairs using jets in the calorimeter and tracking information. Dark Higgs scenarios with m(s) > 160 GeV are excluded.eninfo:eu-repo/semantics/openAccessBroken SymmetriesPair ProductionGaugeSearch for Dark Matter Produced in Association with a Dark Higgs Boson Decaying into W±W? or ZZ in Fully Hadronic Final States from ?s=13 TeV pp Collisions Recorded with the ATLAS DetectorArticle2-s2.0-8510351716810.1103/PhysRevLett.126.1218021233834820Q1126Q1WOS:000646119900006
