Abstract

Several extensions of the Standard Model predict the production of dark matter particlesat the LHC. An uncharted signature of dark matter particles produced in association with ±W  or ZZ pairs from a decay of a dark Higgs boson s is searched for using 139 fb−1of pp collisions recorded by the ATLAS detector at a center-of-mass energy of 13 TeV. The sV(qq̅)V(qq̅) 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 ms > 160 GeV are excluded.
