Abstract (data abstract)
A search for dark matter produced in association with a dark Higgs boson, s, decaying into $W^\pm W^\mp$ or $ZZ$ in fully hadronic final states from center-of-mass energy of $\sqrt{s}=$13 TeV pp collisions recorded with the ATLAS detector between 2015 and 2018, corresponding to an integrated luminosity of 139 fb$^{-1}$. The $s\to V(q\bar q)V(q\bar q)$ 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.
