This signature is expected in some extensions of the Standard Model predicting the production of dark matter particles, and is interpreted in terms of a dark Higgs model containing a $Z'$ mediator in which the dark Higgs boson $s$ decays into a pair of Higgs bosons. The dark Higgs boson is reconstructed through final states with at least three $b$-tagged jets, produced by the pair of Higgs boson decays, in events with significant missing transverse momentum consistent with the presence of dark matter. The observed data are found to be in good agreement with Standard Model predictions, constraining scenarios with dark Higgs boson masses within the range of 250 to 400 GeV and $Z'$ mediators up to 2.3 TeV.}, cin = {ATLAS}, cid = {I:(DE-H253)ATLAS-20120731}, pnm = {611 - Fundamental Particles and Forces (POF4-611) / DFG project G:(GEPRIS)469666862 - Präzisionstests des Standardmodells unter der Verwendung von geboosteten W/Z-Bosonen am Large Hadron Collider (469666862) / BARD - B-resonance Algorithm using Rare Decays (101116429) / DITTO - Comprehensive search for new phenomena in the dilepton spectrum at the LHC (101089007) / REALDARK - REAL-time discovery strategies for DARK matter and dark sector signals at the ATLAS detector with Run-3 LHC data (101002463) / SMASH - Machine learning for Sciences and Humanities (101081355)}, pid = {G:(DE-HGF)POF4-611 / G:(GEPRIS)469666862 / G:(EU-Grant)101116429 / G:(EU-Grant)101089007 / G:(EU-Grant)101002463 / G:(EU-Grant)101081355}, experiment = {EXP:(DE-H253)LHC-Exp-ATLAS-20150101}, typ = {PUB:(DE-HGF)25}, eprint = {2507.02175}, howpublished = {arXiv:2507.02175}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:2507.02175;\%\%$}, doi = {10.3204/PUBDB-2025-02554}, url = {https://bib-pubdb1.desy.de/record/634640}, }
