The crucial computing support from all WLCG partners is ac-knowledged gratefully, in particular from CERN, the ATLAS Tier-1 facilities at TRIUMF (Canada), NDGF (Denmark, Norway, Sweden), CC-IN2P3 (France), KIT/GridKA (Germany), INFN-CNAF (Italy), NL-T1 (Netherlands), PIC (Spain), ASGC (Taiwan), RAL (UK) and BNL (USA), the Tier-2 facilities worldwide and large non-WLCG resource providers. Major contributors of computing resources are listed in Ref.[109].es_ES
dc.description.abstractA search for invisible decays of the Higgs boson as well as searches for dark matter candidates, produced together with a leptonically decaying Zboson, are presented. The analysis is performed using proton−proton collisions at a centre-of-mass energy of 13TeV, delivered by the LHC, corresponding to an integrated luminosity of 139fb−1and recorded by the ATLAS experiment. Assuming Standard Model cross-sections for ZHproduction, the observed (expected) upper limit on the branching ratio of the Higgs boson to invisible particles is found to be 19% (19%) at the 95% confidence level. Exclusion limits are also set for simplified dark matter models and two-Higgs-doublet models with an additional pseudoscalar mediator.es_ES
