This search uses 36.1 fb(-1) of data collected by the ATLAS experiment at the Large Hadron Collider. No significant deviation from the expectation of the Standard Model backgrounds is observed. Assuming the Standard Model ZH production cross-section, an observed (expected) upper limit of 67{\%} (39{\%}) at the 95{\%} confidence level is set on the branching ratio of invisible decays of the Higgs boson with mass m(H) = 125 GeV. The corresponding limits on the production cross-section of the ZH process with the invisible Higgs boson decays are also presented. Furthermore, exclusion limits on the dark matter candidate and mediator masses are reported in the framework of simplified dark matter models.", optnote="WOS:000419641100044", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3460), last updated on Tue, 06 Feb 2018 16:11:36 +0000", issn="0370-2693", doi="10.1016/j.physletb.2017.11.049", opturl="http://arxiv.org/abs/1708.09624", opturl="https://doi.org/10.1016/j.physletb.2017.11.049", archivePrefix="arXiv", eprint="1708.09624", language="English" }
