The experimental signature is an energetic jet pair with invariant mass of O(1) TeVand O(100) GeVmissing transverse momentum. The analysis uses 36.1 fb(-1) of pp collision data at root s = 13 TeV recorded by the ATLAS detector at the LHC. In the signal region the 2252 observed events are consistent with the background estimation. Assuming a 125 GeV scalar particle with Standard Model cross sections, the upper limit on the branching fraction of the Higgs boson decay into invisible particles is 0.37 at 95{\%} confidence level where 0.28 was expected. This limit is interpreted in Higgs portal models to set bounds on the wimp-nucleon scattering cross section. We also consider invisible decays of additional scalar bosons with masses up to 3 TeV for which the upper limits on the cross section times branching fraction are in the range of 0.3-1.7 pb.", optnote="WOS:000470064800072", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=4045), last updated on Wed, 19 Jun 2019 12:43:19 +0000", issn="0370-2693", doi="10.1016/j.physletb.2019.04.024", opturl="https://arxiv.org/abs/1809.06682", opturl="https://doi.org/10.1016/j.physletb.2019.04.024", language="English" }
