For a Higgs boson with a mass of 125 GeV, assuming the Standard Model production cross section, an upper bound of 0.28 is set on the branching fraction of H → invisible at 95% confidence level, where the expected upper limit is 0.31. The results are interpreted in models of Higgs-portal dark matter where the branching fraction limit is converted into upper bounds on the dark-matter-nucleon scattering cross section as a function of the dark-matter particle mass, and compared to results from the direct dark-matter detection experiments.}, organization = {CERN for the very successful operation of the LHC}, organization = {ANPCyT, Argentina}, organization = {YerPhI, Armenia}, organization = {ARC, Australia}, organization = {BMWF, Austria}, organization = {AHAS, Azerbaijan}, organization = {SSTC, Belarus}, organization = {CNPq and FAPESP, Brazil}, organization = {NSERC, NRC and CFI, Canada}, organization = {CONICYT, Chile}, organization = {CAS, MOST and NSFC, China}, organization = {COLCIENCIAS, Colombia}, organization = {MSMT CR, MPO CR and VSC CR, Czech Republic}, organization = {DNRF, DNSRC and Lundbeck Foundation, Denmark}, organization = {ARTEMIS, European Union}, organization = {IN2P3-CNRS, CEA-DSM/IRFU, France}, organization = {GNAS, Georgia}, organization = {BMBF, DFG, HGF, MPG and AvH Foundation, Germany}, organization = {GSRT, Greece}, organization = {SF, MINERVA, GIF, DIP and Benoziyo Center, Israel}, organization = {INFN, Italy}, organization = {MEXT and JSPS, Japan}, organization = {CNRST, Morocco}, organization = {FOM and NWO, Netherlands}, organization = {RCN, Norway}, organization = {MNiSW, Poland}, organization = {GRICES and FCT, Portugal}, organization = {MERYS (MECTS), Romania}, organization = {MES of Russia and ROSATOM, Russian Federation}, organization = {JINR}, organization = {MSTD, Serbia}, organization = {MSSR, Slovakia}, organization = {ARRS and MVZT, Slovenia}, organization = {DST/NRF, South Africa}, organization = {MICINN, Spain}, organization = {SRC and Wallenberg Foundation, Sweden}, organization = {SER, SNSF and Cantons of Bern and Geneva, Switzerland}, organization = {NSC, Taiwan}, organization = {TAEK, Turkey}, organization = {FC, the Royal Society and Leverhulme Trust, United Kingdom}, organization = {DOE and NSF, United States of America}, organization = {Crucial computing support from all WLCG partners}, publisher = {Springer}, keywords = {Hadron-Hadron scattering}, keywords = {Higgs physics}, title = {Search for invisible decays of a Higgs boson using vector-boson fusion in pp collisions at √s = 8 TeV with the ATLAS detector}, doi = {0.1007/JHEP01(2016)172}, author = {Aad, G. and Aguilar Saavedra, Juan Antonio and Atlas Collaboration, /}, }
