Abstract
Dark matter particles, if sufficiently light, may be produced in decays of the Higgs boson. This Letter presents a statistical combination of searches for decays where is produced according to the standard model via vector boson fusion, , and , all performed with the ATLAS detector using of collisions at a center-of-mass energy of at the LHC. In combination with the results at and 8 TeV, an exclusion limit on the branching ratio of at 95% confidence level is observed (expected).
