Decays of the recently found Higgs boson into non detectable invisible-particles would be a extraordinary sign of new physics. Direct searches such decays are performed by using sub-products created together with the Higgs boson. Data taken by the ATLAS detector at center of mass energies of 7 and 8 TeV is analysed and in the absence of evidence upper limits on the branching ratio to invisible decays are set and within Higgs-portal dark matter models, limits on the dark matter-nucleon cross sections are also calculated.
