Description

Various extensions of Standard Model predict possible decays to invisible particles of the Higgs boson recently discovered at the Large Hadron Collider. This presentation will report results of a direct search for invisible decays of Standard Model-like Higgs boson which is produced in association with a Z boson, using the 4.7 fb-1 of data at sqrt(s) = 7TeV and 20.3fb-1 of data at sqrt(S) = 8 TeV recorded by the ATLAS detector. This contribution will report ATLAS limits on the branching fraction for the Higgs boson decays to invisible particles at m_{H} = 125 GeV. Limits will be also presented for the cross section times the branching fraction of a possible additional Higgs-like boson decaying to invisible particles over the mass range 115 GeV < mH < 300 GeV.
