Search for invisible decay modes of the Higgs boson with the ATLAS detector

The Higgs boson provides a unique way to probe the production of Dark Matter particles in the proton-proton collisions at the Large Hadron Collider, through searches for its decay into invisible particles. With the data sample collected at the centre-of-mass energy of 8 TeV the ATLAS Collaboration has performed searches in a number of production modes of the Higgs boson. The results are compatible with the Standard Model expectations and they have been used to set upper limits on the branching ratio for the Higgs decay into invisible particles. A first result obtained with data collected at the new energy regime of 13 TeV in the $ZH,\,Z\rightarrow \ell\ell$ $H\rightarrow$ \textit{invisible} channel has also been presented.
