Searches for dark matter with the ATLAS detector

Despite several observational evidence for dark matter, there is no experimental hint on its nature so far. As a result, a plethora of scenarios extending the standard model of particle physics can accomodate dark matter-related observations while escaping the latest experimental constraints. In this context, one of the main approaches pursued by the ATLAS collaboration at the LHC is to search for weakly-interating massive particles with minimal assumptions, which we give a brief overview in this document.
