ATLAS was one of the two LHC experiments involved in the discovery of the [[Higgs boson]] in July 2012.<ref name="Higgs2012">{{cite web|url=http://press.cern/press-releases/2012/07/cern-experiments-observe-particle-consistent-long-sought-higgs-boson|title=CERN experiments observe particle consistent with long-sought Higgs boson|date=4 July 2012|publisher=[[CERN]]|access-date=2016-11-23}}</ref><ref name="Higgs2013">{{cite web|url=http://press.cern/backgrounders/cern-and-higgs-boson|title=CERN and the Higgs boson|publisher=CERN|access-date=23 November 2016|archive-url=https://web.archive.org/web/20161123201553/http://press.cern/backgrounders/cern-and-higgs-boson|archive-date=23 November 2016|url-status=dead}}</ref> It was also designed to search for evidence of [[theories]] of [[particle physics]] beyond the [[Standard Model]].

The experiment is a collaboration involving 6,003 members, out of which 3,822 are [[physicist]]s (last update: June 26, 2022) from 243 institutions in 40 countries.<ref name=fact_sheets/><ref name=collaboration>{{cite web |title=The Collaboration |url= https://atlas.cern/discover/collaboration |publisher= ATLAS |access-date=15 March 2025}}</ref>
