   Sammanfattning : This thesis presents a search for dark matter with the ATLAS experiment using 139 fb−1 of pp collision data at √s = 13 TeV delivered by the LHC from 2015 to 2018. The search targets a simplified model where a spin-0 scalar or pseudoscalar mediator particle, decaying to a pair of dark matter particles, is produced in association with a pair of top quarks.
