  "abstract": "<p>This paper presents a search for dark matter in the context of a two-Higgs-doublet model together with an additional pseudoscalar mediator, a, which decays into the dark-matter particles. Processes where the pseudoscalar mediator is produced in association with a single top quark in the 2HDM+a model are explored for the first time at the LHC. Several final states which include either one or two charged leptons (electrons or muons) and a significant amount of missing transverse momentum are considered. The analysis is based on proton\u2013proton collision data collected with the ATLAS experiment at     $\\sqrt{s}=13$   TeV during LHC Run 2 (2015\u20132018), corresponding to an integrated luminosity of 139     ${\\text{fb}}^{-1}$  . No significant excess above the Standard Model predictions is found. The results are expressed as 95% confidence-level limits on the parameters of the signal models considered.</p>",
