abstract = {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 transversemomentum are considered. The
analysis is based on proton–proton collision data collected
with the ATLAS experiment at
√
s = 13 TeV during LHC
Run 2 (2015–2018), corresponding to an integrated luminosity
of 139 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.},
