摘　　要：Results from a wide range of searches targeting different experimental signatures with and without missing transverse momentum(E_(T)^(miss))are used to constrain a Two-Higgs-Doublet Model(2HDM)with an additional pseudo-scalar mediating the interaction between ordinary and dark matter(2HDM+a).The analyses use up to 139 fb^(-1)of proton–proton collision data at a centre-of-mass energy√s=13 TeV pp recorded with the ATLAS detector at the Large Hadron Collider during 2015–2018.The results from three of the most sensitive searches are combined statistically.These searches target signatures with large E_(T)^(miss)and a leptonically decaying Z boson;large E_(T)^(miss)and a Higgs boson decaying to bottom quarks;and production of charged Higgs bosons in final states with top and bottom quarks,respectively.Constraints are derived for several common and new benchmark scenarios in the 2HDM+a.
