Search for Dark Matter with 2HDM+a in pp Collisions at \(\sqrt {s}\) = 13 TeV with the ATLAS Detector
摘要
Results obtained from various searches with and without missing transverse energy are used to constrain a Two-Higgs-Doublet Model with an additional pseudo-scalar. The analysis utilizes data from proton-proton collisions recorded with the ATLAS experiment at the LHC during 2015 and 2018 at a center-of-mass energy of \(\sqrt {s} = 13\) TeV, corresponding to an integrated luminosity of 139 \(\text{fb}^{-1}\) . This paper highlights the results from the statistical combination of three highly sensitive searches.
