Observation of production at 13 TeV with the ATLAS detector
ATLAS Collaboration
This paper presents the first observation of top-quark pair production in association with two photons (). The measurement is performed in the single-lepton decay cha…

Search for heavy neutral leptons in decays of W bosons produced in 13 TeV pp collisions using prompt signatures in the ATLAS detector
ATLAS Collaboration
The existence of right-handed neutrinos with Majorana masses below the electroweak scale could help address the origins of neutrino masses, the matter-antimatter asymmetry, and dar…

The performance of missing transverse momentum reconstruction and its significance with the ATLAS detector using 140 fb of TeV collisions
ATLAS Collaboration
This paper presents the reconstruction of missing transverse momentum () in proton-proton collisions, at a center-of-mass energy of 13 TeV. This is a ch…
