Measurement of the -boson angular coefficients and transverse momentum in collisions at 13 TeV with the ATLAS detector
The ATLAS Collaboration
The angular distributions of Drell-Yan lepton pairs provide sensitive probes of the underlying dynamics of quantum chromodynamics (QCD) effects in vector-boson production. This pap…

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…

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…
