Measurements of the inclusive and differential production cross sections of a top-quark–antiquark pair in association with a Z boson at s=13 TeV with the ATLAS detector
(Springer, 2021-08-16)
Measurements of both the inclusive and differential production cross sections of a top-quark–antiquark pair in association with a Z boson (tt¯Z) are presented. The measurements are performed by targeting final states with ...
Measurements of sensor radiation damage in the ATLAS inner detector using leakage currents
(IOP Publishing, 2021-08-01)
Non-ionizing energy loss causes bulk damage to the silicon sensors of the ATLAS pixel and strip detectors. This damage has important implications for data-taking operations, charged-particle track reconstruction, detector ...

Search for new phenomena with top quark pairs in final states with one lepton, jets, and missing transverse momentum in pp collisions at root s=13 TeV with the ATLAS detector
(Springer, 2021-04-19)
A search for new phenomena with top quark pairs in final states with one isolated electron or muon, multiple jets, and large missing transverse momentum is performed. Signal regions are designed to search for two-, three-, ...

-tagged jets, and large missing transverse momentum is presented. The analyzed dataset is based on proton-proton ...
Search for dark matter produced in association with a single top quark in root s=13 TeV pp collisions with the ATLAS detector
(Springer, 2021-10)
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 ...
Search for resonances decaying into photon pairs in 139 fb(-1) of pp collisions at root s=13 TeV with the ATLAS detector
(Elsevier, 2021-11-10)
Searches for new resonances in the diphoton final state, with spin 0 as predicted by theories with an extended Higgs sector and with spin 2 using a warped extra-dimension benchmark model, are presented using 139 fb−1 of ...
Search for New Phenomena in Final States with Two Leptons and One or No b-Tagged Jets at s=13 TeV Using the ATLAS Detector
(American Physical Society, 2021-10-01)
A search for new phenomena is presented in final states with two leptons and one or no
b
-tagged jets. The event selection requires the two leptons to have opposite charge, the same flavor (electrons or muons), and a ...
Search for dark matter in events with missing transverse momentum and a Higgs boson decaying into two photons in pp collisions at root s=13 TeV with the ATLAS detector
(Springer, 2021-10-01)
A search for dark-matter particles in events with large missing transverse momentum and a Higgs boson candidate decaying into two photons is reported. The search uses 139 fb−1 of proton-proton collision data collected at ...
