Determination of the parton distribution functions of the proton from ATLAS measurements of differential W± and Z boson production in association with jets
(Springer, 2021-07-29)
This article presents a new set of proton parton distribution functions, ATLASepWZVjet20, produced in an analysis at next-to-next-to-leading order in QCD. The new data sets considered are the measurements of W+ and W− boson ...

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 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
