Search for new non-resonant phenomena in high-mass dilepton final states with the ATLAS detector
(Springer Nature, 2020-11-04)
A search for new physics with non-resonant signals in dielectron and dimuon final states in the mass range above 2 TeV is presented. This is the first search for non-resonant signals in dilepton final states at the LHC to ...
Measurements of top-quark pair single- and double-differential cross-sections in the all-hadronic channel in pp collisions at root s=13 TeV using the ATLAS detector
(Springer, 2021-01-08)
Differential cross-sections are measured for top-quark pair production in the all-hadronic decay mode, using proton-proton collision events collected by the ATLAS experiment in which all six decay jets are separately ...
Search for flavour-changing neutral current top-quark decays t -> qZ in proton-proton collisions at root s=13 TeV with the ATLAS detector

Measurements of W+W- + >= 1 jet production cross-sections in pp collisions at root s=13 TeV with the ATLAS detector
(Springer, 2021-06-01)
Fiducial and differential cross-section measurements of W+W− production in association with at least one hadronic jet are presented. These measurements are sensitive to the properties of electroweak-boson self-interactions ...
Search for new phenomena in events with two opposite-charge leptons, jets and missing transverse momentum in pp collisions at root s=13 TeV with the ATLAS detector
(Springer, 2021-04-16)
The results of a search for direct pair production of top squarks and for dark matter in events with two opposite-charge leptons (electrons or muons), jets and missing transverse momentum are reported, using 139 fb−1 of ...
Measurements of b-jet tagging efficiency with the ATLAS detector using t(t)over-bar events at root s=13 TeV
(Springer, 2018-08-16)
The efficiency to identify jets containing b-hadrons (b-jets) is measured using a high purity sample of dileptonic top quark-antiquark pairs (𝑡𝑡⎯⎯
