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 ...
Search for charged Higgs bosons decaying into a top quark and a bottom quark at root s=13 TeV with the ATLAS detector
(Springer, 2021-06-24)
A search for charged Higgs bosons decaying into a top quark and a bottom quark is presented. The data analysed correspond to 139 fb−1 of proton-proton collisions at s√ = 13 TeV, recorded with the ATLAS detector at the LHC. ...
Search for supersymmetry in events with four or more charged leptons in 139 fb(-1) of root s=13 TeV pp collisions with the ATLAS detector
(Springer, 2021-07-22)
A search for supersymmetry in events with four or more charged leptons (electrons, muons and τ-leptons) is presented. The analysis uses a data sample corresponding to 139 fb−1 of proton-proton collisions delivered by the ...
Measurements of b-jet tagging efficiency with the ATLAS detector using t(t)over-bar events at root s=13 TeV

Search for WW/WZ resonance production in lvqq final states in pp collisions at root s=13 TeV with the ATLAS detector
(Springer, 2018-03-08)
A search is conducted for new resonances decaying into a W W or W Z boson pair, where one W boson decays leptonically and the other W or Z boson decays hadronically. It is based on proton-proton collision data with an ...
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-, ...
