Search for third-generation vector-like leptons in pp collisions at √s = 13 TeV with the ATLAS detector
(Springer, 2023-07-14)
A search for vector-like leptons in multilepton (two, three, or four-or-more electrons plus muons) final states with zero or more hadronic τ-lepton decays is presented. The search is performed using a dataset corresponding ...
Determination of the strong coupling constant from transverse energy-energy correlations in multijet events at √s = 13 TeV with the ATLAS detector
(Springer, 2023-07-11)
Measurements of transverse energy-energy correlations and their associated azimuthal asymmetries in multijet events are presented. The analysis is performed using a data sample corresponding to 139 fb −1 of proton-proton ...
Search for leptonic charge asymmetry in tt¯ W production in final states with three leptons at √s = 13 TeV
(Springer, 2023-07-05)
A search for the leptonic charge asymmetry (Acℓ) of top-quark-antiquark pair production in association with a W boson (tt¯ W) is presented. The search is performed using final states with exactly three charged light leptons ...
Measurement of the properties of Higgs boson production at √s = 13 TeV in the H → γγ channel using 139 fb<sup>−1</sup> of pp collision data with the ATLAS experiment
(Springer Nature, 2023-07-11)
Measurements of Higgs boson production cross-sections are carried out in the diphoton decay channel using 139 fb−1 of pp collision data at s = 13 TeV collected by the ATLAS experiment at the LHC. The analysis is based on ...
Search for dark matter produced in association with a dark Higgs boson decaying into W<sup>+</sup> W<sup>−</sup> in the one-lepton final state at √s = 13 TeV using 139 fb<sup> −1</sup> of pp collisions recorded with the ATLAS detector
(Springer, 2023-07-13)
Several extensions of the Standard Model predict the production of dark matter particles at the LHC. A search for dark matter particles produced in association with a dark Higgs boson decaying into W+ W− in the ℓ±νqq¯′, ...
Search for flavour-changing neutral current interactions of the top quark and the Higgs boson in events with a pair of τ-leptons in pp collisions at √s = 13 TeV with the ATLAS detector
(2023-06-01)
A search for flavour-changing neutral current (FCNC) tqH interactions involving a top quark, another up-type quark (q = u, c), and a Standard Model (SM) Higgs boson decaying into a τ-lepton pair (H → τ + τ −) is presented. ...
Exclusive dielectron production in ultraperipheral Pb+Pb collisions at √sNN = 5.02 TeV with ATLAS
(2023-07-01)
Exclusive production of dielectron pairs, γγ → e + e −, is studied using Lint = 1.72 nb−1 of data from ultraperipheral collisions of lead nuclei at sNN = 5.02 TeV recorded by the ATLAS detector at the LHC. The process of ...
Search for excited τ-leptons and leptoquarks in the final state with τ-leptons and jets in pp collisions at √s = 13 TeV with the ATLAS detector
(2023-07-01)
A search is reported for excited τ-leptons and leptoquarks in events with two hadronically decaying τ-leptons and two or more jets. The search uses proton-proton (pp) collision data at s = 13 TeV recorded by the ATLAS ...
