Search for Heavy Neutral Leptons in Decays of W Bosons Using a Dilepton Displaced Vertex in sqrt[s]=13 TeV pp Collisions with the ATLAS Detector.
(American Physical Society, 2023-08-11)
A search for a long-lived, heavy neutral lepton (N) in 139 fb^{-1} of sqrt[s]=13 TeV pp collision data collected by the ATLAS detector at the Large Hadron Collider is reported. The N is produced via W→Nμ or W→Ne and ...

Observation of electroweak production of two jets and a Z-boson pair
(Nature Research, 2023-02)
Electroweak symmetry breaking explains the origin of the masses of elementary particles through their interactions with the Higgs field. Besides the measurements of the Higgs boson properties, the study of the scattering ...
Search for single vector-like B quark production and decay via B → bH(bb¯) in pp collisions at s = 13 TeV with the ATLAS detector
(Springer Nature, 2023)
A search is presented for single production of a vector-like B quark decaying into a Standard Model b-quark and a Standard Model Higgs boson, which decays into...
Erratum to: Search for exclusive Higgs and Z boson decays to ϕγ and ργ with the ATLAS detector (Journal of High Energy Physics, (2018), 2018, 7, (127), 10.1007/JHEP07(2018)127)
(2023-12-01)
One correction is noted for the paper. The calculation of an angle used to account for meson polarisation in the signal decays was not correct.
Observation of the γγ→ττ Process in Pb+Pb Collisions and Constraints on the τ-Lepton Anomalous Magnetic Moment with the ATLAS Detector.
(2023-10-13)
This Letter reports the observation of τ-lepton-pair production in ultraperipheral lead-lead collisions Pb+Pb→Pb(γγ→ττ)Pb and constraints on the τ-lepton anomalous magnetic moment a_{τ}. The dataset corresponds to an ...
Observation of Single-Top-Quark Production in Association with a Photon Using the ATLAS Detector.
(2023-11-03)
This Letter reports the observation of single top quarks produced together with a photon, which directly probes the electroweak coupling of the top quark. The analysis uses 139 fb^{-1} of 13 TeV proton-proton collision ...
