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 ...
Anomaly detection search for new resonances decaying into a Higgs boson and a generic new particle X in hadronic final states using s=13 TeV pp collisions with the ATLAS detector

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...
Tools for estimating fake/non-prompt lepton backgrounds with the ATLAS detector at the LHC
(IOP Publishing, 2023-11-01)
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 ...
