Search for flavor-changing neutral-current couplings between the top quark and the Z boson with proton-proton collisions at s=13 TeV with the ATLAS detector
(American Physical Society (APS), 2023-08-01)
Search for the charged-lepton-flavor-violating decay Z→eμ in pp collisions at s=13 TeV with the ATLAS detector
(American Physical Society (APS), 2023-08-01)
Inclusive and differential cross-sections for dilepton tt¯ production measured in √s = 13 TeV pp collisions with the ATLAS detector
(Springer Nature, 2023-07-01)
Differential and double-differential distributions of kinematic variables of leptons from decays of top-quark pairs (tt¯) are measured using the full LHC Run 2 data sample collected with the ATLAS detector. The data were ...
Search for boosted diphoton resonances in the 10 to 70 GeV mass range using 138 fb<sup> −1</sup> of 13 TeV pp collisions with the ATLAS detector
(Springer Nature, 2023-07-01)
A search for diphoton resonances in the mass range between 10 and 70 GeV with the ATLAS experiment at the Large Hadron Collider (LHC) is presented. The analysis is based on pp collision data corresponding to an integrated ...
Search for tt¯ H/ A→ tt¯ tt¯ production in the multilepton final state in proton–proton collisions at √s = 13 TeV with the ATLAS detector
(Springer Nature, 2023-07-01)
A search for a new heavy scalar or pseudo-scalar Higgs boson (H/A) produced in association with a pair of top quarks, with the Higgs boson decaying into a pair of top quarks (H/A → tt¯) is reported. The search targets a ...
Search for new phenomena in multi-body invariant masses in events with at least one isolated lepton and two jets using √s = 13 TeV proton–proton collision data collected by the ATLAS detector
(Springer Nature, 2023-07-01)
A search for resonances in events with at least one isolated lepton (e or μ) and two jets is performed using 139 fb −1 of s = 13 TeV proton–proton collision data recorded by the ATLAS detector at the LHC. Deviations from ...
ATLAS flavour-tagging algorithms for the LHC Run 2 pp collision dataset
(Springer Nature, 2023-07-01)
The flavour-tagging algorithms developed by the ATLAS Collaboration and used to analyse its dataset of s=13 TeV pp collisions from Run 2 of the Large Hadron Collider are presented. These new tagging algorithms are based ...
A search for heavy Higgs bosons decaying into vector bosons in same-sign two-lepton final states in pp collisions at s = 13 TeV with the ATLAS detector
(Springer Nature, 2023)
A search for heavy Higgs bosons produced in association with a vector boson and decaying into a pair of vector bosons is performed in final states with two leptons (electrons or muons) of the same electric charge, missing ...
Search for neutral long-lived particles in pp collisions at √s = 13 TeV that decay into displaced hadronic jets in the ATLAS calorimeter
(2022-06-01)
A search for decays of pair-produced neutral long-lived particles (LLPs) is presented using 139 fb−1 of proton-proton collision data collected by the ATLAS detector at the LHC in 2015–2018 at a centre-of-mass energy of 13 ...
