Measurement of vector boson production cross sections and their ratios using pp collisions at s=13.6 TeV with the ATLAS detector
(2024-07-01)
Fiducial and total W± and Z boson cross sections, their ratios and the ratio of top-antitop-quark pair and W-boson fiducial cross sections are measured in proton–proton collisions at a centre-of-mass energy of s=13.6 TeV, ...
Measurement of t-channel single-top-quark production in pp collisions at s=5.02 TeV with the ATLAS detector
(2024-07-01)
The observation of the electroweak production of single-top-quarks is made using 255 pb−1 of proton-proton collision data recorded at s=5.02 TeV with the ATLAS detector at the Large Hadron Collider. An event selection is ...
Electron and photon efficiencies in LHC Run 2 with the ATLAS experiment
(Springer Nature, 2024-05-14)
Precision measurements of electron reconstruction, identification, and isolation efficiencies and photon identification efficiencies are presented. They use the full Run 2 data sample collected by the ATLAS experiment in ...
Test of CP-invariance of the Higgs boson in vector-boson fusion production and in its decay into four leptons
(Springer Nature, 2024-05-09)
A search for CP violation in the decay kinematics and vector-boson fusion production of the Higgs boson is performed in the H → ZZ* → 4ℓ (ℓ = e, μ) decay channel. The results are based on proton-proton collision data ...
Search for pair-production of vector-like quarks in lepton+jets final states containing at least one b-tagged jet using the Run 2 data from the ATLAS experiment
(2024-07-01)
A search is presented for the pair-production of heavy vector-like quarks in the lepton+jets final state using 140 fb−1 of proton–proton collisions at s=13 TeV collected with the ATLAS detector. The search is optimised for ...
Search for Nearly Mass-Degenerate Higgsinos Using Low-Momentum Mildly Displaced Tracks in pp Collisions at s=13 TeV with the ATLAS Detector
(American Physical Society (APS), 2024-05-31)
Untitled
(27-06-2024)
A combination of fifteen top quark mass measurements performed by the ATLAS and CMS experiments at the LHC is presented. The datasets used correspond to an integrated luminosity of up to 5 and 20 fb^{-1} of proton-proton ...
Measurement of the VH,H → ττ process with the ATLAS detector at 13 TeV
(Elsevier, 2024-06-25)
A measurement of the Standard Model Higgs boson produced in association with a W or Z boson and decaying into a pair of τ-leptons is presented. This search is based on proton-proton collision data collected at s=13 TeV by ...
