Observation of an Excess of Dicharmonium Events in the Four-Muon Final State with the ATLAS Detector.
(2023-10-13)
A search is made for potential ccc[over ¯]c[over ¯] tetraquarks decaying into a pair of charmonium states in the four muon final state using proton-proton collision data at sqrt[s]=13 TeV, corresponding to an integrated ...
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 ...
Measurement of Suppression of Large-Radius Jets and Its Dependence on Substructure in Pb+Pb Collisions at sqrt[s_{NN}]=5.02 TeV with the ATLAS Detector.
(2023-10-27)
This letter presents a measurement of the nuclear modification factor of large-radius jets in sqrt[s_{NN}]=5.02 TeV Pb+Pb collisions by the ATLAS experiment. The measurement is performed using 1.72 nb^{-1} and 257 pb^{-1} ...
Search for periodic signals in the dielectron and diphoton invariant mass spectra using 139 fb<sup>−1</sup> of pp collisions at √s = 13 TeV with the ATLAS detector
(2023-10-01)
A search for physics beyond the Standard Model inducing periodic signals in the dielectron and diphoton invariant mass spectra is presented using 139 fb−1 of s = 13 TeV pp collision data collected by the ATLAS experiment ...
