Tools for estimating fake/non-prompt lepton backgrounds with the ATLAS detector at the LHC
(IOP Publishing, 2023-11-01)
Search for a new pseudoscalar decaying into a pair of muons in events with a top-quark pair at s=13 TeV with the ATLAS detector
(American Physical Society (APS), 2023-11-01)
Luminosity determination in pp collisions at √s=13 TeV using the ATLAS detector at the LHC
(2023-10-01)
The luminosity determination for the ATLAS detector at the LHC during Run 2 is presented, with pp collisions at a centre-of-mass energy s=13 TeV. The absolute luminosity scale is determined using van der Meer beam separation ...
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 ...
Search for lepton-flavour violation in high-mass dilepton final states using 139 fb<sup> −1</sup> of pp collisions at √s = 13 TeV with the ATLAS detector
(2023-10-01)
A search is performed for a heavy particle decaying into different-flavour, dilepton final states, using 139 fb−1 of proton-proton collision data at s = 13 TeV collected in 2015–2018 by the ATLAS detector at the Large ...
