A continuous calibration of the ATLAS flavour-tagging classifiers via optimal transportation maps
ATLAS Collaboration
A calibration of the ATLAS flavour-tagging algorithms using a new calibration procedure based on optimal transportation maps is presented. Simultaneous, continuous corrections to t…
Configuration, Performance, and Commissioning of the ATLAS -jet Triggers for the 2022 and 2023 LHC data-taking periods
ATLAS Collaboration
In 2022 and 2023, the Large Hadron Collider produced approximately two billion hadronic interactions each second from bunches of protons that collide at a rate of 40 MHz. The ATLAS…
Test of lepton flavour universality in -boson decays into electrons and -leptons using collisions at TeV with the ATLAS detector
ATLAS Collaboration
A measurement of the ratio of the branching fractions, , is performed using a sample of bosons originating from top-quark decays to final s…
Observation of top-quark pair production in lead-lead collisions at TeV with the ATLAS detector
ATLAS Collaboration
Top-quark pair production is observed in lead-lead (Pb+Pb) collisions at TeV at the Large Hadron Collider with the ATLAS detector. The data sample was r…
Reconstruction and identification of pairs of collimated -leptons decaying hadronically using TeV collision data with the ATLAS detector
ATLAS Collaboration
This paper describes an algorithm for reconstructing and identifying a highly collimated hadronically decaying -lepton pair with low transverse momentum. When two -leptons ar…
