Electron and photon performance measurements with the ATLAS detector using the 2015-2017 LHC proton-proton collision data

Georges Aad, +2965 more

- 10 Dec 2019

- Journal of Instrumentation

TL;DR: In this article, an improved energy clustering algorithm is introduced, and its implications for the measurement and identification of prompt electrons and photons are discussed in detail, including corrections and calibrations that affect performance, including energy calibration, identification and isolation efficiencies.

- 25 Nov 2019

- European Physical Journal C

TL;DR: In this article, the ATLAS Collaboration during Run 2 of the Large Hadron Collider (LHC) was used to identify jets containing b-hadrons, and the performance of the algorithms was evaluated in the s...

Performance of electron and photon triggers in ATLAS during LHC Run 2

Georges Aad, +2957 more

- 22 Jan 2020

- European Physical Journal C

TL;DR: In this paper, the trigger algorithms and selection were optimized to control the rates while retaining a high efficiency for physics analyses at the ATLAS experiment to cope with a fourfold increase of peak LHC luminosity from 2015 to 2018 (Run 2), and a similar increase in the number of interactions per beam-crossing to about 60.

- 03 Aug 2021

- European Physical Journal C

TL;DR: In this article, the ATLAS particle-flow reconstruction method is used to reconstruct the topo-clusters of the proton-proton collision data with a center-of-mass energy of 13$ TeV collected by the LHC.

Muon reconstruction and identification efficiency in ATLAS using the full Run 2 pp collision data set at √ s = 13 TeV

Georges Aad, +2985 more

- 05 Jul 2021

- European Physical Journal C

TL;DR: In this paper, the authors describe the muon reconstruction and identification efficiency obtained by the ATLAS experiment for 139.5 million collision data collected between 2015 and 2018 during Run 2 of the LHC, and show that the improved and newly developed algorithms were deployed to preserve high muon identification efficiency with a low misidentification rate and good momentum resolution.
