The PreProcessor of the ATLAS Level-1 Calorimeter Trigger prepares the analogue trigger signals sent from the ATLAS calorimeters by digitising, synchronising, and calibrating them to reconstruct transverse energy deposits, ...

Inclusive and differential fiducial cross sections of the Higgs boson are measured in the H→ZZ∗→4ℓ (ℓ=e,μ) decay channel. The results are based on proton-proton collision data produced at the Large Hadron Collider at a ...

The elliptic flow of muons from the decay of charm and bottom hadrons is measured in pp collisions at √s=13  TeV using a data sample with an integrated luminosity of 150  pb−1 recorded by the ATLAS detector at the LHC. The ...

The inclusive top quark pair (tt¯) production cross-section σtt¯ has been measured in proton–proton collisions at s√=13TeV, using 36.1 fb−1 of data collected in 2015–2016 by the ATLAS experiment at the LHC. Using events ...

The prevalence of hadronic jets at the LHC requires that a deep understanding of jet formation and structure is achieved in order to reach the highest levels of experimental and theoretical precision. There have been many ...

A search for the electroweak production of charginos and sleptons decaying into final states with two electrons or muons is presented. The analysis is based on 139 fb−1 of proton–proton collisions recorded by the ATLAS ...
