Search for Higgs boson production in association with a high-energy photon via vector-boson fusion with decay into bottom quark pairs at s = 13 TeV with the ATLAS detector
(Springer, 2021-03-01)
A search is presented for the production of the Standard Model Higgs boson in association with a high-energy photon. With a focus on the vector-boson fusion process and the dominant Higgs boson decay into b-quark pairs, ...
The ATLAS Fast TracKer system
(IOP Publishing, 2021-07-01)
The ATLAS Fast TracKer (FTK) was designed to provide full tracking for the ATLAS high-level trigger by using pattern recognition based on Associative Memory (AM) chips and fitting in high-speed field programmable gate ...
Performance of the ATLAS RPC detector and Level-1 muon barrel trigger at √(s)=13 TeV
(IOP Publishing, 2021-07-01)
The ATLAS experiment at the Large Hadron Collider (LHC) employs a trigger system consisting of a first-level hardware trigger (L1) and a software-based high-level trigger. The L1 muon trigger system selects muon candidates, ...
Search for supersymmetry in events with four or more charged leptons in 139 fb(-1) of root s=13 TeV pp collisions with the ATLAS detector
(Springer, 2021-07-22)
A search for supersymmetry in events with four or more charged leptons (electrons, muons and τ-leptons) is presented. The analysis uses a data sample corresponding to 139 fb−1 of proton-proton collisions delivered by the ...
A search for the decays of stopped long-lived particles at root s=13 TeV with the ATLAS detector
(Springer, 2021-07-23)
A search for long-lived particles, which have come to rest within the ATLAS detector, is presented. The subsequent decays of these particles can produce high-momentum jets, resulting in large out-of-time energy deposits ...
Determination of the parton distribution functions of the proton from ATLAS measurements of differential W± and Z boson production in association with jets
(Springer, 2021-07-29)
This article presents a new set of proton parton distribution functions, ATLASepWZVjet20, produced in an analysis at next-to-next-to-leading order in QCD. The new data sets considered are the measurements of W+ and W− boson ...
Measurements of sensor radiation damage in the ATLAS inner detector using leakage currents
(IOP Publishing, 2021-08-01)
Non-ionizing energy loss causes bulk damage to the silicon sensors of the ATLAS pixel and strip detectors. This damage has important implications for data-taking operations, charged-particle track reconstruction, detector ...
