Evidence for Higgs boson decays to a low-mass dilepton system and a photon in pp collisions at s = 13 TeV with the ATLAS detector
(Elsevier, 2021-05-01)
A search for the Higgs boson decaying into a photon and a pair of electrons or muons with an invariant mass
GeV is presented. The analysis is performed using 139 fb−1 of proton–proton collision data, produced by the LHC ...
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 ...

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 ...
