The momentum measurement capability of the ATLAS muon spectrometer relies fundamentally on the intrinsic single-hit spatial resolution of the monitored drift tube precision tracking chambers. Optimal resolution is achieved ...

This paper describes a study of techniques for identifying Higgs bosons at high transverse momenta decaying into bottom-quark pairs, H → bb¯, for proton–proton collision data collected by the ATLAS detector at the Large ...

Studies of the fragmentation of jets into charged particles in heavy-ion collisions can provide information about the mechanism of jet quenching by the hot and dense QCD matter created in such collisions, the quark-gluon ...

Single- and double-differential cross-section measurements are presented for the production of top-quark pairs, in the lepton + jets channel at particle and parton level. Two topologies, resolved and boosted, are considered ...

The production of a prompt photon in association with a Z boson is studied in proton-proton collisions at a centre-of-mass energy s√ = 13 TeV. The analysis uses a data sample with an integrated luminosity of 139 fb−1 ...

This paper presents results of searches for the electroweak production of supersymmetric particles in models with compressed mass spectra. The searches use 139  fb−1 of √s=13  TeV proton-proton collision data collected by ...
