Measurement of distributions sensitive to the underlying event in inclusive Z boson production in pp collisions at root s=13 TeV with the ATLAS detector
This paper presents measurements of charged-particle distributions sensitive to the properties of the underlying event in events containing a Z boson decaying into a muon pair. The data were obtained using the ATLAS detector ...
Observation of Light-by-Light Scattering in Ultraperipheral Pb plus Pb Collisions with the ATLAS Detector
(American Physical Society, 2019-07-31)
This Letter describes the observation of the light-by-light scattering process, γ γ → γ γ , in Pb + Pb collisions at √ s NN = 5.02 TeV . The analysis is conducted using a data sample corresponding ...
Search for electroweak diboson production in association with a high-mass dijet system in semileptonic final states in pp collisions at root s=13 TeV with the ATLAS detector
(American Physical Society, 2019-08-22)
This paper reports on a search for electroweak diboson ( W W / W Z / Z Z ) production in association with a high-mass dijet system, using data from proton-proton collisions at a center-of-mass energy of ...
Measurement of the cross-section and charge asymmetry of W bosons produced in proton-proton collisions at root s=8 TeV with the ATLAS detector
This paper presents measurements of the W+→μ+ν and W−→μ−ν cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton–proton ...
Resolution of the ATLAS muon spectrometer monitored drift tubes in LHC Run 2
(IOP Publishing, 2019-09)
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 ...
Search for high-mass dilepton resonances using 139 fb(-1) of pp collision data collected at root s=13 TeV with the ATLAS detector
A search for high-mass dielectron and dimuon resonances in the mass range of 250 GeV to 6 TeV is presented. The data were recorded by the ATLAS experiment in proton–proton collisions at a centre-of-mass energy of TeV ...
