Measurements of inclusive and differential fiducial cross-sections of t(t)over-bar gamma production in leptonic final states at root s=13 TeV in ATLAS
Inclusive and differential cross-sections for the production of a top-quark pair in association with a photon are measured with proton-proton collision data corresponding to an integrated luminosity of 36.1 fb −1 , ...
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 ...
Erratum to: Search for supersymmetry in final states with two same-sign or three leptons and jets using 36 fb−1 of s√ = 13 TeV pp collision data with the ATLAS detector
Erratum to: JHEP09(2017)084
Modelling radiation damage to pixel sensors in the ATLAS detector
(IOP Publishing, 2019-06)
Silicon pixel detectors are at the core of the current and planned upgrade of the ATLAS experiment at the LHC. Given their close proximity to the interaction point, these detectors will be exposed to an unprecedented amount ...
Combination of Searches for Invisible Higgs Boson Decays with the ATLAS Experiment
(American Physical Society, 2019-06-13)
Dark matter particles, if sufficiently light, may be produced in decays of the Higgs boson. This Letter presents a statistical combination of searches for H → invisible decays where H is produced according to the ...
Searches for third-generation scalar leptoquarks in root s=13 TeV pp collisions with the ATLAS detector
Limits are set on the pair production of scalar leptoquarks, where all possible decays of the leptoquark into a quark (t, b) and a lepton (τ, ν) of the third generation are considered. The limits are presented as a function ...
Search for scalar resonances decaying into mu(+)mu(-) in events with and without b-tagged jets produced in proton-proton collisions at root s=13 TeV with the ATLAS detector
A search for a narrow scalar resonance decaying into an opposite-sign muon pair produced in events with and without b-tagged jets is presented in this paper. The search uses 36.1 fb−1 of s√=13 TeV proton-proton collision ...
