Measurement of the four-lepton invariant mass spectrum in 13 TeV proton-proton collisions with the ATLAS detector
A measurement of the four-lepton invariant mass spectrum is made with the ATLAS detector, using an integrated luminosity of 36.1 fb−1 of proton-proton collisions at s√ = 13 TeV delivered by the Large Hadron Collider. ...
Search for long-lived neutral particles in pp collisions at root s=13 TeV that decay into displaced hadronic jets in the ATLAS calorimeter
This paper describes a search for pairs of neutral, long-lived particles decaying in the ATLAS calorimeter. Long-lived particles occur in many extensions to the Standard Model and may elude searches for new promptly decaying ...
Cross-section measurements of the Higgs boson decaying into a pair of tau-leptons in proton-proton collisions at root s=13 TeV with the ATLAS detector
(American Physical Society, 2019-04-10)
A measurement of production cross sections of the Higgs boson in proton-proton collisions is presented in the H → τ τ decay channel. The analysis is performed using 36.1 fb − 1 of data recorded by the ...
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 ...
