Search for long-lived neutral particles decaying into lepton jets in proton--proton collisions at s√ = 8 TeV with the ATLAS detector
(Springer, 2014-11)
Several models of physics beyond the Standard Model predict neutral particles that decay into final states consisting of collimated jets of light leptons and hadrons (so-called "lepton jets"). These particles can also be ...
Measurement of the centrality and pseudorapidity dependence of the integrated elliptic flow in lead-lead collisions at √ sNN = 2.76 TeV with the ATLAS detector
(Springer, 2014-05)
The integrated elliptic flow of charged particles produced in Pb+Pb collisions at sNN−−−√=2.76 TeV has been measured with the ATLAS detector using data collected at the Large Hadron Collider. The anisotropy parameter, v2 ...
Measurement of the W±Z boson pair-production cross section in pp collisions at s√=13 TeV with the ATLAS Detector
(Elsevier Science, 2016-09)
The production of events in proton–proton collisions at a centre-of-mass energy of is measured with the ATLAS detector at the LHC. The collected data correspond to an integrated luminosity of . The candidates are ...
Measurements of jet vetoes and azimuthal decorrelations in dijet events produced in pp collisions at s√ = 7 TeV using the ATLAS detector
(Springer, 2014-07)
Additional jet activity in dijet events is measured using pp collisions at ATLAS at a centre-of-mass energy of 7TeV , for jets reconstructed using the anti-kt algorithm with radius parameter R=0.6 . This is done using ...
Search for squarks and gluinos with the ATLAS detector in final states with jets and missing transverse momentum using 4.7 fb-1 of √s = 7 TeV proton-proton collision data
(American Physical Society, 2013-01)
A search for squarks and gluinos in final states containing jets, missing transverse momentum and no high-pT electrons or muons is presented. The data represent the complete sample recorded in 2011 by the ATLAS experiment ...
Search for nonpointing and delayed photons in the diphoton and missing transverse momentum final state in 8 TeV pp collisions at the LHC using the ATLAS detector
(American Physical Society, 2014-09)
A search has been performed, using the full 20.3 fb-1 data sample of 8 TeV proton-proton collisions collected in 2012 with the ATLAS detector at the LHC, for photons originating from a displaced vertex due to the decay ...

(Springer, 2016-11)
This paper presents the extended results of measurements of W±W± j j production and limits on anomalous quartic gauge couplings using 20.3 fb−1 of proton–proton collision data at √ s = 8 TeV recorded by the ATLAS detector ...
Search for four-top-quark production in the single-lepton and opposite-sign dilepton final states in pp collisions at s√ = 13 TeV with the ATLAS detector
(American Physical Society, 2018-11)
A search for four-top-quark production, tt¯tt¯, is presented. It is based on proton-proton collision data with a center-of-mass energy s=13 TeV collected by the ATLAS detector at the Large Hadron Collider during the years ...
Evidence for light-by-light scattering in heavy-ion collisions with the ATLAS detector at the LHC
(Nature Publishing Group, 2017-02)
Light-by-light scattering (γγ → γγ) is a quantum-mechanical process that is forbidden in the classical theory of electrodynamics. This reaction is accessible at the Large Hadron Collider thanks to the large electromagnetic ...
Measurements of differential cross sections of top quark pair production in association with jets in pp collisions at s√=13 TeV using the ATLAS detector
(Springer, 2018-02)
Measurements of differential cross sections of top quark pair production in association with jets by the ATLAS experiment at the LHC are presented. The measurements are performed as functions of the top quark transverse ...
