Measurement of Distributions Sensitive to the Underlying Event in Inclusive Z-Boson Production in pp Collisions at √s = 7 TeV with the ATLAS Detector
(Springer New York LLC, 2014-12-10)
A measurement of charged-particle distributions sensitive to the properties of the underlying event is presented for an inclusive sample of events containing a Z-boson, decaying to an electron or muon pair. The measurement ...
Performance of the ATLAS Trigger System in 2015
(Springer New York LLC, 2018-05-15)
This article presents measurements of tt̅ differential cross-sections in a fiducial phase-space region, using an integrated luminosity of 3.2 fb⁻¹ of proton–proton data at a centre-of-mass energy of √s̅ = 13 TeV recorded ...
Search for Heavy Majorana Neutrinos with the ATLAS Detector in pp Collisions at √s̅ = 8 TeV
(Springer, 2015-07-29)
A search for heavy Majorana neutrinos in events containing a pair of high-p{T} leptons of the same charge and high-p{T} jets is presented. The search uses 20.3 fb⁻¹ of pp collision data collected with the ATLAS detector ...
Measurement of the Production of a W Boson in Association with a Charm Quark in pp Collisions at √s=7 TeV with the ATLAS Detector
(Springer, 2014-05-16)
The production of a W boson in association with a single charm quark is studied using 4.6 fb⁻¹ of pp collision data at√s = 7 TeV collected with the ATLAS detector at the Large Hadron Collider. In events in which a W boson ...
Search for the Standard Model Higgs Boson Decay to μ⁺μ⁻ with the ATLAS Detector
(Elsevier Science B. V., 2014-11-10)
A search is reported for Higgs boson decay to μ⁺μ⁻ using data with an integrated luminosity of 24.8 fb⁻¹ collected with the ATLAS detector in pp collisions at √s̅ = 7 and 8 TeV at the CERN Large Hadron Collider. The observed ...
Measurement of the Cross-Section of High Transverse Momentum Vector Bosons Reconstructed as Single Jets and Studies of Jet Substructure in pp Collisions at √s = 7 TeV with the ATLAS Detector
(IOP Publishing, 2014-11-04)
This paper presents a measurement of the cross-section for high transverse momentum W and Z bosons produced in pp collisions and decaying to allhadronic final states. The data used in the analysis were recorded by the ATLAS ...
Production and Integration of the ATLAS Insertable B-Layer
(IOP Publishing Ltd, 2018-11-05)
During the shutdown of the CERN Large Hadron Collider in 2013-2014, an additional pixel layer was installed between the existing Pixel detector of the ATLAS experiment and a new, smaller radius beam pipe. The motivation ...
Search for Magnetic Monopoles and Stable Particles with High Electric Charges in 8 TeV pp Collisions with the ATLAS Detector
(American Physical Society, 2016-03-18)
A search for highly ionizing particles produced in proton-proton collisions at 8 TeV center-of-mass energy is performed by the ATLAS Collaboration at the CERN Large Hadron Collider. The data set used corresponds to an ...
Performance of the ATLAS Track Reconstruction Algorithms in Dense Environments in LHC Run 2
(Springer New York LLC, 2018-05-15)
