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 ...
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 ...
Search for New Phenomena in Final States with Large Jet Multiplicities and Missing Transverse Momentum with ATLAS Using √s̅ = 13 TeV proton-proton Collisions
(Elsevier, 2016-04-06)
Results are reported of a search for new phenomena, such as supersymmetric particle production, that could be observed in high-energy proton-proton collisions. Events with large numbers of jets, together with missing ...
Search for Single Production of a Vector-Like Quark via a Heavy Gluon in the 4b Final State with the ATLAS Detector in pp Collisions at √s̅ = 8 TeV
(Elsevier, 2016-05-03)
A search is performed for the process pp → G* → B_{H}b̅ / B̅_{H}b → Hbb̅ → bb̅bb̅ predicted in composite Higgs scenarios, where G* is a heavy colour octet vector resonance and B_{H} a vector-like quark of charge -1/3. The ...
Search for Triboson W^±W^±W^∓ Production in pp Collisions at √s̅ = 8 TeV with the ATLAS Detector
This paper presents the method and performance of primary vertex reconstruction in proton–proton collision data recorded by the ATLAS experiment during Run 1 of the LHC. The studies presented focus on data taken during ...
Measurement of the Prompt J/ψ Pair Production Cross-Section in pp Collisions at √s̅ = 8 TeV with the ATLAS Detector
(Springer New York LLC, 2018-05-15)
A measurement of the calorimeter response to isolated charged hadrons in the ATLAS detector at the LHC is presented. This measurement is performed with 3.2 nb⁻¹ of proton–proton collision data at √s̅ = 7 TeV from 2010 and ...
Search for Dark Matter in Association with a Higgs Boson Decaying to B-Quarks in pp Collisions at √s = 13 TeV with the ATLAS Detector
A search for dark matter pair production in association with a Higgs boson decaying to a pair of bottom quarks is presented, using 3.2 fb(-1) of pp collisions at a centre-of-mass energy of 13 TeV collected by the ATLAS ...
Measurement of the tt̅ Z and tt̅ W Production Cross Sections in Multilepton Final States using 3.2 fb⁻¹ of pp Collisions at √s = 13 TeV with the ATLAS Detector
(Springer New York LLC, 2018-05-15)
The production of two prompt J/ψ mesons, each with transverse momenta p_T > 8.5 GeV and rapidity |y| < 2.1 , is studied using a sample of proton-proton collisions at √s̅ = 8 TeV, corresponding to an integrated luminosity ...
