A neural network clustering algorithm for the ATLAS silicon pixel detector

Georges Aad, +2911 more
TL;DR: A novel technique to identify and split clusters created by multiple charged particles in the ATLAS pixel detector using a set of artificial neural networks is presented, reducing the number of clusters shared between tracks in highly energetic jets by up to a factor of three.
Journal ArticleDOI

Measurement of the azimuthal angle dependence of inclusive jet yields in Pb+Pb collisions at √sNN=2.76 TeV with the ATLAS detector

Georges Aad, +2949 more
TL;DR: Measurements of the variation of inclusive jet suppression as a function of relative azimuthal angle, Δφ, with respect to the elliptic event plane provide insight into the path-length dependence of jet quenching.
Journal ArticleDOI

Search for magnetic monopoles in √s = 7 TeV pp collisions with the ATLAS detector

Georges Aad, +2864 more
TL;DR: In this article, a search for magnetic monopoles with the ATLAS detector at the CERN Large Hadron Collider using an integrated luminosity of 2.0 fb(-1) of pp collisions recorded at a center of the...
Journal ArticleDOI

Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

Georges Aad, +3001 more
TL;DR: In this paper, the authors measured the inclusive and dijet production cross-sections for jets containing b-hadrons (b-jets) in proton-proton collisions at a centre-of-mass energy of root s = 7 TeV, using the ATLAS detector at the LHC.
Journal ArticleDOI

Muon reconstruction efficiency and momentum resolution of the ATLAS experiment in proton–proton collisions at √s=7 TeV in 2010

Georges Aad, +2900 more
TL;DR: In this article, the performance of the muon reconstruction in the analysis of proton-proton collisions at root s = 7TeV at the LHC was described in terms of reconstruction and isolation efficiencies and momentum resolutions for different classes of reconstructed muons.
