Observation of a new particle in the search for the Standard Model Higgs boson with the ATLAS detector at the LHC

Georges Aad, +2967 more
- 17 Sep 2012 - 
TL;DR: In this article, a search for the Standard Model Higgs boson in proton-proton collisions with the ATLAS detector at the LHC is presented, which has a significance of 5.9 standard deviations, corresponding to a background fluctuation probability of 1.7×10−9.

The ATLAS Experiment at the CERN Large Hadron Collider

Georges Aad, +3032 more
TL;DR: The ATLAS detector as installed in its experimental cavern at point 1 at CERN is described in this paper, where a brief overview of the expected performance of the detector when the Large Hadron Collider begins operation is also presented.
Journal ArticleDOI

The ATLAS Simulation Infrastructure

Georges Aad, +2585 more
- 25 Sep 2010 - 
TL;DR: The simulation software for the ATLAS Experiment at the Large Hadron Collider is being used for large-scale production of events on the LHC Computing Grid, including supporting the detector description, interfacing the event generation, and combining the GEANT4 simulation of the response of the individual detectors.
Journal ArticleDOI

Observation of a centrality-dependent dijet asymmetry in lead-lead collisions at √sNN=2.76 Tev with the ATLAS detector at the LHC

Georges Aad, +3101 more
- 13 Dec 2010 - 
TL;DR: In this article, the authors used the ATLAS detector to detect dijet asymmetry in the collisions of lead ions at the Large Hadron Collider and found that the transverse energies of dijets in opposite hemispheres become systematically more unbalanced with increasing event centrality, leading to a large number of events which contain highly asymmetric di jets.
Journal ArticleDOI

Evidence for the spin-0 nature of the Higgs boson using ATLAS data

Georges Aad, +2945 more
- 04 Jul 2013 - 
TL;DR: In this paper, the spin and parity quantum numbers of the Higgs boson were studied based on the collision data collected by the ATLAS experiment at the LHC, and the results showed that the standard model spin-parity J(...
