Expected performance of the ATLAS experiment - detector, trigger and physics

Georges Aad, +2598 more
TL;DR: In this paper, a detailed study of the expected performance of the ATLAS detector is presented, together with the reconstruction of tracks, leptons, photons, missing energy and jets, along with the performance of b-tagging and the trigger.
Journal ArticleDOI

Identification of boosted, hadronically decaying W bosons and comparisons with ATLAS data taken at √s = 8 TeV

Georges Aad, +2850 more
TL;DR: In this paper, a detailed study of techniques for identifying boosted, hadronically decaying W bosons using 20.3 fb −¹ of proton-proton collision data collected by the ATLAS detector at the LHC at a center-of-mass energy √s = 8 TeV.
Journal ArticleDOI

Search for a light Higgs boson decaying to long-lived weakly interacting particles in proton-proton collisions at √s=7TeV with the atlas detector

Georges Aad, +3052 more
TL;DR: No excess of events is observed above the expected background and limits on the Higgs boson production times branching ratio to weakly interacting, long-lived particles are derived as a function of the particle proper decay length.
Journal ArticleDOI

Measurement of top quark polarization in top-antitop events from proton-proton collisions at √s=7 TeV using the ATLAS detector.

Georges Aad, +2948 more
TL;DR: Measurements of the polarization of the top quark in top-antitop quark pair events, using 4.7 fb(-1) of proton-proton collision data recorded with the ATLAS detector at the Large Hadron Collider at √s=7‬TeV, are in good agreement with the standard model prediction of negligible top quarks polarization.
Journal ArticleDOI

Search for WZ resonances in the fully leptonic channel using pp collisions at s=8 TeV with the ATLAS detector

Georges Aad, +2908 more
- 07 Oct 2014 - 
TL;DR: In this paper, a search for resonant WZ production in the l nu l'l' (l, l = e, mu) decay channel using 20.3 fb(-1) of root s = 8 TeV pp collision data collected by the ATLAS experiment at LHC is presented.
