Journal ArticleDOI

A search for prompt lepton-jets in pp collisions at √s = 8 TeV with the ATLAS detector

Georges Aad, +2899 more
- 09 Feb 2016 - 
TL;DR: In this paper, a search is presented for a new light boson with a mass of about 1 GeV and decaying promptly to jets of collimated electrons and/or muons (lepton-jets).
Journal ArticleDOI

Studies of the performance of the ATLAS detector using cosmic-ray muons

Georges Aad, +2531 more
- 29 Mar 2011 - 
TL;DR: In this paper, the results of performance studies related to combined tracking, lepton identification and the reconstruction of jets and missing transverse energy are compared to expectations based on a cosmic-ray event generator and a full simulation of the detector response.
Journal ArticleDOI

Search for new phenomena in photon + jet events collected in proton-proton collisions at √s = 8 TeV with the ATLAS detector

Georges Aad, +2947 more
- 01 Jan 2014 - 
TL;DR: In this article, a model-independent search for the production of new resonances in photon + jet (gamma + jet) events using 20 fb(-1) of proton-proton LHC data recorded with the ATLAS detector is described.
Journal ArticleDOI

Search for pair production of heavy top-like quarks decaying to a high-p(T) W boson and a b quark in the lepton plus jets final state at root s=7 TeV with the ATLAS detector

Georges Aad, +2892 more
- 29 Jan 2013 - 
TL;DR: In this article, the authors presented a search for production of a heavy up-type quark (t') together with its antiparticle, assuming a significant branching ratio for subsequent decay into a W boson and a b quark.
Journal ArticleDOI

Search for invisible particles produced in association with single-top-quarks in proton–proton collisions at √s = 8 Tev with the ATLAS detector

Georges Aad, +2862 more
- 18 Feb 2015 - 
TL;DR: In this article, a search for the production of single-top-quarks in association with missing energy is performed in proton-proton collisions at a centre-of-mass energy of [Formula: see text] with the ATLAS experiment at the large hadron collider using data collected in 2012.
