Search for top squark pair production in final states with one isolated lepton, jets, and missing transverse momentum in √s=8 TeV pp collisions with the ATLAS detector

Georges Aad, +2926 more
- 02 Jul 2014 - 
TL;DR: In this article, the results of a search for top squark (stop) pair production in final states with one isolated lepton, jets, and missing transverse momentum are reported.
Journal ArticleDOI

Search for the standard model Higgs boson in the diphoton decay channel with 4.9fb -1 of pp collision data at √s=7TeV with atlas

Georges Aad, +3100 more
- 13 Mar 2012 - 
TL;DR: In this article, a search for the standard model Higgs boson is performed in the diphoton decay channel, and the largest excess with respect to the background-only hypothesis is observed at 126.5 GeV, with a local significance of 2.8 standard deviations.
Journal ArticleDOI

Jet energy resolution in proton-proton collisions at s√=7 TeV recorded in 2010 with the ATLAS detector

Georges Aad, +2866 more
- 02 Mar 2013 - 
TL;DR: In this article, the authors measured the jet energy resolution using data recorded with the ATLAS detector in proton-proton collisions at root s = 7 TeV, which corresponds to an integrated luminosity of 35 pb(-1).

Readiness of the ATLAS Tile Calorimeter for LHC collisions.

Georges Aad, +2568 more
- 01 Dec 2010 - 
TL;DR: An overview of the Tile Calorimeter performance as measured using random triggers, calibration data, data from cosmic ray muons and single beam data and the determination of the global energy scale was performed with an uncertainty of 4%.
