Monitoring and data quality assessment of the ATLAS liquid argon calorimeter

Georges Aad, +2898 more
- 01 Jul 2014 - 
TL;DR: In this paper, an advanced data monitoring procedure was designed to quickly identify issues that would affect detector performance and ensure that only the best quality data are used for physics analysis, and the validation procedure developed during the 2011 and 2012 LHC data-taking periods, in which more than 98% of the proton-proton luminosity recorded by ATLAS at a centre-of-mass energy of 7-8 TeV had calorimeter data quality suitable for physics analyses.
Journal ArticleDOI

Measurement of the b-hadron production cross section using decays to D⁎+μ−X final states in pp collisions at s=7 TeV with the ATLAS detector

Georges Aad, +2897 more
- 21 Nov 2012 - 
TL;DR: The b-hadron production cross section is measured with the ATLAS detector in pp collisions at root s = 7 TeV, using 3.3 pb(-1) of integrated luminosity, collected during the 2010 LHC run.
Journal ArticleDOI

Measurement of the W→τντ cross section in pp collisions at √s = 7 TeV with the ATLAS experiment

Georges Aad, +3014 more
- 05 Jan 2012 - 
TL;DR: In this article, the cross section for the production of W bosons with subsequent decay W to tau nu is measured with the ATLAS detector at the LHC using a data sample that was recorded in 2010 at a proton-proton center-of-mass energy of sqrt(s) = 7 TeV and corresponds to an integrated luminosity of 34 pb^-1.
Journal ArticleDOI

Measurement of the production of neighbouring jets in lead–lead collisions at √sNN=2.76 TeV with the ATLAS detector

Georges Aad, +2910 more
- 17 Dec 2015 - 
TL;DR: In this paper, the authors measured the production of nearby jets in Pb+Pb collisions at root s(NN) = 2.76 TeV using the ATLAS detector at the Large Hadron Collider.
Journal ArticleDOI

Search for a heavy Standard Model Higgs boson in the channel H→ZZ→ℓ+ℓ-qq¯ using the ATLAS detector

Georges Aad, +3016 more
- 16 Jan 2012 - 
TL;DR: In this paper, a search for a heavy Standard Model Higgs boson decaying via H -> ZZ -> l(+)l(-)q (q) over bar, where l = e, mu, is presented.
