ATLAS measurements of the azimuthal aniso-tropy in lead–lead collisions at √ s NN = 2.76 TeV are shown using a dataset of approximately 7 µb −1 collected at the LHC in 2010. The measurements are performed for charged particles with transverse momenta 0.5 < p T < 20 GeV and in the pseudorapidity range |η| < 2.5. The anisotropy is characterized by the Fourier(More)
A measurement of the calorimeter response to isolated charged hadrons in the ATLAS detector at the LHC is presented. This measurement is performed with 3.2 nb[Formula: see text] of proton-proton collision data at [Formula: see text] [Formula: see text] from 2010 and 0.1 nb[Formula: see text] of data at [Formula: see text] [Formula: see text] from 2012.

This paper reports 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 centre-of-mass energy √ s = 8 TeV. A range of techniques for optimising the signal jet mass resolution are combined with various jet sub-structure(More)
Studies of the spin and parity quantum numbers of the Higgs boson in the W W * → eνμν final state are presented , based on proton–proton collision data collected by the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 20.3 fb −1 at a centre-of-mass energy of √ s = 8 TeV. The Standard Model spin-parity J C P = 0 ++(More)
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 √ s = 8 TeV with the ATLAS experiment at the large hadron collider using data collected in 2012, corresponding to an integrated lumi-nosity of 20.3 fb −1. In this search, the W boson from the top quark(More)
This paper presents cross sections for the production of a W boson in association with jets, measured in proton–proton collisions at √ s = 7 TeV with the ATLAS experiment at the large hadron collider. With an integrated luminosity of 4.6 fb −1 , this data set allows for an exploration of a large kinematic range, including jet production up to a transverse(More)

Abstract This paper presents the performance of the ATLAS muon reconstruction during the LHC run with pp collisions at √ s = 7–8 TeV in 2011–2012, focusing mainly on data collected in 2012. Measurements of the reconstruction efficiency and(More)
