This paper presents the electron and photon energy calibration achieved with the ATLAS detector using about 25 fb −1 of LHC proton–proton collision data taken at centre-of-mass energies of s√=7 and 8 TeV. The reconstruction ...

A search for squarks and gluinos in final states containing high-p T jets, missing transverse momentum and no electrons or muons is presented. The data were recorded in 2012 by the ATLAS experiment in s√=8 TeV proton-proton ...

A search is presented for the production of new heavy quarks that decay to a Z boson and a third-generation Standard Model quark. In the case of a new charge +2/3 quark (T ), the decay targeted is T → Zt, while the decay ...

ATLAS measurements of the azimuthal anisotropy in lead–lead collisions at √sNN = 2.76 TeV are shown using a dataset of approximately 7μb−1 collected at the LHC in 2010. The measurements are performed for charged particles ...

A likelihood-based discriminant for the identification of quark- and gluon-initiated jets is built and validated using 4.7 fb −1 of proton–proton collision data at s√=7 TeV collected with the ATLAS detector at the LHC. ...

A search is conducted for non-resonant new phenomena in dielectron and dimuon final states, originating from either contact interactions or large extra spatial dimensions. The LHC 2012 proton–proton collision dataset ...

A measurement of charged-particle distributions sensitive to the properties of the underlying event is presented for an inclusive sample of events containing a Z-boson, decaying to an electron or muon pair. The measurement ...

The ratio of the production cross sections for W and Z bosons in association with jets has been measured in proton–proton collisions at s√=7TeV with the ATLAS experiment at the Large Hadron Collider. The measurement is ...

This paper presents a study of the performance of the muon reconstruction in the analysis of proton–proton collisions at s√=7 TeV at the LHC, recorded by the ATLAS detector in 2010. This performance is described in terms ...
