Measurement of Distributions Sensitive to the Underlying Event in Inclusive Z-Boson Production in pp Collisions at √s = 7 TeV With the ATLAS Detector
(Springer Nature, 2014)
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 ...
Measurements of Jet Vetoes and Azimuthal Decorrelations in Dijet Events Produced in pp Collisions at √s=7 TeV Using the ATLAS Detector
(Springer Nature, 2014)
Additional jet activity in dijet events is measured using pp collisions at ATLAS at a centre-of-mass energy of √s=7 TeV, for jets reconstructed using the anti-kt algorithm with radius parameter R=0.6. This is done using ...
Search for Direct Top Squark Pair Production in Events With a Z Boson, b-Jets and Missing Transverse Momentum in √s=8 TeV pp Collisions With the ATLAS Detector
(Springer Nature, 2014)
A search is presented for direct top squark pair production using events with at least two leptons including a same-flavour opposite-sign pair with invariant mass consistent with the Z boson mass, jets tagged as originating ...
Light-Quark and Gluon Jet Discrimination in pp Collisions at √S = 7 TeV With the ATLAS Detector
(Springer Nature, 2014)
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 Measurement of the Ratio of the Production Cross Sections for W and Z Bosons in Association With Jets With the ATLAS Detector
(Springer Nature, 2014)
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√ = 7 TeV with the ATLAS experiment at the Large Hadron Collider. The measurement is ...
Measurement of the Centrality and Pseudorapidity Dependence of the Integrated Elliptic Flow in Lead–lead Collisions at √sNN=2.76TeV With the ATLAS Detector
(Springer Nature, 2014)
The integrated elliptic flow of charged particles produced in Pb+Pb collisions at sNN=2.76 TeV has been measured with the ATLAS detector using data collected at the Large Hadron Collider. The anisotropy parameter, v2, was ...
Search for Contact Interactions and Large Extra Dimensions in the Dilepton Channel Using Proton–proton Collisions at √s = 8 TeV With the ATLAS Detector
(2014)
Research 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 ...
Measurement of Flow Harmonics With Multi-Particle Cumulants in Pb+Pb Collisions at √sNN =2.76 TeV With the ATLAS Detector
(Springer Nature, 2014)
[en] ATLAS measurements of the azimuthal anisotropy in lead.lead collisions at √sNN = 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 ...
Muon Reconstruction Efficiency and Momentum Resolution of the ATLAS Experiment in Proton–proton Collisions at √s=7 TeV in 2010
(Springer Nature, 2014)
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 ...
