Measurement of the Inclusive Jet Cross Section in pp Collisions at √s=2.76 TeV and Comparison to the Inclusive Jet Cross Section at √s=7 TeV Using the ATLAS Detector
(Springer Nature, 2013)
Abstract : The inclusive jet cross-section has been measured in proton-proton collisions at √s=2.76 TeV in a dataset corresponding to an integrated luminosity of 0.20pb-1 collected with the ATLAS detector at the Large ...
Measurement of the Differential Cross-Sections of Prompt and Non-Prompt Production of J/ψ and ψ(2S) in Pp Collisions at √s=7 and 8 TeV With the ATLAS Detector
(Springer Nature, 2016)
The production rates of prompt and non-prompt J/ψ and ψ(2S) mesons are measured using 2.1 fb−1 and 11.4 fb−1 of data collected with the ATLAS experiment at the LHC, in proton-proton collisions at s√=7 and 8 TeV respectively. ...
Study of the B+c→J/ψD+s and B+c→J/ψD∗+s Decays With the ATLAS Detector
(Springer Nature, 2016)
The decays B+c→J/ψD+s and B+c→J/ψD∗+s are studied with the ATLAS detector at the LHC using a dataset corresponding to integrated luminosities of 4.9 and 20.6 fb−1 of pp collisions collected at centre-of-mass energies √s=7 ...
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 ...
Measurement of τ Polarization in W→τν Decays With the ATLAS Detector in pp Collisions at √s=7 TeV
(Springer Nature, 2012)
In this paper, a measurement of τ polarization in W→τν decays is presented. It is measured from the energies of the decay products in hadronic τ decays with a single final state charged particle. The data, corresponding ...
Observation and measurements of the production of prompt and non-prompt J/ψ mesons in association with a Z boson in pp collisions at √s=8 TeV with the ATLAS detector
(Springer Nature, 2015)
The production of a Z boson in association with a J/ψ meson in proton-proton collisions probes the production mechanisms of quarkonium and heavy flavour in association with vector bosons, and allows studies of multiple ...
Performance of the ATLAS Transition Radiation Tracker in Run 1 of the LHC: tracker properties
(IOP Publishing, 2017)
The tracking performance parameters of the ATLAS Transition Radiation Tracker (TRT) as part of the ATLAS inner detector are described in this paper for different data-taking conditions in proton-proton, proton-lead and ...
Measurement of charged-particle distributions sensitive to the underlying event in s√=13 TeV proton-proton collisions with the ATLAS detector at the LHC
(Springer Nature, 2017)
We present charged-particle distributions sensitive to the underlying event, measured by the ATLAS detector in proton-proton collisions at a centre-of-mass energy of 13 TeV, in low-luminosity Large Hadron Collider fills ...
Measurement of the correlations between the polar angles of leptons from top quark decays in the helicity basis at s√=7TeV using the ATLAS detector
(American Physical Society (APS), 2016)
A measurement of the correlations between the polar angles of leptons from the decay of pair-produced t and t¯ quarks in the helicity basis is reported, using proton-proton collision data collected by the ATLAS detector ...
Measurement of D∗±, D± and D±s meson production cross sections in pp collisions at s√=7 TeV with the ATLAS detector
(Elsevier BV, 2016)
The production of D∗±, D± and D±s charmed mesons has been measured with the ATLAS detector in pp collisions at s√=7 TeV at the LHC, using data corresponding to an integrated luminosity of 280nb−1. The charmed mesons have ...
