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 ...
Search for Dark Matter in Events With Heavy Quarks and Missing Transverse Momentum in pp Collisions With the ATLAS Detector
(Springer Nature, 2015)
This article reports on a search for dark matter pair production in association with bottom or top quarks in 20.3 fb−1 of pp collisions collected at s√=8 TeV by the ATLAS detector at the LHC. Events with large missing ...
Performance of the ATLAS Muon Trigger in pp Collisions at √s=8 TeV
(Springer Nature, 2015)
The performance of the ATLAS muon trigger system is evaluated with proton-proton collision data collected in 2012 at the Large Hadron Collider at a centre-of-mass energy of 8 TeV. It is primarily evaluated using events ...
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 ...
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 ...
