Measurement of b-hadron pair production with the ATLAS detector in proton-proto...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

A measurement of b-hadron pair production is presented, based on a data set corresponding to an integrated luminosity of 11.4 fb−1 of proton-proton collisions recorded at s√=8 TeV with the ATLAS detector at the LHC. Events are selected in which a b-hadron is reconstructed in a decay channel containing J/ψ → μμ, and a second b-hadron is reconstructed in a decay channel containing a muon. Results are presented in...


Determination of the strong coupling constant alpha(s) from transverse energy-e...

Onofre, A.; Castro, Nuno Filipe; ATLAS Collaboration

Measurements of transverse energy-energy correlations and their associated asymmetries in multi-jet events using the ATLAS detector at the LHC are presented. The data used correspond to vs = 8 TeV proton-proton collisions with an integrated luminosity of 20.2 fb(-1). The results are presented in bins of the scalar sum of the transverse momenta of the two leading jets, unfolded to the particle level and compared...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

In the original paper, Fig. 4 contains the wrong label preliminary. The label has been fixed, while none of the results have changed.; The online version of the original article can be found under doi:10.1140/epjc/s10052-016-3910-6


Measurement of the t(t)over-bar gamma production cross section in proton-proton...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

The cross section of a top-quark pair produced in association with a photon is measured in proton-proton collisions at a centre-of-mass energy of s√=8 TeV with 20.2 fb−1 of data collected by the ATLAS detector at the Large Hadron Collider in 2012. The measurement is performed by selecting events that contain a photon with transverse momentum pT > 15 GeV, an isolated lepton with large transverse momentum, large ...


Study of WWγ and WZγ production in pp collisions at s√=8TeV and search for anom...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

This paper presents a study of WWγ and WZγ triboson production using events from proton–proton collisions at a centre-of-mass energy of s√=8TeV recorded with the ATLAS detector at the LHC and corresponding to an integrated luminosity of 20.2 fb−1. The WWγ production cross-section is determined using a final state containing an electron, a muon, a photon, and neutrinos (eνμνγ). Upper limits on the production cro...


Measurements of electroweak Wjj production and constraints on anomalous gauge c...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

Measurements of the electroweak production of a W boson in association with two jets at high dijet invariant mass are performed using s√= 7 and 8 TeV proton–proton collision data produced by the Large Hadron Collider, corresponding respectively to 4.7 and 20.2 fb−1 of integrated luminosity collected by the ATLAS detector. The measurements are sensitive to the production of a W boson via a triple-gauge-boson ver...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

Measurements of the production cross section of a Z boson in association with jets in proton–proton collisions at s√=13 TeV are presented, using data corresponding to an integrated luminosity of 3.16 fb−1 collected by the ATLAS experiment at the CERN Large Hadron Collider in 2015. Inclusive and differential cross sections are measured for events containing a Z boson decaying to electrons or muons and produced i...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

The distributions of transverse momentum and longitudinal momentum fraction of charged particles in jets are measured in Pb+Pb and pp collisions with the ATLAS detector at the LHC. The distributions are measured as a function of jet transverse momentum and rapidity. The analysis utilises an integrated luminosity of 0.14 nb−1 of Pb+Pb data and 4.0 pb−1 of pp data collected in 2011 and 2013, respectively, at the ...


Fiducial, total and differential cross-section measurements of t-channel single...

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

Detailed measurements of t-channel single top-quark production are presented. They use 20.2 fb−1 of data collected by the ATLAS experiment in proton–proton collisions at a centre-of-mass energy of 8 TeV at the LHC. Total, fiducial and differential cross-sections are measured for both top-quark and top-antiquark production. The fiducial cross-section is measured with a precision of 5.8% (top quark) and 7.8% (top...


Performance of the ATLAS trigger system in 2015

Onofre, A.; Castro, Nuno Filipe Silva Fernandes; ATLAS Collaboration

During 2015 the ATLAS experiment recorded 3.8fb−1 of proton–proton collision data at a centre-of-mass energy of 13TeV. The ATLAS trigger system is a crucial component of the experiment, responsible for selecting events of interest at a recording rate of approximately 1 kHz from up to 40 MHz of collisions. This paper presents a short overview of the changes to the trigger and data acquisition systems during the ...
