Measurement of Jet Fragmentation in Pb+Pb and pp Collisions at √{S_{NN}} = 2.76 TeV with the ATLAS Detector at the LHC
This paper describes the implementation and performance of a particle flow algorithm applied to 20.2 fb⁻¹ of ATLAS data from 8 TeV proton–proton collisions in Run 1 of the LHC. The algorithm removes calorimeter energy ...
Measurement of the Top Quark Pair Production Charge Asymmetry in Proton-Proton Collisions at √s̅ = 7 TeV Using the ATLAS Detector
(Springer, 2014-02-25)
This paper presents a measurement of the top quark pair (tt̅) production charge asymmetry A_C using 4.7 fb−1 of proton-proton collisions at a centre-of-mass energy √s̅ = 7 TeV collected by the ATLAS detector at the LHC. A ...
Properties of g → bb̅ at Small Opening Angles in pp Collisions with the ATLAS Detector at √s =13 TeV
The fragmentation of high-energy gluons at small opening angles is largely unconstrained by present measurements. Gluon splitting to b-quark pairs is a unique probe into the properties of gluon fragmentation because ...
Studies of Zγ Production in Association with a High-Mass Dijet System in pp Collisions at √s̅ = 8 TeV with the ATLAS Detector
(American Physical Society, 2018-05-15)
Dijet events are studied in the proton-proton collision data set recorded at √s̅ = 13 TeV with the ATLAS detector at the Large Hadron Collider in 2015 and 2016, corresponding to integrated luminosities of 3.5 fb⁻¹ and 33.5 ...
Performance of the ATLAS Trigger System in 2015
(Springer New York LLC, 2018-05-15)
This article presents measurements of tt̅ differential cross-sections in a fiducial phase-space region, using an integrated luminosity of 3.2 fb⁻¹ of proton–proton data at a centre-of-mass energy of √s̅ = 13 TeV recorded ...
Search for Light Resonances Decaying to Boosted Quark Pairs and Produced in Association with a Photon or a Jet in Proton-Proton Collisions at √s=13 TeV with the ATLAS Detector
(Elsevier Science B.V., 2018-11-02)
This Letter presents a search for new light resonances decaying to pairs of quarks and produced in association with a high-p_{T} photon or jet. The dataset consists of proton-proton collisions with an integrated luminosity ...
Search for Heavy Resonances Decaying to a W or Z Boson and a Higgs Boson in the qq̅(′)bb̅ Final State in pp Collisions at √s =13 TeV with the ATLAS Detector
(Elsevier Science Bv, 2018-09-27)
A search for heavy resonances decaying to a W or Z boson and a Higgs boson in the qq̅(′)bb̅ final state is described. The search uses 36.1 fb⁻¹ of proton-proton collision data at √s = 13 TeV collected by the ATLAS detector ...
Femtoscopy with Identified Charged Pions in Proton-Lead Collisions at √{S_{NN}}=5.02 TeV with ATLAS
