• #### Determination of jet calibration and energy resolution in proton–proton collisions at √s=8TeV using the ATLAS detector ﻿

(Journal article; Peer reviewed, 2020)
The jet energy scale, jet energy resolution, and their systematic uncertainties are measured for jets reconstructed with the ATLAS detector in 2012 using proton–proton data produced at a centre-of-mass energy of 8 TeV with ...
• #### Fluctuations of anisotropic flow in Pb+Pb collisions at √sNN = 5.02 TeV with the ATLAS detector ﻿

(Journal article; Peer reviewed, 2020-01-09)
Multi-particle azimuthal cumulants are measured as a function of centrality and transverse momentum using 470 μb−1 of Pb+Pb collisions at sNN−−−√ = 5.02 TeV with the ATLAS detector at the LHC. These cumulants provide ...
• #### Measurement of J/ψ production in association with a W± boson with pp data at 8 TeV ﻿

(Journal article; Peer reviewed, 2020-01-16)
A measurement of the production of a prompt J/ψ meson in association with a W± boson with W± → μν and J/ψ → μ+μ− is presented for J/ψ transverse momenta in the range 8.5–150 GeV and rapidity |yJ/ψ| < 2.1 using ATLAS data ...
• #### Measurement of long-range two-particle azimuthal correlations in Z-boson tagged pp collisions at √s=8 and 13 TeV ﻿

(Journal article; Peer reviewed, 2020-01-25)
Results are presented from the measurement by ATLAS of long-range (|Δη|>2) dihadron angular correlations in s√=8 and 13 TeV pp collisions containing a Z boson. The analysis is performed using 19.4 fb−1 of s√=8 TeV data ...

(Journal article; Peer reviewed, 2021)
The total cross section and differential cross sections for the production of B±c mesons, times their branching fraction to J/ψπ±, are measured relative to those for the production of B± mesons, times their branching ...
