Erratum: Measurements of the suppression and correlations of dijets in Pb+Pb collisions at sNN =5.02 TeV (Phys. Rev. C (2023) 107 (054908) DOI: 10.1103/PhysRevC.107.054908)

Figure 3 replaces the one in the original paper. In the original paper, the figure was incorrectly evaluated for dijets without the inclusion of a Δ⁢𝜙>7⁢𝜋/8 cut. The content of the figure is updated to reflect the dijet definition in the article through the inclusion of the Δ⁢𝜙 cut listed on the figure. The correct values of the jet fractions quoted in the paper are 47% (69%) at 100 GeV and 82% (83%) at 200 GeV in central Pb +Pb collisions (pp collisions). This is isolated to this single figure and the results and conclusions of the original article are not affected.

Studies of the correlations of the two highest transverse momentum (leading) jets in individual Pb+Pb collision events can provide information about the mechanism of jet quenching by the hot and dense matter created in such collisions. In Pb+Pb and pp collisions at√sNN = 5.02 TeV, measurements of the leading dijet transverse momentum (pT) correlations are presented. Additionally, measurements in Pb+Pb collisions of the dijet pair nuclear modification factors projected along leading and subleading jet pT are made. The measurements are performed using the ATLAS detector at the LHC with 260 pb−1 of pp data collected in 2017 and 2.2 nb−1 of Pb+Pb data collected in 2015 and 2018. An unfolding procedure is applied to the two-dimensional leading and subleading jet pT distributions to account for experimental effects in the measurement of both jets. Results are provided for dijets with leading jet pT greater than 100 GeV. Measurements of the dijet-yield-normalized xJ distributions in Pb+Pb collisions show an increased fraction of imbalanced jets compared to pp collisions; these measurements are in agreement with previous measurements of the same quantity at 2.76 TeV in the overlapping kinematic range. Measurements of the absolutely normalized dijet rate in Pb+Pb and pp collisions are also presented, and show that balanced dijets are significantly more suppressed than imbalanced dijets in Pb+Pb collisions. It is observed in the measurements of the pair nuclear modification factors that the subleading jets are significantly suppressed relative to leading jets with pT between 100 and 316 GeV for all centralities in Pb+Pb collisions.
