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 sNNsNN = 5.02 TeV, measurements of the leading dijet transverse momentum (pTpT) correlations are presented. Additionally, measurements in Pb+Pb collisions of the dijet pair nuclear modification factors projected along leading and subleading jet pTpT are made. The measurements are performed using the ATLAS detector at the LHC with 260 pb−1−1 of pp data collected in 2017 and 2.2 nb−1−1 of Pb+Pb data collected in 2015 and 2018. An unfolding procedure is applied to the two-dimensional leading and subleading jet pTpT distributions to account for experimental effects in the measurement of both jets. Results are provided for dijets with leading jet pTpT greater than 100 GeV.
