Jet radius dependence of dijet momentum balance and suppression in Pb + Pb collisions at 5.02 TeV with the ATLAS detector

Popis výsledku v původním jazyce

This paper describes a measurement of the jet radius dependence of the dijet momentum balance between leading back-to-back jets in 1.72nb−1 of Pb+Pb collisions collected in 2018 and 255pb−1 of pp collisions collected in 2017 by the ATLAS detector at the LHC. Both datasets were collected at √sNN=5.02 TeV. Jets are reconstructed using the anti-kt algorithm with jet radius parameters R=0.2, 0.3, 0.4, 0.5, and 0.6. The dijet momentum balance distributions are constructed for leading jets with transverse momentum pT from 100 to 562 GeV for R=0.2, 0.3, and 0.4 jets, and from 158 to 562 GeV for R=0.5 and 0.6 jets. The absolutely normalized dijet momentum balance distributions are constructed to compare measurements of the dijet yields in Pb+Pb collisions directly to the dijet cross sections in pp collisions. For all jet radii considered here, there is a suppression of more balanced dijets in Pb+Pb collisions compared with pp collisions, while for more imbalanced dijets there is an enhancement.n
