Description
Measurements of jets that traverse a quark gluon plasma can provide in- sights into the jet energy loss in heavy ion collisions. Furthermore, considering jets of various radii can help elucidate how the parton energy is transferred to the medium as well as the corresponding medium response. This talk presents measurements of the nuclear modification factor and dijet momentum balance for anti-kt jets reconstructed with radius R = 0.2, 0.3, 0.5, 0.4, and 0.6, obtained with the ATLAS detector at the LHC. These measurements used 1.72 nb−1 of Pb+Pb data collected in 2018, and 260 pb−1 of pp data collected in 2017, both at a per-nucleon center of mass energy √sNN = 5.02 TeV. The measurements were unfolded in jet transverse momentum to correct for the jet energy reso- lution. The measurements show a jet radius dependence of jet quenching and suppression. These measurements will improve the understanding of the jet energy loss process.
