description | Jets are an important tool to study the hot, dense matter produced in Pb+Pb collisions at the LHC. They are produced at the early stages of the collisions and are expected to be modified as they propagate through the hot and dense medium. This leads to energy loss as well as modification of the jet structure. These proceedings highlight some of the latest jet measurements from ATLAS measured in 260 pb$^{-1}$ and 1.7 nb$^{-1}$ of \pp~and \PbPb~collision data, respectively, at 5.02 TeV per nucleon pair. The results shown include measurements of the dijet asymmetry as a function of the leading jet transverse momentum, the suppression pattern of the internal structure, revealed when reconstructing jets with the anti-$k_t$ algorithm using large radius parameters, and measurements of particles recoiling against the $Z$ boson. The data provide important information to understand the strength and mechanism of jet quenching. |
