Probing nuclear matter with jets

Abstract
Jet physics in relativistic heavy ion collisions, which combines perturbative QCD jet production with quark and gluon energy loss and in-medium parton shower modification, has emerged as a powerful tool to probe the properties of strongly-interacting matter formed in high-energy nuclear reactions. We present selected results for the modification of jet cross sections and related observables in the ambiance of hot and/or dense nuclear medium. We focus on the inclusive jet spectrum and dijets [${\cal O}(α_s^3) $], and $Z^0/γ^*$ tagged jets [${\cal O}(G_Fα_s^2) $] in the framework of perturbative QCD.
