Jet-hadron correlations in Pb–Pb collisions at √sNN = 5.02 TeV — •Jiyoung Kim for the ALICE collaboration — Physikalisches Institut, Universität Heidelberg
A Large Ion Collider Experiment (ALICE) is dedicated to study properties of Quark Gluon Plasma (QGP), which is created in ultra relativistic heavy ion collision. Jets are used as a probe to explore the strong-interacting matter, since they interact with the QGP and lose a part of their energy while passing through the medium. A quantitative understanding of the mechanisms of energy loss and the interaction of parton and medium is not yet established. Model calculations suggest the formation of Mach cones as a result of the interaction between high energetic partons and the QGP.
We present an analysis of azimuthal correlations of inclusive hadrons and identified protons with respect to the axis of charged jets in Pb–Pb collisions at √sNN = 5.02 TeV with the ALICE detector. Jet-hadron correlations allow to study medium response including the Mach cone effect. Moreover, Jet-proton correlations allow to disentangle signals from the medium and from jet fragmentation by using different proton abundances in both cases. We present correlation functions fully corrected for acceptance and tracking efficiency.
