Jet-hadron correlations in Pb-Pb collisions at √sNN = 5.02 TeV with ALICE — •Jiyoung Kim for the ALICE collaboration — Physikalisches Institut, Universität Heidelberg
In the presence of Quark Gluon Plasma (QGP) created in ultra relativistic heavy ion collisions, jets probe the strongly-interacting medium. Jets are collimated sprays of particles produced from fragmenting hard scattered partons. When high energetic partons pass through the QGP, they interact with the medium and lose a part of their energy. This phenomenon, called jet quenching, has been observed as a suppression of high transverse momentum particles and disappearance of opposite side in di-jet production. A quantitative understanding of the mechanisms of parton energy loss and the parton-medium interaction is not yet established. Model calculations suggest the formation of Mach cones as a result of the interaction between partons and the QGP.
We present an analysis of azimuthal correlations of inclusive hadrons with respect to the axis of charged jets in Pb-Pb collisions at √sNN = 5.02TeV with the ALICE detector. Jet-hadron and jet-proton correlations allow to study the interaction between jets and the medium and allow to disentangle jet fragmentation and the medium response. The status of the analysis will be presented.
