Study of the path length dependence of jet quenching in relativistic heavy-ion collisions with JEWEL — •Luisa Bergmann for the ALICE collaboration — Physikalisches Institut, Universität Heidelberg

In relativistic heavy-ion collisions, a deconfined medium with high energy density is created, the quark-gluon plasma. Amongst other observables, jets – originating from primordial hard scatterings – act as useful probes for the properties of this medium. As the initial partons traverse the quark-gluon plasma, they lose energy by interacting with the constituents of the medium. The study of this so called "jet quenching" yields insight into the interaction properties of the medium.

This talk focuses on the study of correlation functions. By analyzing the angular dependence of the distribution of charged hadrons in two particle and multi-hadron correlations, one obtains information about the path-length dependent energy loss of jets in the medium. To provide a well formed basis for future data analyses, the study of correlations is first performed with models, in particular by employing JEWEL. The usage of Monte-Carlo event generators offers the possibility to gain knowledge about the interaction processes in a controlled environment, which can then be used to understand structures in real data. This information ultimately helps to constrain the models on energy loss and on interactions of colored probes and media.
