Jet Quenching in the light of Perturbative QCD

Korinna Zapp (Durham University)


Over the last decade, experiments at RHIC and at the LHC have demonstrated that the fragmentation pattern of highly energetic partons is altered strongly in ultra-relativistic nucleus-nucleus collisions. This so-called jet quenching motivates using such hard processes as well-calibrated hard probes of dense QCD matter. A central challenge for theoretical work is to relate, in a quantitatively controlled and unambiguous way, the observed jet quenching to fundamental properties of the QCD matter that induces them. I will give an introduction to the phenomenology and theoretical interpretation of jet quenching and discuss the recent attempt to describe the modification of jets based on perturbative QCD alone.
