Findings

Parton energy loss mechanisms are crucial for understanding jet modification.

Experimental observables include hadron production and full jet measurements.

Jet quenching provides insights into the properties of the quark-gluon plasma.

Abstract

High energy quarks and gluons play essential roles in the tomographic study of relativistic heavy-ion collisions and of the quark-gluon plasma. They interact with the traversed dense matter through elastic and inelastic collisions, and lose some of their initial energy in the process. Experimental observables for jet modification include single inclusive hadron production, hadron emission opposite to a triggered hadron or photon, and full jet observables. Here a brief review of parton energy loss and jet quenching in high energy nucleus-nucleus collisions is presented.
