Description
The ALICE experiment at the LHC is focused on the investigation of the Quark-Gluon Plasma (QGP), a fundamental state of matter at high temperature in which quarks and gluons are deconfined, and which is generated in heavy-ion collisions at ultra-relativistic energies. One of the key experimental signatures to explore the structure and dynamics of the QGP is ‘jet quenching’, the modification of the jet structure resulting from the interaction of high-energy quarks and gluons with the plasma. In this talk I will discuss recent ALICE measurements of jet quenching which utilise excellent particle tracking down to low momentum in high-density environments. These capabilities enable jet-quenching measurements over a very broad phase space, including low-energy and large-radius jets that are seen to be strongly modified, providing a window into the response of the QGP to excitations. ALICE particle-identification capabilities also provide the unique opportunity to use jet hadrochemistry as a differential probe of jet-medium interactions at the LHC.
