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 jet structure resulting from the interaction of high-energy quarks and gluons with the plasma. The ALICE detector’s excellent particle identification and tracking performances, down to low momentum in high-density environments, 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.
In this talk, I will present recent measurements of inclusive charged-particle jet yield modification in Pb-Pb collisions as well as semi-inclusive measurements of charged-particle jets recoiling from a trigger hadron. These measurements utilise novel data-driven statistical approaches to subtract the large uncorrelated background present in heavy-ion collisions. Comparison to state-of-the-art theoretical calculations incorporating jet quenching effects will also be discussed.
