Relativistic heavy ion collisions give an opportunity to study the structure of nuclear matter at extreme energy densities. High-resolution probes of this hot and dense nuclear matter are provided by jets (collimated sprays of energetic particles) that are produced in a process of hard parton-parton scattering. Interaction of a hard-scattered parton with the dense nuclear matter leads to a modification of the jet development with respect to the ‘vacuum’ case of proton-proton collisions, resulting in the phenomenon of jet quenching. ALICE, a dedicated heavy-ion experiment located at the Large Hadron Collider, pursues an extensive program of jet measurements. Recently, a number of fresh approaches to experimental studies of jet modification in heavy ion collisions were introduced. I will give some examples of those new ideas and their application to the data collected by ALICE, including jet-hadron correlations, jet mass measurements, and jet substructure studies. Besides discussing experimental results, I will talk about selected Monte Carlo models of jet quenching: what concepts underlie them and how well they describe the measurements.
