Jets in ultrarelativistic heavy ion collisions: a tale of two cascades
There are spectacular experimental evidences from the LHC that jets produced in high energy nucleus-nucleus collisions are strongly affected by their propagation through matter. Simple arguments, based on Quantum Chromodynamics, lead us indeed to expect that the pattern of radiations emitted by an energetic parton travelling through a medium is very different from that of a parton propagating in vacuum after a hard collision. For instance, the cascade of gluons emitted in medium exhibit interesting features, akin to wave turbulence. In this talk, I shall review some of these features, and indicate why they could be relevant for the interpretation of LHC data.
