Jet substructure measurements at ALICE
Leticia Cunqueiro, for the ALICE Collaboration
The yields and fragmentation pattern of jets are modified by the dense medium created in heavy ion collisions relative to proton proton collisions. The main scope of the jet program in heavy ions is to address those modifications, relate them to specific aspects of the dynamics of the jet-medium interactions and to extract a microscopic description of the medium.
Techniques like grooming, iterative de-clustering and mapping the jet tree branches onto Lund maps can help to individuate regions of phase space dominated by the different components of the experimental background and expected signal, such as combinatorial background, medium response, vacuum radiation, multiple soft or semi-hard medium-induced radiation. We will discuss recent jet substructure measurements in Pb-Pb collisions at ALICE.
