A main difficulty in understanding the dynamics of jets produced in the high-density environment of ultrarelativistic heavy ion collision, is to provide a unified description for the two sources of radiation that are a priori expected: the "vacuum-like" emissions responsible for the parton shower from large virtualities (of the order of the hard scale) down to the hadronisation scale and the...
Abstract: In this talk, we present the latest measurements of the jet fragmentation and the angular distributions of charged particles within and around jets, as performed with the ATLAS detector in Pb+Pb collisions at the LHC. Jets are direct probes of the QCD medium created in these collisions, and studying jet fragmentation provides insight into the strength and mechanism of jet quenching....
Recent results in jet substructure measurements in pp and Pb--Pb collisions are presented at $\sqrt{s} = 7$ TeV and $\sqrt{s_{\rm NN}}= 2.76$ TeV respectively. The jet shapes discussed focus on the splitting process of jets either by quantifying the 2-prongness of the jet (τ2/τ1) or by parameterising the splitting process itself (zg and Rg). The Nsubjettiness of a jet could be sensitive to a...
We present recent results on measurements of inclusive jet substructures using grooming techniques and constituent correlations with pp and PbPb data collected with the CMS detector at a center-of-mass energy of 5.02 TeV per nucleon pair. Jet grooming techniques are used to focus on the hard structure of the jet by extracting the two subjets corresponding to the hardest parton splitting. The...
