In heavy-ion collisions, jets formed from hard-scattered partons experience an overall energy loss and have a modified internal structure compared to vacuum jets. These modifications are a result of the interactions between the energetic partons in a jet shower and the strongly coupled quark-gluon plasma (QGP). As the jet traverses the QGP, it loses momentum to the medium, which in turn...

The first measurement of the two-point energy correlator (EEC) in Pb-Pb collisions has revealed its sizeable modifications with respect to the p-p baseline. Nevertheless, challenges arise in comparing these measurements due to selection bias caused by energy loss, which leads to a shift in the Pb-Pb EEC spectrum toward smaller angles as compared to the p-p measurement. In this talk, we will...

We study the momentum broadening of a high energy quark jet in the high-density gluon medium created right after the collision of two ultrarrelativistic heavy nuclei, the Glasma. Previous Glasma studies consider the jet as a classical probe particle, for which position and momentum are simultaneously determined. In this talk, we use the light-front QCD Hamiltonian formalism to treat the jet...

Jet substructure is a powerful tool for testing QCD in elementary particle collisions. The two-point energy-energy correlator (EEC), defined as the energy-weighted cross section of particle pairs inside jets, is a novel jet substructure observable probing the correlation of energy flow within jets. In pp collisions, the angular dependence of the EEC cross section shows a distinct separation of...

In heavy-ion collisions, jets propagating through the quark-gluon plasma undergo interactions with the medium. These interactions modify the internal structure of jets, making jet substructure an invaluable tool for probing the microscopic properties of the QGP. N-point Energy Correlators, defined as energy-weighted N-particle correlations inside jets, have emerged as a novel substructure...

High-energy partons are known to lose energy when passing through the hot and dense medium produced in heavy-ion collisions. This energy loss depends on the mass, flavor of the fragmenting parton and on the structure of the partonic shower, providing valuable insights into the properties of the QCD medium. This talk presents new results from the ATLAS Collaboration, exploring the flavor...

In heavy-ion collisions, hard-scattered partons lose energy as they traverse the medium, which is simultaneously modified by this interaction. One expected medium modification, known as the "diffusion wake," is a particle enhancement in the direction of the parton and a depletion in the opposite direction. Although theoretically predicted, clear experimental evidence of the diffusion wake...
