QCD Jet Dynamics and the Time Evolution of the Quark-Gluon Plasma

Ultra-relativistic heavy-ion collisions recreate conditions similar to the early Universe, allowing for the brief formation of the Quark-Gluon Plasma (QGP), a high-temperature and high-density phase of QCD matter. Due to its short lifetime, QGP properties are challenging to observe directly, requiring indirect probing methods. Jets, which emerge from the fragmentation of hard-scattered partons, provide a valuable tool for probing the QGP across a wide range of scales. As jets propagate through the plasma, their interactions with the medium are influenced by its evolving characteristics. These jet-medium interactions offer new perspectives on the temporal evolution of the QGP and open a novel pathway to explore the time structure of QCD radiation. This seminar will focus on how jets, as dynamic probes, can help reveal the interplay between the QGP and high-energy QCD.
