Heavy-ion collisions and the quark gluon plasma

talk (30min)

Jet quenching - the modification of high-energy jets in the quark-gluon plasma - has been extensively studied through weakly coupled scattering amplitudes embedded in parton-shower frameworks. These models, often combined with bulk hydrodynamic evolution, successfully describe a wide range of observables, though they typically rely on assumptions of rapid thermalization and simplified...

Heavy-ion collisions and the quark gluon plasma

talk (30min)

One of the central open questions in heavy-ion collisions is how the initially far-from-equilibrium plasma of deconfined quarks and gluons evolves toward local thermal equilibrium, a process known as hydrodynamization. Despite its importance, direct experimental signatures of this early pre-equilibrium stage remain elusive. Hard probes, such as jets, produced at very early times, offer a...

Heavy-ion collisions and the quark gluon plasma

talk (15min)

High-energy partons traversing the quark-gluon plasma (QGP) lose energy primarily through splittings induced by interactions with the medium. These processes have been studied extensively in different approximations, often assuming a near-equilibrium medium background. However, in realistic heavy-ion collisions, the QGP starts far from equilibrium and undergoes an expansion and thermalization...

Heavy-ion collisions and the quark gluon plasma

talk (15min)

Heavy quarks are usually modeled as Brownian probes of the quark-gluon plasma, with momentum exchange encoded by drag and Gaussian diffusion. Recent weak- and strong-coupling results show that this diffusion truncation misses a robust feature of real-time heavy-quark dynamics: the longitudinal momentum-transfer distribution has a Gaussian core but asymmetric exponential tails. These tails are...
