| Jets during the nonequilibrium QCD plasma in heavy-ion collisions: Broadening and gluon radiation |
| Speaker: | Florian Lindenbauer (MIT) |
| Abstract: | Relativistic heavy-ion collisions create a plasma of deconfined quarks
and gluons, which is initially far from equilibrium. While most studies
describe this plasma as a relativistic fluid, this approximation is not
valid at early times, where QCD kinetic theory can be used to model the
nonequilibrium plasma dynamics. In this talk, I will discuss how this
nonequilibrium plasma influences the propagation of energetic particles,
which are then measured as jets in the detectors. In particular, I will
discuss how their momentum broadening is modified in the presence of a
nonequilibrium and anisotropic QCD medium, and how the resulting emitted
gluon spectrum differs from equilibrium. These results establish a basis
for incorporating nonequilibrium dynamics into realistic descriptions of
jet quenching and the evolution of hard probes. |
