We study the spectral properties of a highly occupied non-Abelian non-equilibrium plasma that is expected to be created during the initial stages of heavy-ion collisions in the weak-coupling description of the collisions. The spectral function of this far-from-equilibrium plasma is measured by employing linear response theory in classical-statistical real-time lattice Yang-Mills simulations....

We investigate the radiative break-up highly energetic quark and gluon jets due to medium-induced Bremsstrahlung in a high-temperature plasma. We find that within an inertial range of momenta T << p << E, where E denotes the energy of the jet and T the temperature of of the medium, the quark/gluon ratio of fragments is identical for quark and gluon jets and approximately given by the ratio of...

We present a relativistic causal description of conserved-charge diffusion for heavy-ion collisions and show that it produces measurable effects in observables such as the charge balance functions. Other descriptions, based on ordinary diffusion, are known to produce charge fluctuations which propagate with infinite velocity, thus violating a fundamental postulate of special relativity. We...
