Various real-time observables, such as particle production rates from a hot medium, or "transport coefficients" (conductivities, viscosities), play an important role in all contexts in which relativistic thermal field theory is being applied. An example from heavy ion collisions could be the diffusion coefficient of heavy flavours, characterizing the efficiency at which "jets" containing a charm or bottom quark get "quenched"; an example from cosmology could be the production rate of right-handed neutrinos, playing an important role in many Dark Matter and Baryon Asymmetry computations. It is the strong interactions which play a crucial role in heavy ion collisions whereas in cosmology weak interactions are more prominent, yet both are described by non-Abelian gauge theories, so that on the technical side many of the methods used are similar. The goal of this project is to make progress towards a reliable determination of selected real-time observables playing a role in current heavy ion collision experiments as well as in certain cosmological scenarios, by making use of both analytic and numerical techniques.
