Nuclear Theory Seminar - Stefan Floerchinger (CERN), "Mode-by-mode fluid dynamics for relativistic heavy ion collisions"

Initial fluctuations in hydrodynamic fields such as energy density, flow velocity or shear stress provide an interesting chance to better understand initial state and equilibration physics as well as thermodynamic and transport properties. We use a mode resolved description with a background-fluctuation splitting and a Bessel-Fourier expansion for the fluctuating fields for a complete characterization of initial conditions, the fluid dynamical propagation of single modes, the study of interaction effects between modes, the determination of the associated particle spectra and the generalization of the whole program to event-by-event correlations and probability distributions.
