Description
Many model descriptions of the evolution of a heavy ion collision in Bjorken flow feature hydrodynamic attractor behaviour, referring to a quick memory loss mechanism and decay towards a universal time evolution curve that will itself converge to hydrodynamic behaviour. This has so far been observed in kinetic theory and in transient hydrodynamics. In both cases, at very early times, it is not the decay of transients but the strong longitudinal expansion that facilitates memory loss. However, this early time regime of heavy ion collisions features large gluonic occupation numbers and is best modeled by the semiclassical evolution of Yang-Mills fields, i.e. the Glasma. In this talk, I discuss to what extent hydrodynamic attractor behaviour is present in classical Yang-Mills dynamics.
