Abstract.The time evolution of pseudorapidity distributions of produced charged hadrons in d + Au collisions at $ \sqrt{{s_{NN}}}$ = 200 GeV is investigated. Results of a nonequilibrium statistical relativistic diffusion model with three sources are compared with a macroscopic “bounce-back” model that does not allow for statistical equilibration at large times, but instead leads to motion reversal. When compared to the data, the results of the diffusion approach are more precise, thus emphasizing that the system is observed to be on its way to thermal equilibrium.
