Description

One of the big uncertainties in extracting the transport coefficients by comparing the experimental data from A+A or p+A collisions to the results from relativistic dissipative fluid dynamics is the applicability of fluid dynamics in describing the evolution of such small systems. We investigate the applicability of fluid dynamics by comparing fluid-dynamical calculations to the solutions of the Boltzmann equation. We study several different systems by varying the system size and the underlying microscopic cross section. In particular, we analyze the space-time evolution of the energy density, number density, and velocity fields. Furthermore, we investigate different freeze-out conditions and the applicability of fluid dynamics, with dissipative corrections to the particle distribution function at freeze-out, in describing the final particle spectra and flow coefficients in p+p, p+A and A+A collisions.
