A systematic study of energy spectra for light particles emitted at midrapidity from Au + Au collisions at E = (0.25-1.15)A GeV reveals a significant nonthermal component consistent with a collective radial flow. This component is evaluated as a function of bombarding energy and event centrality. Comparisons to quantum molecular dynamics and Boltzmann-Uehling-Uhlenbeck models are made for different equations of state.

Abstract
A systematic study of energy spectra for light particles emitted at midrapidity from Au + Au collisions at E = (0.25-1.15)A GeV reveals a significant nonthermal component consistent with a collective radial flow. This component is evaluated as a function of bombarding energy and event centrality. Comparisons to quantum molecular dynamics and Boltzmann-Uehling-Uhlenbeck models are made for different equations of state.File in questo prodotto:
