Kinetic-model description of collective effects in heavy-ion collisions: transverse momentum, stopping, and flow

Abstract

Symmetric intermediate-energy heavy-ion collisions are studied in the Boltzmann-Nordheim-Vlasov theory, where the collision dynamics is determined by the mean field, the Pauli principle, and the NN scattering cross sections. Differences between the parallel-ensemble and full-ensemble approaches are enumerated. The effect of the model equation of state on the transverse momentum transfer is delineated and shown to be dramatically energy dependent. The mass dependence of the transverse momentum transfer, rapidity distribution, and collective flow angle is discussed.
