Progress in Collective Flow Studies from the Onset to Bevalac/SIS

“…Thus, a clearer and more complete understanding of some flow systematics is emerging from the new flow studies. Further, this new finding validates the use of one-body models that lack composite cluster formation, such as the BUU, in the study of flow physics [6].…”

“…Comparative studies (see, e.g. [6]) of early sidewards flow measurements with theoretical predictions proved unable to extract definitively the nuclear EOS. Ambiguities arose from both experimental and theoretical uncertainty.…”

Semiclassical Methods of Deformation Quantisation in Transport Theory

“…Due to technical peculiarities of processor manufacturing, this regime is expected to continue for 5 -15 years. The theoretical foundations of the transport models used to simulate heavy-ion collisions were created in the late 1980s -early 1990s (Sorge et al, 1989;Aichelin, 1991;Faessler, 1992; www.intechopen.com Blaettel et al, 1993). Many uncertainties exist in the estimates of the times of the simulations.…”

Heavy Ion Collisions at Relativistic Energies: Testing a Nuclear Matter at High Baryon and Isospin Density

“…For the description of heavy ion collisions we solve the covariant transport equation of the Boltzmann type [ 4,5] within the Relativistic Landau Vlasov (RLV ) method, using phase-space Gaussian test particles [ 8], and applying a Monte-Carlo procedure for the hard hadron collisions. The collision term includes elastic and inelastic processes involving the production/absorption of the ∆(1232MeV ) and N * (1440MeV ) resonances as well as their decays into pion channels, [ 9].…”

“…Here we focus our attention on relativistic heavy ion collisions, that provide a unique terrestrial opportunity to probe the in-medium nuclear interaction in high density and high momentum regions. An effective Lagrangian approach to the hadron interacting system is extended to the isospin degree of freedom: within the same frame equilibrium properties (EoS, [ 3]) and transport dynamics [ 4,5] can be consistently derived.…”
