Abstract: 
Aiming at a microscopic description of heavy ion collisions in the beam energy region of about 10A GeV, we extend the Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) transport model by including a relativistic mean field, in-medium baryon-baryon cross sections, and three-body collisions. The model is then compared with experimental data for central Au+Au collisions at 2A-10A GeV and central Pb+Pb collisions at 30A and 40A GeV on the proton rapidity spectra, the midrapidity yields of pi(+),K-+/-, and (Lambda+Sigma(0)), and the transverse mass spectra of pi(+/-) and K-+/-. The three-body collisions increase the inverse slope parameters of the hadron m(perpendicular to) spectra to good agreement with the data.
