Three-baryon collisions in BUU — •Alexei Larionov, Kai Gallmeister, and Ulrich Mosel — Institut für Theoretische Physik, Universität Giessen, Germany

In central heavy-ion collisions at the future FAIR energies (5 – 40 A GeV), the highest compression of the baryonic matter is expected. As a consequence, the role of the many-baryon collisions becomes quite important. In the present work we study the influence of three-baryon collisions on the transverse mass spectra of produced particles. The calculations are based on the GiBUU model. The kaon transverse mass spectra get significantly harder due to the three-baryon collisions, that explains the discrepancies between earlier calculations and experimental data.
