We compare multiplicities as well as rapidity and transverse momentum distributions of protons, pions and kaons calculated within presently available transport approaches for heavy-ion collisions around 1 A GeV. For this purpose, three reactions have been selected: Au+Au at 1 and 1.48 A GeV and Ni+Ni at 1.93 A GeV.

Subthreshold

Within a BUU type transport model we study Φ meson production in subthreshold Ni + Ni and Ru + Ru reactions. For the first time we included in our model the elementary reaction channels ρ + N, Δ → Φ + N, π + N((1520) → Φ + N and πρ → Φ. In spite of a substantial increase of the Φ multiplicities by these channels, our results stay significantly below the preliminary experimental data.Within a BUU type transport model we study
