TL;DR: In this article, the correlation of these produced particles with respect to the reaction plane was analyzed with the FOPI detector system, and it was shown that baryons exhibit a very pronounced sideward flow pattern which is qualitatively similar to the proton flow.

TL;DR: In this article, pions were measured with the 4π detector FOPI at GSI using the Au on Au reaction at 106 AGeV bombarding energy, and the average pion multiplicities per participant were #### and #### these values are only half as large as extrapolated from the low mass systems studied by Harris et al.

TL;DR: In this article, the scaling of the mean rapidity shift of protons established for between 10A and 200A GeV at the Brookhaven AGS and the CERN SPS accelerators energies is valid down to 1AGeV, and the degree of nuclear stopping is discussed; quantum molecular dynamics calculations reproduce the measured proton rapidity spectra for the most central events reasonably well.
