Strange and Non-Strange (Anti-)Baryon Production at 200 GeV per Nucleon

Abstract

Rapidity distributions of net hyperons ($\Lambda -\overline{\Lambda }$) are compared to distributions of participant protons ($p-\overline{p}$). Strangeness production (mean multiplicities of produced $\Lambda /{\Sigma }^0$ hyperons and $⟨K+\overline{K}⟩$) in central nucleus-nucleus collisions is shown for different collision systems at different energies. An enhanced production of $\overline{\Lambda }$ compared to $\overline{p}$ is observed at 200 GeV per nucleon.
