$\Xi$ and $\overline{\Xi}$ production in 158 GeV/nucleon Pb + Pb collisions

We report measurements of $\Xi$ and $\bar{\Xi}$ hyperon absolute yields as a function of rapidity in 158 GeV/c Pb+Pb collisions. At midrapidity, dN/dy = 2.29 +/- 0.12 for $\Xi$, and 0.52 +/- 0.05 for $\bar{\Xi}$, leading to the ratio of $\bar{\Xi}$/$\Xi$ = 0.23 +/- 0.03. Inverse slope parameters fit...
