$\Lambda$ and $\bar{\Lambda }$ Production in Central Pb-Pb Collisions at 40, 80, and 158 A$\cdot$GeV

The NA49 Collaboration, T. Anticic

Production of Lambda and Antilambda hyperons was measured in central Pb-Pb collisions at 40, 80, and 158 A$\cdot$GeV beam energy on a fixed target. Transverse mass spectra and rapi…
