Nuclear Experiment - Abstract
The measurement of production of Lambda and Antilambda hyperons was taken in central Pb-Pb collisions at 40, 80, and 158A GeV beam energy on a fixed target. For all the three beam energies the transverse mass spectra and rapidity distributions are studied. By integrating the rapidity spectra with extrapolations into unmeasured regions, total multiplicities were obtained. The ratio of the three energies at midrapidity and in full phase space was also studied.
