Lambda production in central Pb+Pb collisions at CERN-SPS energies
- In this paper we present recent results from the NA49 experiment for Lambda and Lambda hyperons produced in central Pb+Pb collisions at 40, 80 and 158 A GeV. Transverse mass spectra and rapidity distributions for Lambda are shown for all three energies. The shape of the rapidity distribution becomes flatter with increasing beam energy. The multiplicities at mid-rapidity as well as the total yields are studied as a function of collision energy including AGS measurements. The ratio Lambda/pi at mid-rapidity and in 4 pi has a maximum around 40 A GeV. In addition, Lambda rapidity distributions have been measured at 40 and 80 A GeV, which allows to study the Lambda Lambda ratio.
