Abstract
We present a summary of measurements of strange particles performed by the experiment
NA49 in central and minimum bias Pb+Pb collisions in the beam energy range 20A - 158A
GeV. New results on Xi production in central Pb+Pb collisions and on Lambda, Xi production
in minimum bias collisions are shown. Transverse mass spectra and rapidity distributions
of strange particles at different energies are compared. The energy dependence of
the particle yields and ratios is discussed. NA49 measurements of the Lambda and Xi
enhancement factors are shown for the first time.
