چکیده
D. BARNA for the NA49 Collaboration Central Research Institute for Physics, Konkoly-Thege út 29-33, H-1121, Budapest, Hungary In order to quantify isospin effects in the comparison of elementary to nuclear collisions, p-p and n-p interactions have been studied in the NA49 experiment in addition to p-Pb and PbPb reactions. Together with first measurements of cascade hyperon and Ω production in p-p collisions, isospin-corrected K/π ratios and cascade yields are discussed. The Ω + /Ω− ratio in p-p collisions is found to be less than 0.5 with 95% confidence level.

Strangeness production at SPS energies from NA49
We present results on strange particle production from experiment NA49 in central and minimum bias Pb+Pb collisions in the beam energy range 20A 158A GeV. New results on Ξ production in central Pb+Pb collisions and on Λ, Ξ production in minimum bias collisions are shown. Transverse mass spectra and rapidity distributions of strange particles at different energies are compared. The energy depend...

Recent NA49 results on Λ and φ production in central Pb-Pb collisions at beam energies from 40 to 158 A·GeV are presented. The measurement of strange baryons like Λ(uds), which contain between 30 and 60% of the total strangeness produced, allows to study simultaneously strangeness production and the effect of baryon density in A-A collisions. Essentially half of the ¯ s quarks are contained in ...

We present recent results of the SPS experiment NA49 on production of strange particles and event-by-event fluctuations of mean pt and of charged particle ratios in central Pb+Pb collisions at various beam energies (40, 80, 158 AGeV) as well as in different collisions at 158 AGeV, going from p+p over light-ion collisions to peripheral and central Pb+Pb.
