Resonance production at SPS energies: CERES and NA49
We present results on resonance production by the NA49 and CERES collaborations. The measurement of the differential yields and spectral distributions of the K∗(892), Δ(1232), ρ, φ and Λ(1520) resonances from their leptonic and hadronic decay channels at different C.M.S. energies and for various colliding systems allows us to study in-medium modifications of the resonance mass, width and yield ...
متن کاملStrangeness 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...

متن کاملBaryon stopping and strange baryon / antibaryon production at SPS energies
The amount of proton stopping in central P b + P b collisions from 20 – 160 A·GeV as well as hyperon and antihyperon rapidity distributions are calculated within the UrQMD model in comparison to experimental data at 40, 80 and 160 A·GeV taken recently from the NA49 collaboration. Furthermore , the amount of baryon stopping at 160 A·GeV for P b + P b collisions is studied as a function of centra...
متن کاملEnergy and rapidity dependence of electric charge correlations at 20-158GeV beam energies at the CERN SPS (NA49)
Electric charge correlations are studied with the Balance Function method for central Pb + Pb collisions at the CERN SPS. The results on centrality selected Pb + Pb interactions at 40 and 158 AGeV are presented for the first time for two different rapidity intervals. In the mid-rapidity region a decrease of the width with increasing centrality of the collision is observed whereas in the forward...
