Strange Baryon Production From Nucleus-Nucleus Collisions at the AGS, SPS and RHIC
نویسنده
چکیده
We will present a review of selected results on strange baryon production from nucleus-nucleus collisions at the AGS, SPS and RHIC. From the AGS and SPS heavy ion physics program several intriguing aspects: centrality dependence of strangeness production, anti-hyperon yield, hyperon production enhancement and baryon number transport will be highlighted. Our discussion on RHIC results will focus on experimental probes of partonic degree of freedom. Measurements of the elliptic flow v2 and the nuclear modification factor and their distinctive particle dependence are presented as a function of transverse momentum.

We report on measurements of identified particle yields from Au-Au collisions at √ s N N = 62.4 GeV made with the BRAHMS spectrometer. Here we will concentrate on the charged K/π ratios as function of rapidity and baryo-chemical potential. We find that the K/π ratios measured at different rapidities in the analysed dataset have a common dependence with the same ratios measured in mid-rapidity a...
متن کاملResonances from PHSD
The multi-strange baryon and vector meson resonance production in relativistic nucleus-nucleus collisions is studied within the parton-hadronstring dynamics (PHSD) approach which incorporates explicit partonic degreesof-freedom in terms of strongly interacting quasiparticles (quarks and gluons) in line with an equation-of-state from lattice QCD as well as the dynamical hadronization and hadroni...
متن کاملStrangeness in Nuclear Collisions
Data on the mean multiplicity of strange hadrons produced in minimum bias proton– proton and central nucleus–nucleus collisions at momenta between 2.8 and 400 GeV/c per nucleon have been compiled. The multiplicities for nucleon–nucleon interactions were constructed. The ratios of strange particle multiplicity to participant nucleon as well as to pion multiplicity are larger for central nucleus–...

In my talk I want to introduce the thermodynamical analysis of data from (ultrarelativistic)nucleus-nucleus collisions at AGS, SPS and RHIC. A simple thermodynamical model can beused to determine the temperature T and the Baryon chemical potential μB at freeze-outfrom Quark Gluon Plasma to a free Hadron gas. This phase boundary can be investigated byscanning the beam energy ...
متن کاملRapidity losses in heavy-ion collisions from AGS to RHIC energies
We study the rapidity losses in central heavy-ion collisions from AGS to RHIC energies with the mean rapidity determined from the projectile net-baryon distribution after collisions. The projectile net-baryon distribution in the full rapidity range was obtained by removing the target contribution phenomenologically at forward rapidity region from the experimental net-baryon measurements and tak...
