Strangeness Dynamics in Relativistic Nucleus-nucleus Collisions *
We investigate hadron production as well as transverse hadron spectra in nucleus-nucleus collisions from 2 A·GeV to 21.3 A·TeV within two independent transport approaches (UrQMD and HSD) that are based on quark, diquark, string and hadronic degrees of freedom. The comparison to experimental data demonstrates that both approaches agree quite well with each other and with the experimental data on...
متن کاملStrangeness Production in Relativistic Heavy Ion Collisions
The aim of the experimental program of relativistic heavy ion collisions is to the study nuclear matter under extreme conditions of temperature and energy density. In order to achieve this goal, is necessary to understand the dynamics of such collisions. The most striking feature of relativistic heavy ion collisions is the copious production of particles of a great variety of species. The compr...
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–...
متن کاملTransverse Pressure and Strangeness Dynamics in Relativistic Heavy Ion Reactions
Transverse hadron spectra from proton-proton, proton-nucleus and nucleus-nucleus collisions from 2 AGeV to 21.3 ATeV are investigated within two independent transport approaches (HSD and UrQMD). For central Au+Au (Pb+Pb) collisions at energies above Elab ∼ 5 AGeV, the measured K transverse mass spectra have a larger inverse slope parameter than expected from the default calculations. The additi...
متن کاملStrangeness in Ultrarelativistic Nuclear Collisions
Production of strangeness was among the first observables studied in ultrarelativistic nuclear collisions in the search for quark-gluon plasma (QGP). The transition into plasma phase was expected to facilitate strangeness production and lead to its enhanced abundance [1]. It is namely rather costly to produce strangeness in a hadronic system; the lowest threshold which is about 530 MeV above th...
