Particle Production from Sis to Sps Energies
The production and propagation of mesons (π, η, ρ, ω,Φ,K, K̄ , J/Ψ) in protonnucleus and nucleus-nucleus collisions from 1 200 GeV/u is studied within the covariant transport approach HSD, which explicitly allows to investigate selfenergy effects of the hadrons at finite baryon density. Whereas the experimental pion and K spectra can be described without introducing any selfenergies for the meso...
متن کاملBulk Hadron Production at AGS and SPS
With new data available from the SPS, at 40 and 80 GeV/A, I review the systematics of bulk hadron multiplicities, with prime focus on strangeness production. The classical concept of strangeness enhancement in central AA collisions is reviewed, in view of the statistical hadronization model which suggests to understand strangeness enhancement to arise chiefly in the transition from the canonica...
متن کاملCoulomb Effects in Charged Particle Spectra from Heavy Ion Collisions at AGS and SIS ∗
Data from the AGS experiment E866 on charged particles emitted in central Au+Au collisions at 10.8 AGeV incident energy is reviewed. The study of spectral shapes indicates the presence of collective transverse flow and – in particular for charged pions – of Coulomb final state interaction between emitted particles and the nuclear charge distribution. The comparison to SIS pion data measured wit...
متن کاملParticle Production and Flow at SIS Energies
An overview is given over recent measurement of flow and particle production in the energy range from 0.1 to 2AGeV. Excitation functions for the directed sideward and the azimuthally symmetric transverse flow are presented and show the importance of flow phenomena in this incident energy regime. Rapidity density distributions are indicative of a system size dependence of the stopping process. T...
متن کاملBaryon flow from SIS to AGS energies
We analyze the baryon sideward and elliptic flow from SIS (0.25 ∼ 2 AGeV) to AGS (2 ∼11.0AGeV) energies for Au + Au collisions in the relativistic transport model RBUU that includes all baryon resonances up to a mass of 2 GeV as well as string degrees of freedom for the higher mass continuum. There are two factors which dominantly determine the baryon flow at these energies: the momentum depend...
