Particle 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 at Sis Energies *
We calculate the baryon flow 〈Px/A(y)〉 in the energy range from .25 to ≤2.5AGeV in a relativistic transport model for Ni + Ni and Au+Au collisions employing various models for the baryon self energies. We find that to describe the flow data of the FOPI Collaboration the strength of the vector potential has to be reduced at high relative momentum or at high density such that the Schrödingerequiv...
متن کاملDilepton production at SIS energies
In this short review the results of detailed studies for dilepton production from p + A and A + A reactions at SIS energies are presented. The calculations are based on a semi-classical BUU transport model that includes the off-shell propagation of vector mesons and evaluates the width of the vector mesons dynamically. Different scenarios of in-medium modifications of vector mesons, such as col...
متن کاملParticle 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 کاملKaon versus Antikaon Production at SIS Energies∗
We analyse the production and propagation of kaons and antikaons in Ni + Ni reactions from 0.8–1.85 GeV/u within a coupled channel transport approach including the channels BB → K+Y N, πB → K+Y, BB → NNKK̄, πB → NKK̄, KB → KB, K̄B → K̄B, Y N → K̄NN, ππ → KK̄ as well as πY → K̄N and K̄N → πY for the antikaon absorption. Whereas the experimental K+ spectra can be reproduced without introducing any selfen...
