On the Derivation of the Quantum Molecular Dynamics Approach
We investigate the formal structure of a quantal n -body theory. Employing a product ansatz and the impuls approximation we obtain a time evolution equation for the n - body system which contains only the meas...

How to extract the nuclear equation of state from heavy ion data
The Quantum Molecular Dynamic method is used to study the influence of the equation of state (EOS), in-medium n-n cross sections and momentum dependent interactions (MDI) on the main observables of heavy ion c...

Confrontation of Theoretical Approaches and Experimental Data on High Energy Heavy Ion Collisions
We give an overview of high energy heavy ion collisions. The merits and drawbacks of macroscopic and microscopic theoretical approaches (Fluid Dynamics, TDHF, Cascade, Vlasov-Uehling-Uhlenbeck, Classical and Q...

Hadron production ine +e− annihilation and μ-p collisions under the assumption of longitudinal phase space dominance
Rapidity and multiplicity distributions are calculated for the hadrons produced ine +e− annihilation and deep inelastic muon-proton collisions for c.m. energies of 10 to 40 GeV. The hypothesis of longitudinal pha...

Microscopic calculation of pion production in nucleus-nucleus collisions around 1 GeV·A
The pion production cross section in nucleus-nucleus collisions at aboutE lab/A=1 GeV is calculated within the relativistic (RQMD) and the nonrelativistic quantum molecular dynamics (QMD) approach. We use both so...

Nucleonic Flow, Kaon Production and the Nuclear Equation of State
A major goal of studying heavy ion reactions is the unique opportunity to create hot and dense nuclear matter in the laboratory.1 Unfortunately, this novel state of nuclear matter exists only for a very short tim...

Studies on the timescale of fragment formation in heavy ion collisions
Why does a nucleus shatter into to several (up to a dozen) intermediate mass fragments (IMF’s) if hit by a projectile nucleus? Is this only a statistical process and hence microcanonical phase space models are...

Modelling the many-body dynamics of heavy ion collisions: Present status and future perspective
Basic problems of the semiclassical microscopic modelling of strongly interacting systems are discussed within the framework of Quantum Molecular Dynamics (QMD). This model allows to study the influence of se...

Charmonium cross section from p—A production
Several extractions of the ϕ-N cross section from ϕ production in γ+A and h+A reactions have been attempted. We discuss these and the issue of charmonium formation using the recent data obtained by E866/NuSea.

Strange baryons in a hot and dense medium within the Nambu-Jona-Lasinio model
The understanding of the chiral phase transition is one of the challenges of present day nuclear physics. Lattice gauge calculation are still not advanced enough to provide reliable information on how this tra...

Origin of Fragments in Multifragmentation Reactions
Using the quantum molecular dynamics approach we have started to analyze the results of the recent INDRA experiments at GSI experiments. For the first time we could identify a midrapidity source in which fragm...

Thermalization at lowest energies? A view from a transport model
Using the Isospin Quantum Molecular Dynamics (IQMD) model we analyzed the production of pions and kaons in the energy range of 1–2 A GeV in order to study the question why thermal models could achieve a successfu...

K − and \(\bar p\) spectra for AuAu collisions at \(\sqrt s = 200\) GeV from STAR, PHENIX, and BRAHMS in comparison to core-corona model predictions
Based on results obtained with event generators we have launched the core-corona model. It describes in a simplified way but quite successfully the centrality dependence of multiplicity and 〈p ...

Energy Loss of Heavy Quarks—A Signal of Plasma Properties
The possible observables for studying the properties of a plasma of quarks and gluons (QGP), which is presumably created in ultrarelativistic heavy-ion collisions, are discussed. While the light mesons do not ...

On the mass dependence of the energy of vanishing flow for superheavy mass region
Using the isospin-dependent quantum molecular dynamics model, we predict the energy of vanishing flow in the superheavy mass region. Our calculations show significant deviations from the power law mass depende...

Degrees of Freedom of the Quark Gluon Plasma, Tested by Heavy Mesons
Heavy quarks (charm and bottoms) are one of the few probes which are sensitive to the degrees of freedom of a Quark Gluon Plasma (QGP), which cannot be revealed by lattice gauge calculations in equilibrium. Du...
