Strangeness Production close to Threshold in Proton-Nucleus and Heavy-Ion Collisions
Christoph Hartnack, Helmut Oeschler, Yvonne Leifels +2
We discuss strangeness production close to threshold in p+A and A+A collision. Comparing the body of available K+, K0, K-, and Lambda data with the IQMD transport code and for some…
How to determine experimentally the K+ nucleus potential and the K+ N rescattering cross section in a hadronic environment?
C. Hartnack, A. Sood, H. Oeschler +1
Comparing K+ spectra at low transverse momenta for different symmetric collision systems at beam energies around 1 AGeV allows for a direct determination of both the strength of th…
Thermalization at lowest energies? A view from a transport model
C Hartnack, H Oeschler, J Aichelin
Using the Isospin Quantum Molecular Dynamics (IQMD) model we analyzed the production of pions and kaons in the energy range of 1-2 AGeV in order to study the question why thermal m…
Kaon production at subthreshold energies - what do we learn about the nuclear medium ?
C Hartnack, H Oeschler, J Aichelin
The Isospin Quantum Molecular Dynamics model is used to compare spectra and elliptic flow of kaons produced at subthreshold energies with data taken at the SIS accelerator at GSI.…
Transition from Baryon- to Meson-Dominated Freeze Out -- Early Decoupling around 30 A GeV?
H. Oeschler, J. Cleymans, K. Redlich +1
The recently discovered sharp peak in the excitation function of the K+/pi+ ratio around 30 A GeV in relativistic heavy-ion collisions is discussed in the framework of the Statisti…
Recent astrophysical and accelerator based results on the Hadronic Equation of State
Ch. Hartnack, H. Oeschler, Jörg Aichelin
In astrophysics as well as in hadron physics progress has recently been made on the determination of the hadronic equation of state (EOS) of compressed matter. The results are cont…
