Strangeness in Relativistic Astrophysics
Jurgen Schaffner-Bielich, Stefan Schramm, Horst Stocker
In these lecture notes, the role of strangeness in relativistic astrophysics of compact stars is addressed. The appearance of strange particles, as hyperons, kaons, and strange qua…
Effects of Strong Color Fields on Baryon Dynamics
Sven Soff, Jorgen Randrup, Horst Stocker +1
We calculate the antibaryon-to-baryon ratios, anti-p/p, anti-Lambda/Lambda, anti-Xi/Xi, and anti-Omega/Omega for Au+Au collisions at RHIC (sqrt{s}_{NN}=200 GeV). The effects of str…
Phase Transition to Hyperon Matter in Neutron Stars
Jurgen Schaffner-Bielich, Matthias Hanauske, Horst Stocker +1
Recent progress in the understanding of the high density phase of neutron stars advances the view that a substantial fraction of the matter consists of hyperons. The possible impac…
Constraints on models for the initial collision geometry in ultra relativistic heavy ion collisions
Roy A. Lacey, Rui Wei, N. N. Ajitanand +6
Monte Carlo (MC) simulations are used to compute the centrality dependence of the collision zone eccentricities (), for both spherical and deformed ground state nuclei, f…
Phi-Meson Production at RHIC, Strong Color Fields and Intrinsic Transverse Momenta
Sven Soff, Srikumar Kesavan, Jorgen Randrup +2
We investigate the effects of strong color fields and of the associated enhanced intrinsic transverse momenta on the phi-meson production in ultrarelativistic heavy ion collisions…
Has the QCD Critical Point been Signaled by Observations at RHIC ?
Roy A. Lacey, N. N. Ajitanand, J. M. Alexander +6
The shear viscosity to entropy ratio () is estimated for the hot and dense QCD matter created in Au+Au collisions at RHIC ( GeV). A very low value is found…
