Constraints on models for the initial collision geometry in ultra relativistic heavy ion collisions

Autor: Lacey, Roy A., Wei, Rui, Ajitanand, N. N., Alexander, J. M., Gong, X., Jia, J., Taranenko, A., Pak, R., Stocker, Horst

Publikováno v: Phys.Rev.C81:061901,2010

Monte Carlo (MC) simulations are used to compute the centrality dependence of the collision zone eccentricities ($\epsilon_{2,4}$), for both spherical and deformed ground state nuclei, for different model scenarios. Sizable model dependent difference

Strangeness in Relativistic Astrophysics

Autor: Schaffner-Bielich, Jurgen, Schramm, Stefan, Stocker, Horst

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 quarks, in the core of compact stars is examined and common features as w

Report

Has the QCD Critical Point been Signaled by Observations at RHIC ?

Autor: Lacey, Roy A., Ajitanand, N. N., Alexander, J. M., Chung, P., Holzmann, W. G., Issah, M., Taranenko, A., Danielewicz, P., Stocker, Horst

Publikováno v: Phys.Rev.Lett.98:092301,2007

The shear viscosity to entropy ratio ($\eta/s$) is estimated for the hot and dense QCD matter created in Au+Au collisions at RHIC ($\sqrt{s_{NN}}=200$ GeV). A very low value is found $\eta/s \sim 0.1$, which is close to the conjectured lower bound ($

Multifragmentation, Clustering, and Coalescence in Nuclear Collisions

Autor: Scherer, Stefan, Stocker, Horst

Publikováno v: Proceedings of the International Symposium "Atomic Cluster Collisions", St. Petersburg, Russia, July 18-21, 2003; edited by J.-P. Connerade and A.V. Solov'yov; London, 2004; 169-180

Nuclear collisions at intermediate, relativistic, and ultra-relativistic energies offer unique opportunities to study in detail manifold fragmentation and clustering phenomena in dense nuclear matter. At intermediate energies, the well known processe

Phi-Meson Production at RHIC, Strong Color Fields and Intrinsic Transverse Momenta

Autor: Soff, Sven, Kesavan, Srikumar, Randrup, Jorgen, Stocker, Horst, Xu, Nu

Publikováno v: J.Phys. G30 (2004) L35-L42

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 at RHIC. The observed consequences include a change of the spectral sl

Effects of Strong Color Fields on Baryon Dynamics

Autor: Soff, Sven, Randrup, Jorgen, Stocker, Horst, Xu, Nu

Publikováno v: Phys.Lett.B551:115-120,2003

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 strong color fields associated with an enhanced strangeness and diquark p

Phase Transition to Hyperon Matter in Neutron Stars

Autor: Schaffner-Bielich, Jurgen, Hanauske, Matthias, Stocker, Horst, Greiner, Walter

Publikováno v: Phys.Rev.Lett.89:171101,2002

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 impacts of a highly attractive interaction between hyperons on the properti
