Abstract

The Omega-bar/Omega ratio originating from string decays is predicted to be larger than unity in proton-proton interaction at SPS energies. The anti-omega dominance increases with decreasing beam energy. This surprising behavior is caused by the combinatorics of quark-antiquark production in small and low-mass strings. Since this behavior is not found in a statistical description of hadron production in proton-proton collisions, it may serve as a key observable to probe the hadronization mechanism in such collisions., Comment: 10 pages, proceedings of the 18th International Winter Workshop on Nuclear Dynamics, Nassau, Bahamas, January 2002

Abstract

For central collisions Xe(50 A.MeV)+Sn we compared experimental data from the INDRA detector with QMD simulations. Theory as well as experiment show a clear binary character of the fragment emission even for very central collisions. From the time evolution of the reaction (QMD simulation) we could built up a scenario for the dynamical emission of fragments, Comment: To appear in the Proceedings of the 36th International Winter Meeting on Nuclear Physics, Bormio, Italy, Jan. 26-31 1998

Abstract

Recently it has been argued that the linear relation between the transverse energy and the apparent probability to emit a fragment proves that the total system is in thermal equilibrium. It is shown, for a specific reaction Xe+Sn at 50 A.MeV, that the same behavior is obtained in the context of Quantum Molecular Dynamical without invoking the idea of equilibrium. The linear dependance is shown to be a detector effect., Comment: 11 pages, 4 Postscript figures. Submitted Phys. Rev. Lett

Abstract

Electricité de France, the French electricity provider is moving into new markets, and needs to know very well its clients and tracks their satisfaction. Thus, different kinds of text mining tools were tested in order to analyze a huge quantity of heterogeneous textual documents, including mails, open-ended customer survey questions, discussion forums, and comments contained in large databases concerning customer contacts. In this context, it seemed unavoidable to build a test grid, in order to facilitate the comparison between different tools. This paper describes the test grid carrying out, the software selection, the way the evaluation of four tools (Alceste, SAS Text Miner, TEMIS Insight Discoverer and SPAD/CRM) was achieved and the results.

219. Chiral phase transition in an expanding quark antiquark plasma

Author

Abada, Abdellatif, Aichelin, Joerg, Abada, Abdellatif, and Aichelin, Joerg

Abstract

We investigate the time evolution of a quark antiquark plasma by solving numerically the relativistic transport equations derived on the Hartree level from the Nambu-Jona-Lasinio model. We find that the phase transition in the expanding quark antiquark plasma is different as compared to that in a static plasma. The expansion competes with the transition and finally quark droplets will be formed which subsequently hadronizes. These findings raise the question whether static thermal models can make at all any prediction about signals of that transition ., Comment: 7 pages, LaTeX file, 1 figure (not included, available on request).

225. Production of primordial J/ψ in relativistic p+p and heavy-ion collisions.

Abstract

J/ψ observables of p+p collisions at √s=200GeV and 2.76 TeV are calculated using the pythia event generator for the production of c and ¯c and the Wigner density formalism. The charm quark momentum from pythia is tuned in such a way that the transverse momentum and rapidity distribution correspond to the fixed-order next-to-leading logarithm calculations and hence to the experimental data for open charm mesons. Using the Wigner density of the charmonium wave function we calculate for each charm quark pair the probability to form a charmonium. As a result, the experimental data on the total J/ψ yield, its rapidity and transverse momentum distribution as well as the fractions of feed-down from excited states of charmonium are reproduced. Applying the same approach to relativistic heavy-ion collisions, we find, if quark gluon plasma (QGP) effects are ignored, a considerable enhancement of the primordial J/ψ's. [ABSTRACT FROM AUTHOR]

245. In-medium effects in strangeness production in heavy-ion collisions at (sub-) threshold energies.

Abstract

We study the in-medium effects in strangeness production in heavyion collisions at (sub-)threshold energies based on the microscopic Parton-Hadron-String Dynamics (PHSD) transport approach. The in-medium modifications of the antikaon properties are described via the self-consistent coupledchannel unitarized scheme based on a SU(3) chiral Lagrangian while the inmedium modification of kaons are accounted via the kaon-nuclear potential, which is assumed to be proportional to the local baryon density. We find that the modifications of (anti)kaon properties in nuclear matter are necessary to explain the experimental data in heavy-ion collisions. [ABSTRACT FROM AUTHOR]
