We investigate the properties of hadronic matter and nuclei be means of a generalized $SU(3)\times SU(3)$ $\sigma$ model with broken scale invariance. In mean-field approximation, vector and scalar interactions yield a saturating nuclear equation of

Publikováno v: Acta Physica Hungarica A) Heavy Ion Physics. 21:151-156

The measured particle ratios in central heavy-ion collisions are investigated within a chemical and thermal equilibrium chiral SU(3) σ−ω approach. Contrary to the commonly adopted non-interacting gas calculations, the chiral SU(3) model predicts

Rotating neutron stars in a chiralSU(3) model

Autor: S. Schramm, D. Zschiesche

Publikováno v: Journal of Physics G: Nuclear and Particle Physics. 29:531-542

We study the properties of rotating neutron stars within a generalized chiral SU(3)-flavor model. The influence of the rotation on the inner structure and the hyperon matter content of the star is discussed. We calculate the Kepler frequency and mome

Critical review of quark gluon plasma signals

Compelling evidence for a new form of matter has been claimed to be formed in Pb+Pb collisions at SPS. We critically review two suggested signatures for this new state of matter: First the suppression of the J/$\Psi$, which should be strongly suppres
