The Impact of Isospin Breaking on the Distribution of Transition Probabilities

C. I. Barbosa, T. Guhr, H. L. Harney

In the present paper we investigate the effect of symmetry breaking in the statistical distributions of reduced transition amplitudes and reduced transition probabilities. These qu…

Prompt Contributions to the Dilepton Yield in Heavy Ion Collisions

J. Huefner, Yu. P. Ivanov, B. Z. Kopeliovich +1

The mass spectrum is calculated for those dileptons which are produced in the early phase of a heavy ion collisions via the direct production NN -> (l^+)(l^-)X and via the Compton…

Unifying Nucleon and Quark Dynamics at Finite Baryon Number Density

J. Meyer, K. Schwenzer, H. -J. Pirner

We present a model of baryonic matter which contains free constituent quarks in addition to bound constituent quarks in nucleons. In addition to the common linear sigma-model we in…

Renormalization Group Flow Equation at Finite Density

J. Meyer, G. Papp, H. -J. Pirner +1

For the linear sigma model with quarks we derive renormalization group flow equations for finite temperature and finite baryon density using the heat kernel cutoff. At zero tempera…

Weak Interaction Rates Of sd-Shell Nuclei In Stellar Environment Calculated in the Proton-Neutron Quasiparticle Random Phase Approximation

J. -U. Nabi, H. V. Klapdor-Kleingrothaus

Allowed weak interaction rates for sd-shell nuclei in stellar environment are calculated using a generalized form of proton-neutron quasiparticle RPA model with separable Gamow-Tel…

Statistical Properties of Charmonium Spectrum and a New Mechanism of J/ψSuppression

Jianzhong Gu, Hongshi Zong, Yuxin Liu +1

The statistical properties of Charmonium energy spectrum determined by the Bethe-Salpeter equation are investigated. It is found that the regular motion of the system ca…

Relativistic description of J/ψdissociation in hot matter

H. S. Zong, J. Z. Gu, X. F. Zhang +2

The mass spectra and binding radii of heavy quark bound states are studied on the basis of the reduced Bethe-Salpeter equation. The critical values of screening masses for $c\bar{c…

Decay out of a Superdeformed Band

J. Z. Gu, H. A. Weidenmueller

Using a statistical model for the normally deformed states and for their coupling to a member of the superdeformed band, we calculate the ensemble average and the fluctuations of t…
