The Two-Pion Exchange NN-Potential in Nuclear Matter and Nuclear Stability
R. Rapp, J. W. Durso, J. Wambach
A meson exchange model of the interaction which fits free scattering data is used to calculate the interactions of pions in nuclear matter as a function of nuclear densit…
The Linear Sigma-Model in the 1/N-Expansion via Dynamical Boson Mappings and Applications to -Scattering
Z. Aouissat, P. Schuck, J. Wambach
We present a non-perturbative method for the study of the O(N+1)-version of the linear sigma-model. Using boson-mapping techniques, in close analogy to those well-known for fermion…
The quark condensate at finite temperature
G. Chanfray, M. Ericson, J. Wambach
The temperature evolution of the quark condensate is studied using three different methods. In the spirit of a many-body approach we make an expansion in the scalar density up to s…
Quenching of excitations in the double giant resonance
C. A. Bertulani, V. Yu. Ponomarev, V. V. Voronov
The electromagnetic excitation of the two-phonon isovector giant dipole resonance in relativistic projectiles incident on heavy targets can be proceed via several intermediate $1^-…
A Non-Perturbative Treatment of the Pion in the Linear Sigma-Model
Z. Aouissat, G. Chanfray, P. Schuck +1
Using a non-perturbative method based on the selfconsistent Quasi-particle Random-Phase Approximation (QRPA) we describe the properties of the pion in the linear -model. It is f…
Oscillations of the static meson fields at finite baryon density
W. Florkowski, B. Friman
The spatial dependence of static meson correlation functions at finite baryon density is studied in the Nambu -- Jona - Lasinio model. In contrast to the finite temperature case, w…
Effects of the Spin-Orbit and Tensor Interactions on the and Excitations in Light Nuclei
M. S. Fayache, Y. Y. Sharon, L. Zamick +2
The effects of varying the spin-orbit and tensor components of a realistic interaction on excitation rates and are studied on nuclei in the and shells.…
Deriving the quark condensate within a finite Fermi system from the generating functional of chiral perturbation theory
Mariana Kirchbach, Andreas Wirzba
The generating functional of heavy baryon chiral perturbation theory at order O(Q^2) in the mean field approximation (with a pseudoscalar source coupling which is consistent with t…
From Chiral Lagrangians to Landau Fermi Liquid Theory of Nuclear Matter
Bengt Friman, Mannque Rho
A simple relation between the effective parameters of chiral Lagrangians in medium as predicted by BR scaling and Landau Fermi liquid parameters is derived. This provides a link be…
Photoproduction of vector mesons off nucleons near threshold
Bengt Friman, Madeleine Soyeur
We propose a simple meson-exchange model of the photoproduction of - and -mesons off protons near threshold ( less than 2 GeV). This model provides a good description of…
On the Coupling of the Meson to the Nucleon
M. Kirchbach, L. Tiator
The pseudoscalar and pseudovector coupling constants are calculated from an effective vertex associated with the triangle diagram. The predicted values are in agr…
