Ii. Quark Condensates in Nuclear Matter
We summarize the current theoretical and experimental status of the spectral changes of vector mesons (ρ, ω, φ) at finite baryon density. Various approaches including QCD sum rules, effective theory of hadrons and bag models show decreasing of the vector meson masses in nuclear matter. Possibility to detect the mass shift through lepton pairs in γ −A, p− A and A− A reactions are also discussed.
متن کاملCorrelations in Exotic Nuclear Matter
In recent years, the interest in correlations inside nuclei became an important issue in nuclear physics. On the theoretical, side several calculations using different models including short-range correlation have been done for nuclear matter. However, there is still not much known about the role of correlations in neutron star matter containing hyperons. In our work we examined dynamical corre...
متن کاملCorrelations in hot asymmetric nuclear matter
The single-particle spectral functions in asymmetric nuclear matter are computed using the ladder approximation within the theory of finite temperature Green’s functions. The internal energy and the momentum distributions of protons and neutrons are studied as a function of the density and the asymmetry of the system. The proton states are more strongly depleted when the asymmetry increases whe...
متن کاملShort-range correlations in asymmetric nuclear matter
The spectral function of protons in the asymmetric nuclear matter is calculated in the self-consistent T -matrix approach. The spectral function per proton increases with increasing asymmetry. This effect and the density dependence of the spectral function partially explain the observed increase of the spectral function with the mass number of the target nuclei in electron scattering experiment...
متن کاملRange Correlations and Spectral Functions in Asymmetric Nuclear Matter
Dynamical correlations in asymmetric infinite nuclear matter are investigates in a transport theoretical approach. Self-energies due to short range correlations and their influence on the nucleon spectral functions are described in an approach accounting for a realistic treatment of mean-field dynamics and a self-consistently derived quasi-particle interaction. Landau-Migdal theory is used to d...
