Nuclear matter hole spectral function in the Bethe-Brueckner-Goldstone approach

The hole spectral function is calculated in nuclear matter to assess the relevance of nucleon-nucleon short range correlations. The calculation is carried out within the Brueckner scheme of many-body theory by using several nucleon-nucleon realistic interactions. Results are compared with other approaches based on variational methods and transport theory. Discrepancies appear in the high energy...

Strange Hadronic Stellar Matter within the Brueckner-bethe-goldstone Theory

In the framework of the non-relativistic Brueckner-Bethe-Goldstone theory, we derive a microscopic equation of state for asymmetric and β-stable matter containing Σ− and Λ hyperons. We mainly study the effects of three-body forces (TBF’s) among nucleons on the hyperon formation and the equation of state (EoS). We find that, when TBF’s are included, the stellar core is almost equally populated b...

Superfluid nuclear matter calculations

We present a method to calculate nuclear matter properties in the superfluid phase. The method is based on the use of self-consistent off-shell nucleon propagators in the T-matrix equation. Such a complete treatment of the spectral function, is required below and around Tc due to a pseudogap formation in the spectral function. In the superfluid phase we introduce the anomalous self-energy in th...

The Relativistic Dirac-Brueckner Approach to Nuclear Matter

An overview on the relativistic Dirac-Brueckner approach to the nuclear many-body problem is given. Different approximation schemes are discussed, with particular emphasis on the nuclear self-energy and the saturation mechanism of nuclear matter. I will further discuss extensions of the standard approach, amongst other things the inclusion of non-nucleonic degrees of freedom, many-body forces a...

Strange nuclear matter within Brueckner-Hartree-Fock theory

We have developed a formalism for microscopic Brueckner-type calculations of dense nuclear matter that includes all types of baryon–baryon interactions and allows to treat any asymmetry on the fractions of the different species (n, p,Λ,Σ−,Σ0,Σ+,Ξ− and Ξ0). We present results for the different single–particle potentials focussing on situations that can be relevant in future microscopic studies o...
