- 29 - Density Dependent Hadron Field Theory

چکیده
The appearance of the QCD phase transition (QPT) atlow temperatures and high densities will change the prop-erties of neutron stars (NS). Whether this change will bevisible with telescopes and gravitational wave antennas de-pends strongly on the equation of state (eos) of hadronicand quark matter and on the construction of the phasetransition (PT).

Single particle properties of Λ hypernuclei in the density dependent relativistic hadron field theory
The density dependent relativistic hadron field theory is used to describe single particle properties of Λ hypernuclei. The discussion focuses on the spin-orbit systematics in the relativistic mean-field formalism by discussing general effects of the Λ continuum threshold and the delocalization of the Λ wave function. Theoretical predictions for the hypernuclear Auger effect are presented.
متن کاملApplication of the density dependent hadron field theory to neutron star matter
The density dependent hadron field (DDRH) theory, previously applied to isospin nuclei and hypernuclei is used to describe β-stable matter and neutron stars under consideration of the complete baryon octet. The meson-hyperon vertices are derived from Dirac-Brueckner calculations of nuclear matter and extended to hyperons. We examine properties of density dependent interactions derived from the ...
متن کاملDensity dependent hadron field theory.
In symmetric nuclear matter and stable nuclei one uses very often strictly phenomenological approaches, both in non-relativistic and relativistic formulation. In this contribution, a fully microscopic approach to nucleon-nucleon (NN) interactions in symmetric and asymmetric nuclear matter and extensions to hypernuclear matter will be discussed. Dirac-Brueckner theory is used to derive inmedium ...
متن کامل0 Density dependent hadron field theory for asymmetric nuclear matter and exotic nuclei
The density dependent relativistic hadron field (DDRH) theory is applied to strongly asymmetric nuclear matter and finite nuclei far off stability. A new set of in-medium meson-nucleon vertices is derived from Dirac-Brueckner Hartree-Fock (DBHF) calculations in asymmetric matter, now accounting also for the density dependence of isovector coupling constants. The scalar-isovector δ meson is incl...

The Density Dependent Relativistic Hadron Field (DDRH) theory, previously introduced and applied to isospin nuclei, is extended to hypernuclei by including the octet hyperons. Infinite matter Dirac-Brueckner theory for octet baryons and the derivation of in-medium DDRH baryon-meson vertices is discussed. From the properties of Dirac-Brueckner interactions it is found that hyperon and nucleon se...
