0 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...

Density 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 ...

Density dependent hadron field theory for hypernuclei

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...

- 29 - Density Dependent Hadron Field Theory

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).

5 Density dependent relativistic hadron theory for hadron matter with inclusion of pentaquark Θ + ∗

The density dependent relativistic hadron field theory(DDRH) is extended to inclusions of pentaquark Θ+.We investigate In-medium properties of Θ+ and nucleons.As well as the neutron and proton,the effective Θ+ mass decreases as the baryon density increases,and remains larger than nucleons’.The effective mass of Θ+ is calculated,M∗ Θ+ ≃ 0.71MΘ+ at normal nuclear density with the fraction of Θ+ 0...
