In-Medium Baryon Interactions and Hypernuclear Structure
We introduce a microscopic and relativistic theory describing free scattering and finite nuclei for the octet baryons in a consistent quantum field theoretical framework based on Dirac-Brueckner theory and nuclear mean-field. In a first quantitative approach yet still heuristic for dealing with the Λ hyperon the quality of the description of finite (hyper)nuclei based on free meson exchange pot...
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 کاملBaryon Interactions in Nuclear and Hypernuclear Matter
The production and structure of Λ hypernuclei are investigated in field theoretical models. The production in coherent p+A reactions is investigated by means of a resonance model. Results of exploratory calculations for associated strangeness production are presented for proton reactions on 40Ca. The target single particle wave functions are obtained from DDRH theory with density dependent Dira...
متن کاملIn-medium Λ interactions and hypernuclear structure
We study the interactions of the octet baryons in a relativistic meson exchange approach connecting freespace and in-medium interactions with those in finite (hyper)nuclei. Our approach is based on the covariant meson exchange framework. To generate the effective microscopic interaction in finite nuclei an approach using Tmatrix theory with a three dimensionally reduced twonucleon propagator is...
متن کاملInteractions and Response Functions in Exotic Nuclei
The transition from mean-field to correlation dynamics is studied by nuclear many-body theory in nuclear matter and finite nuclei at extreme isospin. In-medium interactions in nuclear and hypernuclear matter are described by DDRH theory with density dependent meson-baryon vertex functionals. Dynamical correlations from pairing interactions and core polarization are found to increase strongly wh...
