Cold quark matter

TL;DR: In this article, a perturbative calculation of the equation of state of cold but dense QCD matter with two massless and one massive quark flavor was performed, and it was shown that perturbation theory converges reasonably well for quark chemical potentials above 1 GeV.

SU(3) chiral dynamics with coupled channels eta and kaon photoproduction

TL;DR: In this paper, the s-wave amplitudes of the SU(3) chiral meson-baryon Lagrangian with a coupled channel potential were identified in a Lippmann-Schwinger equation, and the strangeness S = −1 resonance Λ(1405) and the S 11(1535) nucleon resonance emerged as quasi-bound states of anti-kaon/nucleon and kaon/Σ-hyperon.

Nuclei in a chiral SU(3) model

TL;DR: In this article, the condensate value of the strange scalar meson is found to be important for the properties of nuclei even without adding hyperons, and the model is reduced to a Walecka model structure embedded in SU(3).
Journal ArticleDOI

The properties of K̄ in the nuclear medium

TL;DR: In this article, the self-energy of the K − meson in nuclear matter is calculated in a selfconsistent microscopic approach, using a K N interaction obtained from the lowest-order meson-baryon chiral Lagrangian.
Journal ArticleDOI

Effective KN interaction based on chiral SU(3) dynamics

TL;DR: In this article, an energy-dependent, equivalent local potential in coordinate space is constructed such as to reproduce the full scattering amplitude of the chiral SU(3) coupled-channel framework.

Pion scattering lengths

TL;DR: In this article, a simple formula for pion scattering on any particle but a soft pion was given, and then extended to the more difficult case of pion-pion scattering.

Chiral dynamics in nucleons and nuclei

TL;DR: In this paper, the implications of spontaneous chiral symmetry breaking in QCD for processes involving one, two, or more nucleons are discussed, and the results of the analysis are discussed.
Journal ArticleDOI

Strange goings on in dense nucleonic matter

TL;DR: In this article, it was shown that at somewhat higher densities one finds a charged kaon condensate, driven to a large extent by the stgma term interaction with baryons.

Pions and Nuclei

TL;DR: In this article, the authors examine the underlying physical picture behind these phenomena in a systematic and coherent way, emphasizing the interplay between physical concepts and experimental facts more than the formal tools, which are presented in a series of appendices.

Pions and Nuclei

TL;DR: The pion has emerged as the main feature of nuclear structure beyond the traditional description in terms of neutrons and protons and it manifests itself in a number of areas which are normally only loosely interlinked, but intimately related to the pion-nucleon and pion nuclear interactions.
