Kaon Condensation in “Nuclear Star” Matter
The critical density for kaon condensation in “nuclear star” matter is computed up to two-loop order in medium (corresponding to next-to-next-to-leading order in chiral perturbation theory in free space) with a heavy-baryon effective chiral Lagrangian whose parameters are determined from KN scattering and kaonic atom data. To the order considered, the kaon self-energy has highly non-linear dens...
متن کاملKaon Condensation and Goldstone’s Theorem
We consider QCD at a nonzero chemical potential for strangeness. At a critical value of the chemical potential equal to the kaon mass, kaon condensation occurs through a continuous phase transition. We show that in the limit of exact isospin symmetry a Goldstone boson with the dispersion relation E ∼ p appears in the kaon condensed phase. At the same time, the number of the Goldstone bosons is ...
متن کاملKaon Condensation in Neutron Stars
We discuss the kaon-nucleon interaction and its consequences for the change of the properties of the kaon in the medium. The onset of kaon condensation in neutron stars under various scenarios as well its effects for neutron star properties are reviewed.
متن کاملNuclear kaon dynamics
An effective low energy Lagrangian density is applied to nuclear K−-dynamics. The free parameters, local s-wave couplings and SU(3)-symmetry constrained range terms are adjusted to describe elastic and inelastic K−-nucleon scattering data. The propagation and decay of the Λ(1405)-resonance and the Λ(1405)-nucleon hole state is studied self consistently with respect to the K−-propagation in isos...
متن کاملKaon Condensation in Dense Stellar Matter
This article combines two talks given by the authors and is based on works done in collaboration with G.E. Brown and D.-P. Min on kaon condensation in dense baryonic medium treated in chiral perturbation theory using heavybaryon formalism. It contains, in addition to what was recently published, astrophysical backgrounds for kaon condensation discussed by Brown and Bethe, a discussion on a reno...
