The recent past witnesses the growing interdependence between the physics of hadrons, the physics of relativistic heavy-ion collisions, and the physics of compact objects in astrophysics. A notable example is the kaon which plays special roles in all the three fields. In this paper, we first review the various theoretical investigations of kaon properties in nuclear medium, focusing on possible uncertainties in each model. We then present a detailed transport model study of kaon production in heavy-ion collisions at SIS energies. We shall discuss especially the elementary kaon and antikaon production cross sections in hadron-hadron interactions, that represent one of the most serious uncertainties in the transport model study of particle production in heavy-ion collisions. The main purpose of such a study is to constrain kaon in-medium properties from the heavy-ion data. This can provide useful guidances for the development of theoretical models of the kaon in medium. In the last part of the paper, we apply the kaon in-medium properties extracted from heavy-ion data to the study of neutron star properties. Based on a conventional equation of state of nuclear matter that can be considered as one of the best constrained by available experimental data on finite nuclei, we find that the maximum mass of neutron stars is about 2M⊙, which is reduced to about 1.5M⊙ once kaon condensation as constrained by heavy-ion data is introduced.pacs: 25.75.

“…In the near future the new DAΦNE facility at Frascati could deliver new data on kaon-nucleon scattering [1] and therewith help to establish a more profound understanding of the role played by the SU(3) flavor symmetry in hadron interactions. At present the low-energy elastic K + -proton scattering data set leads to a rather well established K + p scattering length with a K + p ≃ 0.28 − 0.34 fm [2]. Uncertainties exist, however, in the K + -neutron channel where the elastic cross section is extracted from the scattering data on the K + d → K + p n and K + d → K 0 p p reactions.…”

Relativistic chiral SU(3) symmetry, large-Nc sum rules and meson–baryon scattering

The relativistic chiral SU (3) Lagrangian is used to describe kaon-nucleon scattering imposing constraints from the pion-nucleon sector and the axial-vector coupling constants of the baryon octet states. We solve the covariant coupled-channel BetheSalpeter equation with the interaction kernel truncated at chiral order Q 3 where we include only those terms which are leading in the large N c limit of QCD. The baryon decuplet states are an important explicit ingredient in our scheme, because together with the baryon octet states they form the large N c baryon ground states of QCD. Part of our technical developments is a minimal chiral subtraction scheme within dimensional regularization, which leads to a manifest realization of the covariant chiral counting rules. All SU(3) symmetry-breaking effects are well controlled by the combined chiral and large N c expansion, but still found to play a crucial role in understanding the empirical data. We achieve an excellent description of the data set typically up to laboratory momenta of p lab ≃ 500 MeV.

“…The K − p rescattering plays a significant role in the case of the relative momenta q K − p falling in the low-momentum region q K − p < 100 MeV/c where the [99][100][101]). Therefore, to reduce this rescattering we will restrict ourselves in the following to the case of relative momenta q K − p ≥ 100 MeV/c 13 .…”

Within spectator model we study the reaction γd → K − Θ + p → K − K + np in the threshold energy region. We present the predictions for the exclusive and inclusive K − -meson angular distributions in the laboratory system for this reaction calculated for two possible parity states of the Θ + resonance at 1.5 and 1.75 GeV beam energies with and without imposing the relevant kinematical cuts on those parts of the sampled phase space where contribution from the main background sources, associated with the φ(1020), Λ(1520) production as well as with the K − p-rescattering in the final state, is expected to be dominant. We show that under chosen kinematics these distributions are sensitive to the Θ + parity and, therefore, can be used as a filter for the determination of its parity.
